STRATIGRAPHIC FRAMEWORK AND LANDSYSTEM CORRELATION
FOR DEPOSITS OF THE SAGINAW LOBE,
MICHIGAN, USA
Ivan R. Guzman, M.S.
Western Michigan University, 2014
Since the time of the Last Glacial Maximum (LGM) the south-central portion
of the Lower Michigan Peninsula has been subject to several glacial advances and
retreats by the Saginaw lobe. As part of the U.S Geological Survey Great Lakes
Geological Mapping Coalition projects, several rotosonic borings were drilled
between 2006 and 2013 in Barry, Kalamazoo and Calhoun Counties. Gamma ray logs
and textural analyses were completed for each core. Five of these borings were
selected according to their diamicton (till) content and correlated using water well
logs and surficial geology maps. Glacial deposits such as diamicton serve as
evidence of glacial advance/retreat, and are usually present as nearly continuous
layers of sediments. Analysis of these layers affords the ability to accurately correlate
these types of sediments across an area. Three cores, BA-10-02 and BA-09-02, KA-
12-02 were drilled along the Kalamazoo moraine, each one containing 1 to 3
diamicton units separated by lacustrine sediments. The last two cores, CA-11-01 and
KA-13-01 were drilled on a drumlinized till plain; both contain 2 to 4 diamicton units
separated by outwash sediments. These diamicton units indicate the presence of at
least one major and two minor advances/retreats of the Saginaw Lobe.

CHAPTER I
INTRODUCTION
Since the time of the Last Glacial Maximum (LGM), sediments from three
lobes of the Laurentide Ice Sheet have dominated the Lower Peninsula of Michigan.
After the LGM, the first lobe to retreat was the Saginaw lobe, but not before
experiencing a series of small advances and retreats (Kehew et al, 2012a). Today,
only small portions of the surface landscape of the Saginaw Lobe has been mapped,
and very little is known about the characteristic of the region’s subsurface deposits as
well as how these deposits correlate with the advance and retreat of the ice. Recently,
studies have examined the subsurface deposits of the Saginaw Lobe, but only a few
borings have reached bedrock and fewer still have mapped the subsurface
stratigraphy of these glacial deposits. This study is intended to work out the
subsurface stratigraphy of the Saginaw Lobe. For that purpose, five rotosonic
boreholes were drilled in the counties of Barry, Kalamazoo and Calhoun, Michigan.
These borings were selected according to their thickness and stratigraphy.
The principal objective of this research is to identify and map major
stratigraphic units across the south-central portion of the Lower Peninsula of
Michigan related to glacial advances/retreats and investigate if these units can be
correlated through the area. A second objective of the study is to characterize the
glacial drift stratigraphy by interpretation and documentation of lithological units in
the Saginaw Lobe. Cores drilled along the Saginaw Lobe have shown diamicton a
2
few meters above the bedrock. This study will demonstrate if the diamicton units
correlate with each other and if the units are related to glacial advances/retreats.
Water well logs and a bedrock topographic map are used, as well as textural,
consistency and geochronology analysis to more clearly understand the glacial
deposition of the Saginaw Lobe.
Previous Investigations
The first studies to map the surficial deposits of the Saginaw Lobe, were
performed by Leverett and Taylor (1915). Based mostly on topographic analysis,
these studies describe Michigan surficial deposits by identifying and mapping various
glacial landforms, including the end moraines of the Saginaw Lobe, which they
associated with ice marginal positions. Martin (1955) compiled the first revised map
of the surficial geology of Pleistocene glacial deposits in Michigan. The map shows
the general distribution of glacial landforms across the southern Peninsula of
Michigan. Later Farrand and Bell (1982) published a revised map of the Quaternary
geology of southern Michigan that includes textural descriptions derived from the
previous soil surveys. Monaghan and Larson (1986) identified and correlated two
upper till units in south central Michigan, the Bedford and Fulton tills, using grain
size distribution and clay mineralogy analyses. Using only six 9-meter boreholes and
other surface samples, the authors traced the Bedford till from the Lansing Moraine to
the Kalamazoo Moraine and the Fulton till from the Lansing Moraine to the Tekonsha
Moraine. From this investigation they reach the conclusion that the Kalamazoo
3
Moraine of the Saginaw Lobe could be correlated with the Kalamazoo Moraine of the
Lake Michigan Lobe, and to the Powell Moraine of the Huron-Erie Lobe.
In the last fifteen years, new research has incorporated stratigraphy,
morphology, and clay mineral content of diamicton units into glacial studies (Taylor
et al., 1998; Fisher and Taylor, 1999; Kozlowski, 1999; Kehew et al., 1999;
Kozlowski et al., 2001; Fisher et al., 2003; Kozlowski et al., 2004; Kozlowski et al.
2005; Kehew et al 2012a). Woolever (2008) focused on the surface geology created
by subglacial meltwater of the Saginaw lobe. He concluded that several linear valleys
containing eskers in Barry County were tunnel valleys produced by meltwater erosion
at the base of the glacier. This finding helped to further understand the dynamic in
drainage systems of the ice sheet and how tunnel valley and eskers were formed.
Barnes (2010) analyzed till samples looking for systematic variation in the organic
matter content that could potentially explain the high iron concentration in
southwestern Michigan groundwater. He found that high organic carbon content was
most likely producing the higher iron concentration in the groundwater.
Recently Kehew et al (2012a) proposed a four landsystems approach to
classify the surface terrain of the Saginaw Lobe in Michigan according to the
sediment/landform relation in the lobe. This made it possible to interpret the glacial
dynamic and interactions between the ice and the substrate in the Saginaw Lobe.
Kehew et al (2012b) also described the role of subglacial meltwater flow systems in
the formation of tunnel valleys and concluded that subglacial water flow in tunnel
valleys played a crucial role on the drainage and stability of the ice sheets. Ewald
4
(2012) using data from six cores, reconstructed the depositional environment for the
glacial and lacustrine sediments present in Barry and Calhoun counties. She
concluded that several intervals within these borings were associated with a
proglacial or subglacial lake not previously identified in the Lower Peninsula of
Michigan.
Site Description
The area of study in this analysis is located in the south-central portion of the
Lower Peninsula of Michigan between the counties of Barry, Kalamazoo and
Calhoun (Figure 1). Between 2009 and 2013, five rotosonic boring were drilled in
several sites along these areas. The boring sites were selected to develop a
generalized stratigraphic framework and to determine the stratigraphy of tunnel
valleys in the study area. .
The first group consists of two boreholes drilled in Barry County; BA-09-02
drilled in 2009 and BA-10-02 drilled in 2010. The second group was drilled in
Calhoun County and consists of one borehole; CA-11-01 drilled in 2011. The third
group consists of two rotosonic boreholes drilled in Kalamazoo County; KA-12-02
was drilled on 2012 and KA-13-01 drilled in 2013. Most of the boreholes are located
within tunnel valleys or glacial uplands to aid us in better understanding the overall
drift stratigraphy in the area (Table 1).

CHAPTER II
GEOLOGY
Bedrock Geology
The glacial deposits across the Michigan Southern Peninsula are mainly
composed of material eroded from bedrock or previous sediment along the path of ice
movement from ice-sheet centers near Hudson Bay (Monaghan and Larson, 1986;
Dodson, 1993; Gardner, 1997; Flint 1999). Understanding the bedrock geology is
crucial towards gaining a fuller understanding of the stratigraphic settings of these
glacial sediments. The Michigan Basin is formed of sedimentary rock units of which
1% comes from Pennsylvanian age, 5% from Mississippian, 16% Devonian, 30%
Silurian, 21% Ordovician and 27% Cambrian (Cohee 1965; Dorr and Eschman 1970).
These sedimentary rocks can be grouped in a series of formations (Figure 2). The
bedrock formations are part of the Michigan Basin, which is an elliptical intracratonic
basin, located against the southern margin of the Canadian Shield (Gillespie et al.
2008).
Bedrock formations subcrop beneath the glacial deposits in a series of
irregular concentric rings (Figure 2). The ages of these formations range from
Cambrian at the margins of the basin to Pennsylvanian in the center, capped by a
small area of Jurassic rocks. The basin strata are mainly dominated by dolomite and
limestone, with a significant presence of siliciclastics (shale, sandstone and siltstones)
8
and evaporites (gypsum, halite) (Dorr and Eschman, 1970; Howell and Van der
Pluijm, 1999).
During the Pleistocene, bedrock topography played a crucial role in the
advance of the Laurentide Ice Sheet sub lobes by controlling their boundaries (Kehew
et al, 2012a; Ewald 2012). In the course of this time period, bedrock formations
across the Michigan basin were buried beneath thick unconsolidated glacial sediment
carried by the continental ice mass. Studies made by Dorr and Eschman, (1970) and
Harrell et al, (1991) have estimated that the thickness of these glacial deposits varies
in different locations ranging from 0 to more than 305 m (1000 ft).
The area of study is located in the southwestern part of the Southern Peninsula
of Michigan and includes the counties of Barry, Calhoun and Kalamazoo (Figure 2).
The uppermost bedrock formations in this area are part of the Mississippian System,
which extends northward from northern Indiana and northwestern Ohio to cover most
of the northern counties of Michigan’s Southern Peninsula. The system is largely
dominated by shallow marine terrigenous detritus (mostly shale), followed by
sandstones, and then carbonates and evaporates (Harrell et al, 1991). Several bedrock
formation subcrops within the study area such as the Marshall Sandstone, Coldwater
Shale, Bayport Limestone and Michigan Formation (Figure 2).
Coldwater Shale. The Coldwater Shale is located in the southwest part of the
study area. The Coldwater Shale subcrops predominantly in Kalamazoo County.
However, Coldwater Shale also exists in Calhoun County, as well as a small portion
in Barry County (Figure 2). The Coldwater Shale is mostly gray to bluish shale and
9
Figure 2. Bedrock geology, south-central portion of the Lower Michigan Peninsula.
Counties are outlined in black and labeled.
10
can be found interbedded with limestone and dolostone (Harrell et al, 1991).
According to Dorr and Eschman (1970) the fine-grained mud of the Coldwater Shale
was deposited at the beginning of the Early Mississippian after the Lower Peninsula
became an offshore marine environment.
Marshall Sandstone. The Marshall Formation is located directly northeast of
the Coldwater Shale and it crosses through Calhoun and Barry Counties (Figure 2).
The Marshall Sandstone is mostly formed by gray, pink and red sandstones and
siltstones, with an abundant clay matrix (Dorr and Eschman 1970; Harrell et al, 1991).
The Marshall Sandstone was deposited after a major regression in the seas at the
closure of Early Mississippian (Dorr and Eschman 1970).
Michigan Formation. The Michigan Formation directly overlies the Marshall
Sandstone. In the area of study, this formation can be found in Barry County (Figure
2). According to Dorr and Eschman (1970), the Michigan Formation is a marine
deposit of shale, gypsum, dolomite, limestone and small intervals of sandstone, which
was formed in the Late Mississippian by a transgression of the seas in Michigan. The
gray shale of the Michigan Formation is usually intebedded with sandstone in the
southern and central part of the basin, and carbonates and evaporate interbeds in the
west and north section (Harrell et al, 1991).
Bayport Limestone. The Bayport Limestone is the youngest of the
Mississippian rocks and is located to the northeast between the Michigan Formation
and the Saginaw Formation (Pennsylvanian). In the area studied, it can be found in
Barry and Calhoun Counties (Figure 2). It is comprised mainly of “Gypsiferous,
11
cherty, sparsely fossiliferous dolostone interbedded with some sandstone” (Harrell et
al, 1991).
Wisconsin Glaciation in Michigan
The last glaciation had a tremendous impact on modern topography and
glacial landforms of southwestern Michigan. This process began in the Pleistocene
approximately 2 million year ago, when the climate in the northern part of the
continent changed. During this period, glaciers advanced and retreated about twenty
times until their last major advance and retreat, called the Wisconsinan Glaciation
(Farrand, 1988). During this period, the Laurentide Ice Sheet experienced its biggest
expansion in North America.
The Wisconsin glaciation is divided into three sub episodes: the early
(Ontario), Middle (Elgin) and the Late (Michigan), based on the extent of the ice
margins (Johnson et al., 1997). During the early sub episode of the Wisconsin
glaciation between 65,000 – 79,000 yr. BP, ice advanced from the northeast and
dammed a lake in the Ontario Basin (Karrow 1984; Larson et al., 2001). Later during
the middle sub episode, between 65,000 and 35,000 yr. BP, the ice sheet extended
from the Ontario Basin to somewhere near the Finger Lakes region of New York,
where it terminated in a proglacial lake (Karrow 1984; Larson et al., 2001). Finally
came the late Wisconsin sub episode, between 35,000 and 10,000 yr. BP (Larson et
al., 2001).
12
The late Wisconsin was characterized by a series of major and minor advances
and retreats of the ice sheet (Grimley 2000; Larson et al., 2001). This period was one
of the most significant episodes because it is when all or most of the drift deposits in
the Lower Peninsula of Michigan were deposited during and following the Late
Glacial Maximum. After the Late Glacial Maximum, approximately 20,000 14
C BP,
the margin of the Laurentide Ice Sheet advanced in a series of sub lobes which at
some point covered the entire Great Lakes watershed (Dyke et al., 2002, Larson et al.,
2001, Ewald 2012). Three major lobes developed over Michigan: the Lake Michigan,
Saginaw, and Huron- Erie Lobes (Figure 3).
After the Late Glacial Maximum, the southern margin of the Laurentide Ice
Sheet began a general retreat northward into the Great Lakes watershed (Larson et al.,
2001). The Saginaw Lobe was the first of the three major lobes to readvance into
Michigan and northern Indiana (Kehew et al., 2005). The lobes were asynchronous,
and when the Saginaw Lobe began to wane or retreat the Lake Michigan and Huron-
Erie lobes advanced (Kehew et al., 2005) (Figure 3). The Kalamazoo Moraine is a
result of this interaction between the Saginaw and Lake Michigan Lobes. This
moraine appears to represent a prominent ice-marginal position and is attributed to
the Saginaw and Lake Michigan Lobe (Kehew et al., 2005). This current study is
concerned with glacial landforms and sediment deposited by the Saginaw Lobe in
Lower Peninsula of Michigan.

BP (right).
14
Saginaw Lobe Landsystems
Few studies have examined the Saginaw Lobe glacial landforms and even
fewer have attempted to characterize its subsurface deposits. A general classification
was made by Colgan et al (2005), who mapped the landsystems of the entire southern
Laurentide Ice Sheet margins. Recently, based on this classification, Kehew et al
(2012a) divided the surficial deposits of the Saginaw Lobe into four distinct
landsystems according to their morphology and depositional relationships (Figure 4).
Cores analyzed in this research will serve to correlate the glacial deposits with glacial
advances/retreat through these landsystems.
Landsystem 1 is composed of the Sturgis Moraine, which is a
terminal/recessional moraine, and a drumlinized till plain to the northeast. The Sturgis
Moraine is composed of glaciofluvial sediment with thick alluvial fans that slope off
the moraine (Kehew et al. 2012a). Tunnel valleys are present in this landsystem,
cutting and extending beyond the moraine. The drumlinized till plain is mostly
formed from sandy diamicton and is bounded by the bedrock contact of the
Coldwater Shale and overlying Marshall Sandstone to the north (Dodson, 1985;
Kozlowski, 1999, Kehew et al 2012a, Ewald 2012). Cores CA-11-01 and KA-13-01
were both drilled south of the Kalamazoo Valley on drumlins.
Landsystem 2 is bounded by of the Thornapple Valley in the north, the
Kalamazoo Valley in the south and contains the Kalamazoo Moraine. The Thornapple
Valley, a west flowing river valley, served as a channel to carry meltwater from the
15
Huron-Erie lobe (Kehew et al. 2012a). The Kalamazoo Valley, a major trench like
valley, begins as a network of tunnel valleys incised into the limestone bedrock with a
floor covered by numerous glacial boulders which are a product of the down cutting
of the overlying glacial drift (Kehew et al. 2012a; Kozlowski et al. 2005).
Landsystem 2 is mainly dominated by the Kalamazoo Moraine, which was first
described by Leverett and Taylor (1915), and it includes in its topography a
subglacial element, like tunnel valleys and eskers, which are covered by supraglacial
sediment. The landforms and sediments are believed to be the product of ice
stagnation and collapse, and include hummocks, kames and ice – walled lake plains
(Kehew et al. 2012a). Cores BA-10-02 and KA-12-02 were drilled in landsystem 2.
Landsystem 3 is located north of Thornapple Valley. The area is mainly
composed of open tunnel valleys and eskers. The Thornapple Valley is interpreted to
have carried meltwater from the Huron-Erie to the east (Kehew et al. 2012a). Core
BA-09-02 was drilled in this landsystem north of the Thornapple River Valley.
Landsystem 4 is mainly composed of recessional moraines formed from
backwasting of the Saginaw Lobe. For this research the area studied only covers
landsystems 1, 2 and 3.

CHAPTER IV
GEOCHRONOLOGY
Glacial Geochronology in Michigan
Geochronology of glacial events in Michigan was the subject of much
speculation before the development of Carbon 14 (14
C) radioactive dating methods in
the mid 1940’s. The 14
C method enabled the dating of organic material up to a
maximum of about 50,000 to 70,000 years old. As result of this technology, portions
of the Wisconsinan glacial time scale can be accurately dated. Sadly, organic material
from older glacial time like, the Illinoian deposits can’t be dated because the age limit
goes beyond the reach for 14
C dating (Dorr and Eschman 1970).
Some studies have been conducted in an attempt to accurately date glacial
advances/retreats from different glacial landforms. Organic remains, buried by till or
outwash, have assisted in dating some of these glacial advances (Dreimanis, 1977).
Moraines or sediments associated with moraines have been extremely useful for
radiocarbon dating. The 14
C methods have provided both maximum and minimum
ages to sediments below, within, and above the moraines (Briner, 2011). One of the
oldest glacial deposits dated in Michigan thus far corresponds to an unweathered,
unnamed till unit beneath the John Ball State Park organic bed in Grand Rapids.
Samples from this organic bed yielded 14
C ages between the ranges of 39,900 to
51,000 yr. BP (Zumberge and Benninghoff, 1969; Eschman and Mickelson 1986).
18
The unnamed till was thought to be from the early to middle Wisconsin age and is
believed to antedate deposition of the organic sediment by a short interval of time
(Eschman and Mickelson, 1986). According to Dreimanis (1977) such dates are rare,
especially for the interval between 13,000 and 17,000 B.P. which is close to the Late
Glacial Maximum. Recent studies from Colgan (2013) and Lingle (2013) dated a new
organic deposit beneath Hemlock Crossing Park in Ottawa. The organic sands were
located between two till unit from core OT-12-01 and yielded 14
C ages between the
ranges of 41,920 to 42,950 yr. BP. This implies, according to Colgan (2013), that
there is a significant amount of glacial sediment older that ~42,000 yr. BP around the
area of Ottawa and surrounding counties.
Most of the radiocarbon dating made on glacial landforms has been conducted
on wood surfaces or other plant remains. Diamicton (till) unit have only been directly
dated recently (Kehew et al, 2009). This study will obtain some radiocarbon dates on
till units from three rotosonic boreholes; BA-09-01, BA-10-02 and OT-12-01, and use
these dates to correlate the till units. Core BA-09-01 was analyzed by Ewald (2012)
and OT-12-01 by Lingle (2013), for their master’s thesis.
Radiocarbon Dating on Glacial Till: Main Concerns
Glacial deposits like diamicton document glacial advances and/or retreats.
Therefore, performing studies obtaining radiocarbon dates of diamicton units
represents a potential source of information about glacial events. However, there are
several potential problems regarding dating organic matter in soils. One of the main
19
problems in dating soil bulk organic carbon is that the 14
C ages obtained are too
young due to contamination by recent contribution of carbon. The formation of soil
organic matter is an ongoing process, in which fresh carbon is continuously
incorporated at different rates and in any size fraction (Wang et al. 1996). Because of
this, 14
C dates have been interpreted as minimum ages (Perrin et al., 1964;
Scharpenseel, 1971a,b, 1972, 1976; Cherkinsky and Brovkin, 1991, Wang et al. 1996).
The landscape in the Lower Peninsula of Michigan consists mainly in glacial
drift, and organic carbon in these sediments is concentrated in the diamicton units
(Kehew et al, 2009). The Lower Peninsula of Michigan has been subject to several
glacial advances/retreat during the late Wisconsinan and multiple sources of organic
carbon are present in the glacial drift; mid-Wisconsin wood, late-Wisconsin soil and
vegetation as well as clasts of coal are also disseminated in these deposits (Kehew et
al, 2009). Mid-Wisconsin and coal organic carbon could result in bias toward older
14C ages.
Radiocarbon dates from the bulk organic carbon of diamicton could serve as
an important source of information to correlate and estimate ages in different areas,
and assist in determining past glacial events. Core KAL-03-04 analyzed by Barnes
(2007), were used to correlate dates from the boreholes analyzed in this study.

CHAPTER IV
METHODS
The data used in this research comes from five rotosonic cores. The cores
were drilled as parts of the Michigan Geological Survey projects funded by the U.S
Geological Survey Great Lakes Geological Mapping Coalition with the purpose of
providing more detailed analysis of glacial geology throughout the region. These
cores were then taken to the Soil Laboratory at Western Michigan University (WMU)
for grain size distribution analysis. Diamicton samples from some of the cores were
collected and taken to the WMU Engineering College Geotechnical Laboratory for
consistency analysis (Atterberg Limits). Samples for 14
C dating were also collected to
be pretreated in the Geosciences Dept. Isotope Laboratory and have then sent to the
DirectAMS Laboratory in Seattle to be dated. The following methods and procedures
were used to accomplish the proposed research:
Particle Size Analysis
Five borings were chosen for textural/particle size analysis to determine the
grain size distribution. These tests were done according to the method modified from
Bowles (1978) to separate the 2µm clay particles. Sieves were selected according to
the ASTM protocol E 11. Similar techniques of analysis were used by Gardner (1997),
21
Flint (1999), Wong (2002), Beukema (2003), Barnes (2007), Woolever (2008) and
Ewald (2012). Results are presented in Appendix A.
Soil samples were taken about every 2 to 3 foot interval or when a change in
the soil layer was noted. The sample weight varies depending on the water content at
the time of collection and grain size distribution, but approximately 400 to 500 g of
sample was collected. As stated above, two sieving methods were used depending on
the type of samples: for coarse samples, the dry sieve method and for fine samples,
the wet method. The following procedure was used to analyze the grain size
distribution in coarse samples:
1. Approximately 400 to 500 grams of the sample was collected, placed in an
aluminum pan and dried in the oven at 105oC for at least 24 hours.
2. A pestle and a porcelain mortar were used to disaggregate the dried
samples. A rubber tip pestle was used to gently disaggregate the sample
(porcelain pestle was used for sample with high clay content). After this
the sample was weighed.
3. Seven sieves were stacked in order from: #5, #10, #18, #35, #60, #120,
#230 and bottom pan (order from the coarsest to the finest).
Approximately 400 grams of the disaggregated sample was poured into the
stack of sieves and covered with a top pan.
4. The stack of sieves was placed in the Ro-tap mechanical sieving device to
be agitated for 10 minutes.
22
5. After 10 minutes, the amount of particles retained in each sieve was
weighed and recorded.
6. The fines (silt and clay) from the bottom pan were stored in the oven and
then separated using the gravitational separation method based on Stokes’
Law (Hillel, 1998).
The following sieving procedure was used to analyze the grain size
distribution in samples with high content of clay and silt:
1. Approximately 400 to 500 grams of sample was collected, placed in an
aluminum pan and dried in the oven at 105oC for at least 24 hours.
2. The sample was disaggregated with a porcelain pestle and about 450
grams were taken and poured in a metal cup with tap water.
3. The sample in the metal cup was then agitated in a sediment stirrer
machine for 1 minute, then with a stir rod for another minute and washed
through a #230 sieve with a bottom pan to separate sand and gravel from
clay and silt.
4. The sample remaining in the #230 sieve was the sand and gravel. The
content was then rinsed in a separate container and allowed to dry in the
oven to be sieved again using the dry method explained above.
5. The sample captured in the bottom pan was the clay and silt. The content
was then rinsed into a separate container and dried in the oven at 105oC
for at least 24 hours. After drying, the sample was then mixed with the
23
fines that remained from the sieving of the sand and gravel portion. From
this mix 10 grams was collected for the silt and clay separation.
The following procedure was used for the silt and clay separation (modified
by Ewald, 2012):
1. Approximately 10 grams of the sample fines were collected and placed in
a 1000 ml beaker (if the sample was less than 10 grams, then the entire
sample was used).
2. An alkaline solution of 0.5% sodium hexametaphosphate (Na6O18P6) was
made to act as a deflocculant, and 700 ml of this solution was poured in
the beaker already containing the 10 gram sample.
3. The sample with the solution was then agitated in a sediment stirrer
machine for 10 seconds and then placed in an ultrasonic vibration device
for 20 minutes.
4. After 20 minutes, the sample was allowed to settle for 2 hours (120 min),
during this time the clay particles remained in suspension while the silt
settled to the bottom of the 1000 ml beaker.
5. After 2 hours the suspended clay and the settled silt were poured into
separate weighed aluminum pans and placed in the oven at105oC for 24
hours. The next day the weight of the aluminum pans was recorded.

Atterberg Limits
The Atterberg Limits were used to determine the clay consistency in 18
diamicton samples from three of the five borings. These borings were chosen based
upon location (landsystem), and relevance to the study. The test was performed
according to the American Society for Testing and Material (ASTM, 2010) protocols
to measure moisture content at which the sample changes from semi-solid to plastic
state (Plastic Limit) and from plastic to liquid state (Liquid Limit). Engineers have
been using this test since the 1900s for correlations of physical soil parameters and
soil identification (Das, 2010). Casagrande (1932) conducted several studies using the
liquid limit to correlate the plasticity index (PI) of different soil types. The following
procedure was used to prepare the samples for the liquid and plastic limit test:
1. Approximately 200 grams of the sample was taken and disaggregated
using a porcelain pestle and mortar.
2. The sample was poured in a #40 sieve with a bottom pan and sieved. This
process was repeated until about 120 to 200 grams of sample was retained
in the bottom pan.
3. The sample was weighed, recorded and then poured into a porcelain dish
for liquid and plastic limit test.
The liquid limit (LL) according to the ASTM (2010) is determined by
performing trials in which a portion of the soil sample is spread in a brass cup and a
groove is cut at the center with a grooving tool. Then with a mechanical device the
26
cup is lifted and then dropped until the groove is closed (Figure 5). The number of
drops and the moisture content is then recorded. The method used was the ASTM
One-Point Liquid Limit - Method B. The following procedure (ASTM, 2010) was
used to prepare the samples for the liquid limit (LL):
1. Deionized water was poured into the sample then thoroughly mixed until
the consistency to close the groove was between 20 and 30 blows. If the
number of blows exceeded 30 or was lower than 20, the sample was
removed from the brass cup and the water content was adjusted.
2. After getting a number of blows between 20 and 30, a portion of the
samples (from the closed groove) was removed to measure the water
content, then the soil from the brass cup was removed, then remixed in the
dish and a new sample is placed in the cup.
3. A second test was then made until the sample required the same number of
blows to close the groove as the first test or the difference in the number
of blows was equal to two. A portion of the sample was then removed to
measure the water content.
4. The Liquid Limit (LL) is the average of the two tests (to the nearest whole
number).
5. If the difference in values equal 1% the test had to be repeated.
The plastic limit (PL) according to the ASTM (2010) is determined by rolling
(in a ground - glass plate) a small portion of soil into a 3.2 mm diameter thread until
its water content is reduced to a point at which the thread crumbles and can no longer
27
be pressed together and rerolled. The following procedure was used to prepare the
samples for the plastic limit (PL):
1. From the soil prepared for the liquid limit test, a 20 gram sample was
selected, reducing the water content to a consistency in which it could be
rolled without sticking to the hand or the glass plate.
2. From the 20 grams, 2 grams were extracted and turned, by hand, into an
ellipsoidal mass. The ellipsoidal mass was then placed in the glass plate
and rolled until its diameter reached 3.2 mm.
3. When the samples had a 3.2 mm diameter, they were then broken into
three pieces and squeezed together, reformed and turned into an ellipsoidal
mass and rerolled again until the thread crumbled and could not be
reformed into an ellipsoidal mass and rolled again.
4. The Plastic Limit (LL) is the average of two tests (to the nearest whole
number). If the difference in values is equal or greater than 1.4% the test
had to be repeated.

Bulk Organic Carbon Assay
The bulk organic carbon assay was used to extract the carbon dioxide from the
diamicton units. The amount of organic carbon was then calculated and the carbon
dioxide was sent to DirectAMS Laboratory in Seattle for Carbon 14 dating. About 14
organic carbon samples were analyzed in the Stable Isotope Laboratory of the
Geosciences Department at Western Michigan University, from which 6 were
selected for Carbon 14 dating. The preparation procedure is listed below:
Inorganic carbon removal:
1. Approximately 7 grams of the sample was taken and disaggregated using a
porcelain pestle and mortar.
2. The sample was poured into a 15 mL plastic centrifuge tube, filled with
6N Hydrochloric acid (HCl), agitated and allowed to sit for 24 hours.
3. The next day, the sample was centrifuged for a total of 20 minutes; the
first 10 minutes at ½ speed and the next 10 minutes at ¾ speed.
4. After centrifugation, the acid was decanted into a waste container,
replaced with new acid and allowed to rest for 24 hours. This step was
repeated 4 to 5 times.
5. After the last centrifugation, the acid was decanted and replaced with
deionized water to remove the acid from the samples.
30
6. The samples were then agitated and centrifuged for a total of 20 minutes;
10 minutes at ½ speed and 10 minutes at ¾ speed. The deionized water
was then replaced.
7. Step 6 was repeated until the samples pH turned neutral (around 7), using
a pH indicator.
8. Once the samples pH turned neutral, the water was decanted in a waste
container and the sample were left drying in an oven at a temperature of
38 0C.
Sample Combustion and CO2 extraction:
1. Approximately 500 mg of the dry sample was taken and disaggregated.
2. The dry sample was poured into a 6 mm Quartz tube. The 6mm tube was
then placed inside a 9 mm Quartz tube with 1 gram of cupric oxide.
3. Air inside the 9 mm tubes was extracted on one of the vacuum lines. The 9
mm tube was then sealed with a blowtorch.
4. The 9 mm tube was then placed in the furnace and combusted for 3 hours
at a temperature of 900 0C.
5. The combusted sample was mounted onto an extraction unit in a vacuum
extraction line. The 9 mm was then broken releasing the CO2 gas into the
extraction unit and then to the vacuum line.
6. Liquid nitrogen was used to capture the CO2 gas in the U-shaped tube of
the vacuum line and release other gases like Nitrogen.
31
7. The liquid nitrogen was removed from the U-shaped tube and replaced
with a slush made with dry ice and alcohol (at 70 oC). This released the
CO2 gas trapping the moisture and water. The CO2 gas was then capture in
a 10 cm tube of the vacuum line with liquid nitrogen.
8. The liquid nitrogen was removed, releasing the CO2 gas inside the 10 cm
tube. The reading in the pressure gauge was then recorded to calculate the
amount of CO2 gas in the tube (micromoles).
9. A sample tube was added to collect the CO2 gas. Liquid nitrogen was used
in the sample tube to capture the CO2 gas.
10. The δ13
C of gas was then measured in a Mass Spectrometer. The gas was
returned to the vacuum line, sealed in a 9 mm Pyrex tube with a blowtorch
and set to DirectAMS for Carbon 14 dating.
Inorganic Carbon Assay
The inorganic carbon assay was used to extract the carbonates from the
diamicton units. Six samples were pretreated in the Stable Isotope Laboratory of the
Geosciences Department at Western Michigan University and then sent to the Stable
Isotope Laboratory from Oklahoma State University for isotope analysis. The
preparation procedure is listed below:
1. Approximately 20 mg of the sample was taken and disaggregated using a
porcelain pestle and mortar.
32
2. The sample was then poured into blood tubes. In addition, a 9 mm Pyrex
tube was glued inside the blood tube.
3. After the glue between the tubes was dry, Phosphoric acid (H3PO4) was
injected in the 9 mm tube glued to the blood tube. The blood tube was then
sealed with a plastic cap.
4. Air inside the blood tube was extracted on one of the vacuum lines and
then was taken to the water bath. The water bath was used to avoid 18
O
fractionation.
5. Then the next day, acid and sediment sample were mixed inside the blood
tube and the CO2 gas was extracted following the same procedure as the
bulk organic carbon assay.
Maps and Cross Section Data
Maps and cross sections were created using ArcGIS software program
ArcMap 10. Data used to create the maps, including water well logs, were imported
from the State of Michigan’s Geographic Data Library and wellogic data base, with
the exception of the rotosonic cores drilled in the field. This database is accessible on
the State of Michigan website. The data was translated into uniform lithological terms.
All of the lithological terms including the borehole data were combined into three
categories based on the grain size distribution (Table 2).
Lithologies were grouped as “Sand & Gravel” (yellow), “Silt & Clay” (blue)
and “Diamicton” (green). Clayey units mixed with gravel and/or sand were
33
interpreted as diamicton. This procedure is also used by the U.S Geological Survey
and recently by Ewald (2012). Bedrock topography data was obtained from Mr. John
Esch of the Michigan Department of Environmental Quality.

CHAPTER V
RESULTS
Several cores were drilled within the Saginaw lobe terrain in the Michigan
Southern Peninsula. These cores are described according to the landsystem in which
they were drilled. A textural classification system is used to express the general
characteristics in the borehole soils. Sediment textures for the cores BA-09-02, BA-
10-02, CA-11-01, KA-12-02 and KA-13-01 are classified using the U.S. Department
of Agriculture (USDA) textural classification method.
Landsystem 3: North of the Thornapple Valley
Cores BA-09-02 was drilled north of the Thornapple River Valley in a
northeast -southwest trending tunnel valley in Barry County. The area is located
within the range of landsystem 3 (Figure 4). Textural analysis was completed by
Ewald (2012) and is replotted in Figure 6.
BA-09-02
The stratigraphy in the core is composed mainly of diamicton and fine
sediments. The total depth of the core was -63.1 meters (207 feet) and it reached
bedrock at -57 meters (187 feet). Bedrock, in this area, comes from the Michigan
Formation (Figure 2), which is mainly shale. Three diamicton units are present below
a depth of 16.3 meters, separated by two thick layers of silt and clay. The
predominant particle fraction in this core is silt and clay (Figure 7).
35
The interval between 0 (surface) to -7 meters has two layers, one of sand and
one of gravelly sand (Figures 7, 8). The first layer (0.4 m) is a sandy loam consisting
mainly of sand, with an average normalized texture of 51.5% of sand, 34.1% silt and
14.4% clay. The gravelly sand unit is mostly coarse; clay is almost nonexistent in this
layer; it is composed of about 95% sand, 3.5% silt and 1% clay. The sand unit is
made up of mostly fine sand.
Between -7 to -16 meters is located a silty clay bed with an average
normalized texture of 1.2% sand, 66.6% silt and 32.2% clay, underlain by a sand
and silt unit between two gravelly sand layers (Figures 7, 8). The first gravelly sand
layer is formed by very coarse material with some sand, while the second is a mixture
of gravel, sand and silt.
The interval between -16 to -46 meters has two diamicton units separated by
two layers; a silt unit and a silty clay unit (Figures 7, 8). The upper till unit (Unit A-1)
is a uniform/compact clay loam diamicton with an average texture of 32.3% sand,
41.6% silt and 26.1% clay. The middle till (Unit A-2) has an average texture of
27.7% sand, 43.4% silt and 28.9% clay. The unit is very similar to the previous layer,
being comprised of a clay loam diamicton, uniform and compact, but with a higher
percentage of fines and a lower percentage of coarse particles. At -46 m, there is a
bed of sand separating part of the middle till unit, which could mean that the till unit
below the sand bed is not part of the middle till unit (Figures 6, 7).

Figure 8. Matrix texture (<2.00 mm) of all samples in BA-09-02. Green circles
represent diamicton, blue circles represent silt/clay and yellow circles represent
sand/gravel. The upper diamicton (Unit A-1) consists of sand and silt, with an
average texture of 32.3% sand, 41.6% silt and 26.1% clay. The middle diamicton
(Unit A-2) is dominated by silt and clay, with an average texture of 27.7% sand,
43.4% silt and 28.9% clay.
38
The till below the sand bed is a clay loam diamicton similar to the previous till units.
The last layer is between -47 and 54 meters and consists of a silty clay unit. This silty
clay layer is formed of an equal amount of fines with an average texture of 0.7% sand,
51.4% silt and 48% clay.
Landsystem 2: South of the Thornapple and North of the Kalamazoo Valleys
Two cores BA-10-02 and KA-12-02 were drilled south of the Thornapple
River Valley and north of the Kalamazoo River Valley. The boring BA-10-02 was
drilled in Barry County and KA-12-02 in Kalamazoo County. The area is located
within the range of landsystem 2 (Figure 4). The glacial features in this area include
the Kalamazoo Moraine between the Thornapple River Valley to the north and the
Kalamazoo Valley to the south.
BA-10-02
The stratigraphy in the core is composed mainly of diamicton, sand and silt
(Figure 9, 10). The boring was drilled to a depth of -85 meters (279 feet) and reached
bedrock at -73.15 meters (240 feet). The bedrock in this area is shale and comes from
the Michigan Formation (Figure 2). About three thick diamicton units are present in
the core. The first two units are coarse grained and the deepest one is finer.
Between 0 (surface) to -13 meters are interbedded sand and silt/clay in the
first four meters, followed by a unit of sandy diamicton interbedded with gravel
(Figures 9, 10). The diamicton (Unit B-1) is a sandy loam with an average texture of
39
66.7% sand, 25.1% silt and 11.1% clay. Sand and gravel lenses are present in the
middle and base of this till unit.
The interval between -13 to -36 meters is mostly dominated by sandy
sediments. The first six meters consist of a sandy loam, followed by a silt layer
(Figures 9, 10). The sandy loam has an average texture of 82.6% sand, 15% silt and
2.4% clay. The next five meters is comprised mainly of sand with a thin bed of silty
clay. Below this bed is the second diamicton unit (Unit B-2), a compact sandy loam
with gravel. This unit has an average texture of 77.6% sand, 18.1% silt and 4.3% clay.
Four meters of sand with some gravel are present below the diamicton.
In the interval between -36 to -66 silt fractions start to dominate (Figures 9,
10). A sandy loam unit is present in the first 8 meters, followed by a silt layer in the
next 10 meters. The sandy loam has an average texture of 55.7% sand, 38.7% silt and
5.6% clay. Interbedded diamicton (Unit B-3) with variable textures is present in the
interval -54 to -66 meters. A gravelly/sandy loam diamicton is located between -54
and -58 meters, with an average texture of 58.4% sand, 30.7% silt and 11% clay. A
gravel layer separates the second diamicton bed into upper and lower units. This part
is a clay loam diamicton formed mostly by 30.7% clay and 47% silt. The third
diamicton bed is separated by a silt layer. This bed consists mainly in sand and silt
with an average texture of 40.5% sand, 40.4% silt and 19% clay.
The last interval between -66 to -73 meters is mainly sand and diamicton
(Figures 9, 10). The first 5 meters are composed of interbeded sand and silt.

Figure 10. Matrix texture (<2.00 mm) of all samples in BA-10-02. Green circles
represent diamicton, blue circles represent silt/clay and yellow circles represent
sand/gravel. Upper diamicton units (Unit B-1, B-2) consist mainly in sand and silt
with an average texture ranging from 58.4% - 77.6% sand, 18.1% - 30.7% silt, 4.3% -
11.1% clay. The lower diamicton unit (Unit B-3) is mainly formed by silt and clay
with an average texture ranging from 22.3% - 40.5% sand, 40.4% - 47.0% silt, 19.0%
- 30.7% clay.
42
Underneath this layer is another diamicton bed. This bed is mainly a clay loam
diamicton, with 22.5% of gravel. The average normalized texture for this unit is 30%
sand, 42.1% silt and 27.9% clay. This unit is believed to be part of the shale bedrock.
KA-12-02
The boring was drilled to a depth of -81 meters (266 feet) and reached
bedrock at -79 meters (259 feet). The bedrock in this area is shale and comes from the
Michigan Formation (Figure 2). The stratigraphy in this core is diverse, but mostly
sand and gravel followed by intercalated silt and clay (Figures 11, 12). A diamicton
unit is located between thin sand lens in the intervals of -16 and -30 meters. The unit
is mainly fine graineds.
Interval 0 (surface) to -14 meters. The first 5 meters in this core are mainly sand,
followed by 6.5 meters of gravel. A thin bed of diamicton is present below the gravel.
This unit has an average texture of 50.3% sand, 22.5% silt and 27.2% clay. The final
interval is mostly made up fines; a silt layer is below the diamicton unit, followed by
a clay loam. The gravel percentage in these layers is below 1% (Figures 11, 12).
Interval -14 to -45 meters. A thick diamicton unit (Unit C-1) is lies between
two small layers of sand. The unit is 13 meters thick and has a loam texture with an
average normalized texture of 49.5% sand, 34.9% silt and 15.5% clay. The content of
gravel is less than 5 %, and is the only diamicton unit in this core.
43
Figure 11. Logplot Diagram of KA-12-02 showing lithology, gamma ray signature,
and grain size distribution. The core contains one thick diamicton unit. Lacustrine
sequences are present above the diamicton unit and between 49 and 65 meters. The
shale bedrock underlies thick coarse sediments.

represent diamicton, blue circles represent silt/clay and yellow circles represent
sand/gravel. The diamicton unit (Unit C-1) in this core has a mean texture of 49.5%
sand, 34% silt and 15.5% clay.
45
From a depth of -30 to -45 meters the core shifts from silty and clayey to sandy and
gravelly. Intercalated sand and gravel with some silts dominates this interval (Figures
11, 12).
The stratigraphy changes two more times between the depths -45 and -79
meters, first from sand to silt/clay and then, to gravelly sand followed by 3 meters of
gravel. The interval begins with a silt unit followed by a fine sand layer, at -48 meter
this setting changes to interbedded of silt/clay, and then to interbedded sand/silt.
Finally the core becomes coarser at -65 meters, with 10 meters of gravelly sand,
followed by 3 meters of gravel (Figures 11, 12).
Landsystem 1: South of the Kalamazoo Valley
Two cores, CA-11-01 and KA-13-01, were drilled south of the Kalamazoo
River valley. Core CA-11-01 was drilled on a drumlin, within the city of Battle Creek
in Calhoun County. Core KA-13-01 was also drilled on a drumlin, but south of the
Kalamazoo Valley and southeast of the city of Portage, Kalamazoo. Both cores fall
within the area of landsystem 1 (Figure 4).
CA-11-01
The stratigraphy in this core is composed mainly of diamicton. The boring
was drilled to a depth of -54.6 meters (179 feet) and reached bedrock at -54 meters
(177 feet). Bedrock in the area is siltstone of the Marshall Formation (Figure 2). Four
46
diamicton units are present in this core, separated by thick units of coarse sediments.
The predominant particle size fraction is mainly coarse (Figures 13, 14).
The first interval goes from 0 (surface) to -19.5 meters, and is mainly a sandy
loam diamicton. The diamicton unit (Unit D-1) has an average normalized texture of
68.9% sand, 22.1% silt, and 9.0% clay. The unit becomes more gravelly at greater
depths, with an average of 7.5% gravel in the upper section and 16.2% between the
middle and bottom sections. An interbedded unit of sand and gravel is present
between -3 and -6 meters. Below the diamicton, 1.5 meters of fine sand is present and
its marks a shift from sand to silt (Figures 13, 14).
Between -19.5 and -31 meters is the second diamicton unit (Unit D-2). One
meter above the diamicton, two beds, one of sandy loam and one of silt are present.
The sandy loam has an average normalized texture of 59.2% sand, 35.2% silt and
5.6% clay. A small bed of silt lies directly below the diamicton, followed by 4 meters
of gravel and another small bed of silt. The dimicton in this interval is a sandy loam
unit, with about 11.1% gravel and an average normalized texture of 60.1% sand,
28.5% silt and 11.4% clay (Figures 13, 14).
The interval from -31 to -41 meters is dominated mainly by gravel and sand.
Interbedded diamicton (Unit D-3) and gravelly sand is present in the first 5 meters,
followed by 4 meters of gravel. The last meter is occupied by a silt/sand layer.
Diamicton in this interval is a sandy loam unit with an average normalized texture of
66.5% sand, 21.6% silt and 11.9% clay. The amount of gravel in this diamicton unit is
an average of 11.1% (Figure 13, 14).

and grain size distribution. The core contains four thick diamicton units separated by
sand and gravel. Sand and gravel between diamictons are poorly sorted, and are
interpreted as outwash deposits. The bedrock is siltstone from the Marshall Formation.

represent diamicton, blue circles represent silt/clay and yellow circles represent
sand/gravel. Diamicton units in this core have a high amount of gravel and sand. The
mean texture of the upper two diamictons (Unit D-1, D-2) are 68.9% sand, 22.1% silt,
9.0% clay, and of 59.2% sand, 35.2% silt, 5.6% clay. The lower two diamictons
(Unit D-3, D-4) have a mean texture of 66.5% sand, 21.6% silt, 11.9% clay and
40.8% sand, 40.4% silt, 18.8% clay.
49
The last interval, between -41 to -54 meters, is mainly diamicton finer than the
upper till unit (Figure 13, 14). The diamicton unit (Unit D-4) is divided at -50 meters
by 1.5 meter of silt, and above the unit, 4 meters of gravelly sand. The first diamicton
in this interval is a loam unit with an average normalized texture of 40.8% sand,
40.4% silt and 18.8% clay. Gravel percentage is low in this unit, about 1.8%. The
second diamicton is another sandy loam unit, located beneath the silt layer. The
average normalized texture is about 71.3% sand, 23.6% silt and 5.2% clay.
KA-13-01
The stratigraphy in this core is composed of more than 70% sand/gravel, and
sandy diamicton. The boring was drilled to a depth of -48.5 meters (159 feet) and
reached bedrock at -47 meters (154 feet). Bedrock in the area is shale of the
Coldwater Shale (Figure 2). At least two diamicton units are present in this core,
separated by thick layers of coarse sediments. The predominant particle fraction is
gravel, followed by sand (Figures 15, 16).
A diamicton unit (Unit E-1) is located between 0 and -15 meters and it split by
a small sand bed at -6 meters. The first unit is mainly formed by loamy sand with
13% gravel and an average normalized texture of 64.0% sand, 28.4% silt and 7.6%
clay. Interbedded diamicton and gravel/sand is present beneath the small sand bed at -
6 meters. The unit is a sandy loam diamicton with an average texture of 63.5% sand,
30.6% silt and 5.8% clay. A thick gravel unit is present below the diamicton,
50
followed by another unit of sand. The gravel is about 3.5 meters thick (Figures 15,
16).
The interval between -15 and -37 meters is mainly composed of very coarse
sediment (Figures 15, 16). The first bed is composed of 6 meters of gravel, which is
very coarse with some sand; clay/silt is very low in this unit. The next 5 meters
include intercalated gravelly sands with a gravel bed between them. Interbedded sand/
gravel occupy the next 9 meters, followed by 3 meters of gravel.
The last diamicton unit (Unit E-2) is located between two sand units in the
interval that goes from -37 to -47 meters. The unit is a sandy loam diamicton, uniform
and compact, low on gravel (about 3.8%), with an average texture of 59.1% sand,
29.0% silt and 11.9% clay. The sand units above and below the diamicton are form
mostly by fine sand and some silt. Gravel is present only in a small bed above the
diamicton unit (Figures 15, 16).

mean texture of the upper diamicton (Unit E-1) is 64.0% sand, 28.4% silt, 7.6% clay,
and the lower diamicton (Unit E-2) of 59.1% sand, 29.0% silt and 11.9% clay.

Diamicton Clay Consistency
The clay consistency of diamicton samples from cores BA-09-02, BA-10-02
and CA-11-01was tested with the plastic and liquid limit test (Table 3). Samples from
these boreholes are mostly inorganic clay with low to medium plasticity. The result
indicates a strong correlation between plasticity indexes in diamicton between the
depths of -46 to -72 meters. The following are the results of the plastic and liquid
limit test:
BA-09-02: According to the plasticity index, the clays in these diamictons
range from low to medium plasticity. Samples from the upper and lower diamicton
consist of low plasticity clay. Diamictons samples between the intervals -22 to -46
meters are formed by medium plasticity clay, close to high plasticity. Clay color
varies between brown and gray. The diamictons in this core contains higher clay
content. Bedrock in the area is shale, which is a possible clay source in the diamicton
(Table 3).
BA-10-02: According to the plasticity index, clay in these diamictons varies
from slight to low plasticity, close to medium plasticity in samples between -10 and
-55 meters. The clay between intervals -12 to -32 meters is slightly plastic to almost
non plastic, provably due to the high silt content in these diamictons. Silt content
becomes lower in diamictons samples close to bedrock. Clay color varies from orange
to brown and dark gray. Bedrock in the area is also shale, and this explains the dark

gray color in the clays. Diamicton below -55 meters, near the shale bedrock has low
plasticity (Table 3).
CA-11-01: According to the plasticity index, the clays in these diamictons are
slightly plastic, approaching a value of zero plasticity between the intervals of -9 to
-25 meters. The plasticity increases from low to medium between -46 and -47 meters
depth. Clay color in these diamictons varies from light brown to gray, with gray
diamicton having the lowest plasticity. The bedrock in the area is mainly siltstone,
which doesn’t contain a clay source (Table 3).
Cross Section A-A’
Cross section A-A’ has been constructed between Barry, Kalamazoo and
Calhoun Counties and it shows the general distribution of glacial deposits from the
Saginaw Lobe (Figure 17). The cross section includes water well logs within 826
meters of the cross section line, as well as cores BA-09-02, BA-10-02, KA-12-02,
CA-11-01 and KA-13-01. Red dashed lines represent the boundaries between
sedimentary packages. Water well logs are grouped into three categories according to
grain size.
Boreholes BA-09-02 and BA-10-02. Water well logs between the cores BA-
09-02 and BA-10-02 indicate that uplands are mainly underlain by fine sediments
such as silt/clay and fine - grained sediment mixed with diamicton (Figures 17, 18).
Ewald (2012) interpreted the high silt and clay content as a possible lacustrine origin.
A few deposits of coarse sediment occur in the middle section of the profile, followed

by sandy diamicton mixed with clay above the bedrock. According to the water well
logs, sediments in the Thornapple valley consist mostly of sand in the first -24 meters
and become mixed with diamicton and clay/silt until it reaches the bedrock.
Boreholes BA-10-02 and KA-12-02. Water well logs between the cores BA-
10-02 and KA-12-02 indicates diversity in the uplands stratigraphy (Figures 17, 18).
The northern section, close to core BA-10-02, consists of thick intervals of silt/clay
and fine grained sediment mixed with diamicton. The middle section contains a layer
of thick coarse sediments, which is mainly sand and gravel. The silt/clay continues
below the sand, followed by a thick interval of sandy diamicton.
Uplands on the southern section, close to core KA-12-02, are comprised of
about 50 meters of coarse sediment, followed by a thick interval of diamicton mixed
with silt/clay and sand. A small layer of sand separates some of the silt/clay from the
diamicton.
Boreholes KA-12-02 and CA-11-01. Coarse and fine sediments intercalate
between cores KA-12-02 and CA-11-01. According to the water well logs, uplands
near core KA-12-02, consist primarily of coarse sediments and sandy diamicton, then
a few meters below silt and clay start to dominate the middle section, which is
dominated by an interval of sand (Figures 17, 18). The bottom section has a layer of
silt/clay, followed by sand. Water well logs, show that The Kalamazoo Valley is
underlain mainly by coarse sediment, with silt and clay are present below the sand. It
is possible that erosion removed part of the fine sediments. Stratigraphy near core

59
CA-11-01 consists mainly of diamicton. Around -37 meters below surface coarse
sediments start to appear, followed by diamicton and clay.
Boreholes CA-11-01 and KA-13-01. Uplands in the area consist mainly in
sandy diamicton and coarse sediments deposits (Figures 17, 18). Stratigraphy near
core CA-11-01 is mainly diamicton in the upper and bottom parts. The middle part is
mostly silt, clay and fine sands. The middle-bottom section between cores CA-11-01
and KA-13-01 is mainly sand. More data is needed to draw interpretations regarding
the extent of sand in the layer in this section. Near core KA-13-01 diamicton, silt and
clay appear again in the uplands, followed by a small layer of interbedded clay and
sand. Close to the bedrock, in the bottom part, is a sandy layer with some traces of
diamicton.
Radiocarbon and δ13
C Analyses
Samples from four boreholes were analyzed in the Geosciences Dept. Stable
Isotope Laboratory, and then sent to different laboratories for Carbon 14 dating.
Samples from cores BA-09-01, BA-10-02 and OT-12-01 were dated at DirectAMS
laboratory. The last core, KA-03-04 was analyzed by Barnes (2007) (Table 6).
Organic carbon content, along with δ13
C values, were also determined in the Stable
Isotope Laboratory in the Geosciences Department (Table 4). Inorganic carbon
(carbonates), along with δ13
C and δ18
O were analyzed by the Stable Isotope
Laboratory at Oklahoma State University (Table 5).
60
δ18
O (VSMOW) analyses on carbonates collected from the samples of
diamicton ranged between 23.8 and 25.0 per mil, and δ13
C (VPDB) analyses ranged
between -2.4 and 1.3 per mil (Table 5). These δ13
C values are commonly seen in
marine sediments, which indicate carbonate deposits of marine origin. This result is
consistent with the enriched δ18
O values, which are mainly seen in the dolomite/
limestone deposits. In addition glacial deposits around southwestern Michigan overlie
Mississippian bedrock, which consists of 47% carbonates (limestone, dolomite) (Dorr
and Eschman 1970).
δ13
C analyses on bulk organic carbon collected from the diamicton samples
ranged between -23.53 and -26.53 per mil (Table 4). These values suggest the
presence of C-3 plants, which is consistent with the climate and vegetation of
southwestern Michigan. In addition, radiocarbon ages extracted from the diamicton
units bulk organic carbon give similar dates between 9 and 11 meters in three of the
core samples (Table 6). Radiocarbon ages tend to get younger between 29 and 57
meter. The bulk organic carbon in these sediments appears to be late Wisconsin in
age.

CHAPTER VI
DISCUSSION
Geotechnical analyses, grain size, textural classification, consistency, along
with glacial lithologies described in previous chapters, were used to identify the
stratigraphic framework, to interpret lithologic units and to correlate sediments of
glacial advances/retreat. Correlation of units was focused on the diamicton units
based on their stratigraphy and grain size distribution. Glacial deposits such as
diamicton serve as evidence of glacial advance/retreat, and are usually present as
nearly continuous layers of sediments. Analysis of these layers affords the ability to
accurately correlate these types of sediments across an area. The five cores analyzed;
BA-09-02, BA-10-02, KA-12-02, CA-11-01 and KA-13-01, each have between one
and four diamicton units.
Core Interpretations
Core BA-09-02 was drilled in landsystem 3. The area represents stagnation
and tunnel valleys in the area are assumed to have been formed by subglacial
meltwater (Kehew et al. 2012a). The core BA-09-02 contains two thick diamicton
units separated by silt/clay units. Ewald (2012) interprets these silt/clay units as
lacustrine sequences based on their thickness, lamination and texture. Diamicton in
this core consists of thick clay loam units, one near the surface (Unit A-1), and the
other close to the middle section (Unit A-2) just above a silty clay unit (Figure 19).

represent upper diamicton (Unit A-1), orange circles represent middle diamicton
(Unit A-2). The lower diamicton samples have more silt and clay when compared to
the upper diamicton samples.

represent upper diamicton (Unit B-1), orange circles represent middle diamicton
(Unit B-2), black circles represent lower diamicton (Unit B-3). The middle diamicton
samples have more sand than the upper and lower units. In the lower diamicton
samples, sand content decreases and clay content increase with depth.
66
Figure 21. Matrix texture (<2.00 mm) of diamicton samples in KA-12-02. Red circles
represent upper diamicton (Unit C-1). Samples in this unit are mainly sandy and silty,
with an increase in clay content in the upper and bottom sections.
67
Clay consistency in these diamictons varies from low plasticity in the upper and
bottom to medium plasticity in the middle section.
Cores BA-10-02 and KA-12-02 were drilled in landsystem 2. Laminated silts
and clays sediments in the area are assumed to have been deposited in a
glaciolacustrine environment (Ewald, 2012). Clay consistency in the diamictons from
this boring varies from slight to low plasticity. Core BA-10-02 contains three main
diamicton units and is separated by lacustrine sequences. The upper (Unit B-1) and
middle (Unit B-2) diamictons are mainly sandy loam units. The lower diamicton
(Unit B-3) is a very coarse sandy loam unit with high gravel content (Figure 20).
Core KA-12-02 contains one thick diamicton unit of about 13 meters between
silt/clay sediments probably deposited by meltwater during deglaciation. The
diamicton (Unit C-1) is a loam unit composed mostly of sand and silt (Figure 21).
Core KA-12-02 is located in an ice marginal zone; sediments in this area are mostly a
product of the stagnation and melting of the Saginaw lobe. Lacustrine sequences are
present above the diamicton unit and between -49 and -65 meters. The shale bedrock
is overlain by thick coarse sediments. Both cores BA-10-02 and KA-12-02 seem to
correlate in at least one diamicton unit.
Cores CA-11-01 and KA-13-01 were drilled in landsystem 1. The surficial
geology of the area consists of drumlins and outwash deposits. Diamictons in this
area are mostly sandy units, with a clay consistency ranging from slight in the first
-30 meters, to low/medium below the -40 meters. Core CA-11-01 contains four thick

silt and clay than the upper units.

diamicton units separated by sand and gravel. Sand and gravel between diamictons
are poorly sorted, and are interpreted as outwash deposits. The first three diamicton
(Unit D-1, D-2, and D-3) are sandy loam units. The forth diamicton (Unit D-4) lies
above the bedrock and consists of a loam unit rich in silt (Figure 22). The bedrock is
siltstone, which explains the high silt content in the lowest diamicton unit. Core KA-
13-01 contains two diamicton unit separated mainly by gravel and sand. Both
diamictons are sandy units; the upper diamicton (Unit E-1) has a thickness of 11
meters, the lower diamicton (Unit E-2) has significantly more clay than the first one
and a thickness of 1.5 meters (Figure 23). Gravel followed by sand are the
predominant fractions in this core. Diamicton in drumlins were the product of
subglacial deposition and as the ice retreated outwash and other coarse sediments
were deposited along the area.
Landsystem Correlation across the Saginaw Lobe
Sediments in the uplands between landsystem 3, 2 and 1, consist mainly of
diamicton and lacustrine deposits. For this thesis sedimentary packages along the
south-central portion of the Lower Peninsula of Michigan have been tentatively
correlated in cross section A-A’ (Figure 25). Diamicton units indicate the presence of
at least one major and two minor advances/retreats of the Saginaw Lobe. Cores CA-
11-01 and KA-13-01 were collected from a drumlinized till plain across landsystem 1.
The bedrock elevation is shallow in this area, and decreases to the north and west of
the study area. Sediments in KA-13-01 vary from sandy diamicton, of which the
71

diamicton samples from depth between 0 to -31 meters; orange circles represent
lower diamicton samples from depth between -32 to -74 meters. The upper diamicton
samples have more sand when compared to the lower diamicton samples.

Figure 25. Cross Section A-A’: Proposed Correlation of Sediments. Correlated sedimentary packages in landsystem 1, 2 and 3. Glacial sediments were grouped in 3 different categories (Silt, Clay & Fine sand,
Sand&Gravel and Diamicton) for better interpretations. Solid gray lines the bedrock elevation. Sedimentary packages in the cross section indicate at least one major glacial retreat and two minor advances/retreats.
73
drumlins are formed, to gravel and some sand sequences. Glacial deposits become
finer close to core CA-11-01 (Figure 25). However, the area between CA-11-01 and
KA-13-01 is formed by outwash deposits; a fluctuation in the ice margin is the most
likely cause. Sediments tend to be coarsest close to KA-13-01 and finer near CA-11-
01. The ice lobe retreated from KA-13-01 leaving till and outwash deposit (coarse)
and paused 1 to 2 times before reaching the area near the Kalamazoo Valley. During
deglaciation, glacial deposits in this valley were eroded to or near the bedrock by a
downcutting event of high meltwater discharge that flowed through the area
(Kozlowski et al, 2005).
Sediments north of the Kalamazoo Valley consist of lacustrine (near core BA-
10-02) and outwash deposits (close to core KA-12-02), formed by stagnation and
downwasting of the ice lobe. North of the Kalamazoo Valley nearly continuous layers
of diamicton cross landsystem 2 and 3 (Figure 25). Glacial sediments in these two
areas are mostly lacustrine sequences, outwash and diamicton. Between 2 to 3
diamicton layers are present in this area, indicating at least one major glacial retreat
and two minor advances/retreats. Core BA-10-02 and KA-12-02 were drilled in
lansystem 2. Sedimentary packages observed around core KA-12-02 consist of a thick
layer of outwash deposit (sand) and diamicton. These sediments along with an
absence of lacustrine sequences point to a rapid melting in the ice lobe, leaving sand
and diamicton before reaching the area around core BA-10-02 where lacustrine
sequences began to reappear. Ewald (2012) explained that lacustrine sediments in the
area were the result of proglacial lake deposition, in which bedrock topography
74
played a major controlling factor. Lower bedrock elevations tend to impound most of
the lobe’s meltwater creating the right conditions for lacustrine sediments deposition.
Sedimentary packages across cores BA-09-02 and BA-10-02 evidence at least
three cyclical deposits of diamicton and lacustrine units, suggesting a series of
advances and retreats (Figure 25). Evidence provided by core BA-09-02 suggest that
at least two other cycles of advance and retreat took place within landsystem 3 after a
major retreat from landsystems 1 and 2. Final glacial events around the Thornapple
Valley include erosion by meltwater flow, probably from the Huron-Erie Lobe, which
eroded most of the upper sediments.
Interpretations and correlations made in this thesis related to the various
sedimentary packages across the Saginaw Lobe’s landsystems have been done using
the major stratigraphic units in the boreholes. Grain size distribution and sediment
stratigraphy were assumed to be the same as in their natural environment.
Additionally the 14
C method was used to date diamicton bulk organic carbon, to
identify with greater accuracy the cycles of advance and retreat across the ice lobe’s
landsystems. Unfortunately the method has proven ineffective in these glacial soils,
resulting in dates evidencing no correlation with each other or other previous
radiocarbon data (Table 5). This study suggests other geotechnical methods which
could help to identify and even determine diamicton genesis (subglacial or
supraglacial) like unit weight, vertical stress, compressibility and shear strength.
These types of analyses are beyond the scope of this project, but could be useful in
future studies.

CHAPTER VII
CONCLUSIONS
Five cores were analyzed to delineate the Saginaw Lobe subsurface drift
stratigraphy in the south-central portion of the Lower Michigan Peninsula. These
borings were selected according to their diamicton (till) content. Sedimentary
packages in cores BA-09-02, BA-10-02, KA-12-02 were mainly composed of
diamicton, clay and silt, while cores CA-11-01 and KA-13-01were mostly composed
of diamicton, sand and gravel. Diamicton units in these cores were correlated across
the area using water well logs, surficial geology maps and bedrock topography.
This study brings new information about the environment in which glacial
sediments were deposited and their relation with the Saginaw Lobe‘s advances and
retreats. The analyses indicate that sediments located between the Thornapple Valley
and Kalamazoo Moraine consists mainly of cyclical deposits of clayey diamicton and
lacustrine sequences, and south of the Kalamazoo Moraine by sandy diamicton and
very coarse outwash deposits. These glacial deposits serve as evidence of at least
three main glacial events: one major cycle of advances/retreats followed by two
minor cycles of advance/retreat. Bedrock topography also played an active role by
controlling the advance of the Saginaw lobe.
Bedrock topography delineated in this study also shows a correlation between
bedrock elevation and the distribution between coarse outwash deposits and lacustrine
76
sequences. Lower bedrock elevations tend to impound most of the lobe’s meltwater
creating the right conditions for lacustrine sediment deposition.
