Allstract
One hundred thirteen Apollo 17 rake samples ranging in weight
from 077 to 5778 g from stations lA 2 7 and 8 were studied macroscopshy
ically and under the stereomicroscope while fitiLl in the storage cabinets
of the Lunar Receiving Laboratory Houston rexas The rocks are described
and classfied into 8 groups namely mare lJasalt (60) mare basalt breccia
agglutinated (1) anorthosite cataclastic () anorthosi tic nori te or
troctolite (1) microbrecci1~ (43) green gassy rock (probably melted
breccia) (1) agglutinate (1) and soil clod (5) [he mare basalts were
subdivided on the middotbasis of grain size into very fine (2) fine (21) fine
to medium (1) mediwn (19) meclium to coanie (1) and coarse (16) mare
basslts Microbreccia subdivision was made on the basis of the degree of
coherence of their matrices into coherent-natrix brec cias (41) and friab1eshy
matrix microbreccias (2) 30iL clods also vary in their consistency and
were grouped into friable soil clods (2) and soil clods transitional to
friable-matrix microbreccias (3) Classif~cation If individual rocks is
often difficult because (1) their study wafi limited to stereomicroscopy
(2) some are partially covered by fine dust vhich makes recognition of
textures and minerals difficult and (3) they grade from one type into the
other Therefore this classification will feave to be modified after
detailed microscopic electron microprobe and chemical study

1 Introduction
In the present report descriptions and classifications of 113
Apollo 17 rake saJn[lles from stations lA 2 7 and 8 are given The purshy
pose of this study is to arrive at a preliminary classification of Apollo
17 rake samples based on macroscopic and stereOlLicroscopic examination
of the rocks while still in the storage cabinets of the Lunar Receiving
Laboratory Houston Texas mis preliminary classification has several
purposes First it aided us in selecting 54 representative samples from
the 113 total rake samples for our mineralogic IJetrologic bulk chemical
(via broad beam electron microprobe and neutron activation analysis)
mineral chemical (via focused beaJn electron microprobe analysis) and
trace element (via neutron activation analYilis) studies Second it may
serve as a petrologic basis for allocating ake samples to other Principal
Investigators for other studies such as age dating It is also hoped that
it may aid these investigators in interpreting their data before detailed
mineralogic and petrologic data are available
The classification proposed here Ls necessarily preliminary
The difficulties encountered in establishing the present preliminary
classification reEmlts from a number of lLmitations First examination
was restricted to stereomicroscopy of the samples while stiLL in the
storage cabinets in Houston Second some of the samples are partially
Neutron activation analysis will be carried out on the same sample for
which we will prepare electron microprobe sections in collaboration with
G Goles and R A Schmitt

covered by fine dust which makes identification of textures and minerals
difficult particularly in view of the fact that the samples could not be
altered in any way (eg broken) Third rocks sometimes grade from one
type into the other Hence the preliminary clas ification proposed here
Ifill have to be mocLt fied as more detailed mineralogic petrologic and
compositional daGa l)ecome available
2 Sample 10ca1ities
The samples described here are from fow localities at the
Apollo 17 landing site (Fig 1) namely stations IA (71000 numbering
sequence) 2 (72000 numbering sequence) 7 (T7000 numbering sequence)
and 8 (78000 numbering sequence) Of the 12 samples c011ecte6 at stashy
tion lA all are mare basalts AIl but one of the 12 station 2 samples
are coherent-matrix microbreccias the exception is a cataclastic anorshy
thosi te Station 7 yielded 9 microbreccias and 3 mare basalts and stashy
tion 8 yielded 16 mare basalts 14 microbreccias 5 soil clods
1 anorthosite norite or troctolite 1 green glassy rock and 1 agghtinate
(see section 4 Nwnerical sample inventory and sample index)
3 Classification
31 General characterization
Tbe 113 rake samples were classified on the basis of macroscopic
and stereomicroscopic examination while still in the storage cabiLets at
the Lunar Receiving Laboratory Houston Texas On the basis of texture
and mineral content the Apollo 17 rake srunples were classified iLto

Allstract
One hundred thirteen Apollo 17 rake samples ranging in weight
from 077 to 5778 g from stations lA 2 7 and 8 were studied macroscopshy
ically and under the stereomicroscope while fitiLl in the storage cabinets
of the Lunar Receiving Laboratory Houston rexas The rocks are described
and classfied into 8 groups namely mare lJasalt (60) mare basalt breccia
agglutinated (1) anorthosite cataclastic () anorthosi tic nori te or
troctolite (1) microbrecci1~ (43) green gassy rock (probably melted
breccia) (1) agglutinate (1) and soil clod (5) [he mare basalts were
subdivided on the middotbasis of grain size into very fine (2) fine (21) fine
to medium (1) mediwn (19) meclium to coanie (1) and coarse (16) mare
basslts Microbreccia subdivision was made on the basis of the degree of
coherence of their matrices into coherent-natrix brec cias (41) and friab1eshy
matrix microbreccias (2) 30iL clods also vary in their consistency and
were grouped into friable soil clods (2) and soil clods transitional to
friable-matrix microbreccias (3) Classif~cation If individual rocks is
often difficult because (1) their study wafi limited to stereomicroscopy
(2) some are partially covered by fine dust vhich makes recognition of
textures and minerals difficult and (3) they grade from one type into the
other Therefore this classification will feave to be modified after
detailed microscopic electron microprobe and chemical study

1 Introduction
In the present report descriptions and classifications of 113
Apollo 17 rake saJn[lles from stations lA 2 7 and 8 are given The purshy
pose of this study is to arrive at a preliminary classification of Apollo
17 rake samples based on macroscopic and stereOlLicroscopic examination
of the rocks while still in the storage cabinets of the Lunar Receiving
Laboratory Houston Texas mis preliminary classification has several
purposes First it aided us in selecting 54 representative samples from
the 113 total rake samples for our mineralogic IJetrologic bulk chemical
(via broad beam electron microprobe and neutron activation analysis)
mineral chemical (via focused beaJn electron microprobe analysis) and
trace element (via neutron activation analYilis) studies Second it may
serve as a petrologic basis for allocating ake samples to other Principal
Investigators for other studies such as age dating It is also hoped that
it may aid these investigators in interpreting their data before detailed
mineralogic and petrologic data are available
The classification proposed here Ls necessarily preliminary
The difficulties encountered in establishing the present preliminary
classification reEmlts from a number of lLmitations First examination
was restricted to stereomicroscopy of the samples while stiLL in the
storage cabinets in Houston Second some of the samples are partially
Neutron activation analysis will be carried out on the same sample for
which we will prepare electron microprobe sections in collaboration with
G Goles and R A Schmitt

covered by fine dust which makes identification of textures and minerals
difficult particularly in view of the fact that the samples could not be
altered in any way (eg broken) Third rocks sometimes grade from one
type into the other Hence the preliminary clas ification proposed here
Ifill have to be mocLt fied as more detailed mineralogic petrologic and
compositional daGa l)ecome available
2 Sample 10ca1ities
The samples described here are from fow localities at the
Apollo 17 landing site (Fig 1) namely stations IA (71000 numbering
sequence) 2 (72000 numbering sequence) 7 (T7000 numbering sequence)
and 8 (78000 numbering sequence) Of the 12 samples c011ecte6 at stashy
tion lA all are mare basalts AIl but one of the 12 station 2 samples
are coherent-matrix microbreccias the exception is a cataclastic anorshy
thosi te Station 7 yielded 9 microbreccias and 3 mare basalts and stashy
tion 8 yielded 16 mare basalts 14 microbreccias 5 soil clods
1 anorthosite norite or troctolite 1 green glassy rock and 1 agghtinate
(see section 4 Nwnerical sample inventory and sample index)

Tbe 113 rake samples were classified on the basis of macroscopic
and stereomicroscopic examination while still in the storage cabiLets at
the Lunar Receiving Laboratory Houston Texas On the basis of texture
and mineral content the Apollo 17 rake srunples were classified iLto

vugs and vesicles some of which are sometimes lined by what appears to
be ilmenite Some vesicles in 7]-5860 in additicm to ilmenite have
long needles of what may be pyroxene The dominalt grain sizes of these
rocks range from 001-03 mm and that of ilmenite near vugs in 715870
may be as large as 05 mm Isolated olivine grails in 785790 reach

Coarse mare basalts are dark brownish gray to brownish gray to
medium dark gray to medirun gray to dark gcay to olive gray in appearance
and have varying amounts of vugs and vesicles sOYletime~ with crystals
(pyroxene) projecting into them These rocks are coherent to friable
and have dominant grain size ranging from 00 3middot-0il mm In 715970 some
olivine crystals reach longest dimensions of over 1 mm Major minerals
are plagioclase (030) pyroxene (055-60) ilmenite (010) and someshy

Allstract
One hundred thirteen Apollo 17 rake samples ranging in weight
from 077 to 5778 g from stations lA 2 7 and 8 were studied macroscopshy
ically and under the stereomicroscope while fitiLl in the storage cabinets
of the Lunar Receiving Laboratory Houston rexas The rocks are described
and classfied into 8 groups namely mare lJasalt (60) mare basalt breccia
agglutinated (1) anorthosite cataclastic () anorthosi tic nori te or
troctolite (1) microbrecci1~ (43) green gassy rock (probably melted
breccia) (1) agglutinate (1) and soil clod (5) [he mare basalts were
subdivided on the middotbasis of grain size into very fine (2) fine (21) fine
to medium (1) mediwn (19) meclium to coanie (1) and coarse (16) mare
basslts Microbreccia subdivision was made on the basis of the degree of
coherence of their matrices into coherent-natrix brec cias (41) and friab1eshy
matrix microbreccias (2) 30iL clods also vary in their consistency and
were grouped into friable soil clods (2) and soil clods transitional to
friable-matrix microbreccias (3) Classif~cation If individual rocks is
often difficult because (1) their study wafi limited to stereomicroscopy
(2) some are partially covered by fine dust vhich makes recognition of
textures and minerals difficult and (3) they grade from one type into the
other Therefore this classification will feave to be modified after
detailed microscopic electron microprobe and chemical study

1 Introduction
In the present report descriptions and classifications of 113
Apollo 17 rake saJn[lles from stations lA 2 7 and 8 are given The purshy
pose of this study is to arrive at a preliminary classification of Apollo
17 rake samples based on macroscopic and stereOlLicroscopic examination
of the rocks while still in the storage cabinets of the Lunar Receiving
Laboratory Houston Texas mis preliminary classification has several
purposes First it aided us in selecting 54 representative samples from
the 113 total rake samples for our mineralogic IJetrologic bulk chemical
(via broad beam electron microprobe and neutron activation analysis)
mineral chemical (via focused beaJn electron microprobe analysis) and
trace element (via neutron activation analYilis) studies Second it may
serve as a petrologic basis for allocating ake samples to other Principal
Investigators for other studies such as age dating It is also hoped that
it may aid these investigators in interpreting their data before detailed
mineralogic and petrologic data are available
The classification proposed here Ls necessarily preliminary
The difficulties encountered in establishing the present preliminary
classification reEmlts from a number of lLmitations First examination
was restricted to stereomicroscopy of the samples while stiLL in the
storage cabinets in Houston Second some of the samples are partially
Neutron activation analysis will be carried out on the same sample for
which we will prepare electron microprobe sections in collaboration with
G Goles and R A Schmitt

covered by fine dust which makes identification of textures and minerals
difficult particularly in view of the fact that the samples could not be
altered in any way (eg broken) Third rocks sometimes grade from one
type into the other Hence the preliminary clas ification proposed here
Ifill have to be mocLt fied as more detailed mineralogic petrologic and
compositional daGa l)ecome available
2 Sample 10ca1ities
The samples described here are from fow localities at the
Apollo 17 landing site (Fig 1) namely stations IA (71000 numbering
sequence) 2 (72000 numbering sequence) 7 (T7000 numbering sequence)
and 8 (78000 numbering sequence) Of the 12 samples c011ecte6 at stashy
tion lA all are mare basalts AIl but one of the 12 station 2 samples
are coherent-matrix microbreccias the exception is a cataclastic anorshy
thosi te Station 7 yielded 9 microbreccias and 3 mare basalts and stashy
tion 8 yielded 16 mare basalts 14 microbreccias 5 soil clods
1 anorthosite norite or troctolite 1 green glassy rock and 1 agghtinate
(see section 4 Nwnerical sample inventory and sample index)

31 General characterization
Tbe 113 rake samples were classified on the basis of macroscopic
and stereomicroscopic examination while still in the storage cabiLets at
the Lunar Receiving Laboratory Houston Texas On the basis of texture
and mineral content the Apollo 17 rake srunples were classified iLto

Allstract
One hundred thirteen Apollo 17 rake samples ranging in weight
from 077 to 5778 g from stations lA 2 7 and 8 were studied macroscopshy
ically and under the stereomicroscope while fitiLl in the storage cabinets
of the Lunar Receiving Laboratory Houston rexas The rocks are described
and classfied into 8 groups namely mare lJasalt (60) mare basalt breccia
agglutinated (1) anorthosite cataclastic () anorthosi tic nori te or
troctolite (1) microbrecci1~ (43) green gassy rock (probably melted
breccia) (1) agglutinate (1) and soil clod (5) [he mare basalts were
subdivided on the middotbasis of grain size into very fine (2) fine (21) fine
to medium (1) mediwn (19) meclium to coanie (1) and coarse (16) mare
basslts Microbreccia subdivision was made on the basis of the degree of
coherence of their matrices into coherent-natrix brec cias (41) and friab1eshy
matrix microbreccias (2) 30iL clods also vary in their consistency and
were grouped into friable soil clods (2) and soil clods transitional to
friable-matrix microbreccias (3) Classif~cation If individual rocks is
often difficult because (1) their study wafi limited to stereomicroscopy
(2) some are partially covered by fine dust vhich makes recognition of
textures and minerals difficult and (3) they grade from one type into the
other Therefore this classification will feave to be modified after
detailed microscopic electron microprobe and chemical study

1 Introduction
In the present report descriptions and classifications of 113
Apollo 17 rake saJn[lles from stations lA 2 7 and 8 are given The purshy
pose of this study is to arrive at a preliminary classification of Apollo
17 rake samples based on macroscopic and stereOlLicroscopic examination
of the rocks while still in the storage cabinets of the Lunar Receiving
Laboratory Houston Texas mis preliminary classification has several
purposes First it aided us in selecting 54 representative samples from
the 113 total rake samples for our mineralogic IJetrologic bulk chemical
(via broad beam electron microprobe and neutron activation analysis)
mineral chemical (via focused beaJn electron microprobe analysis) and
trace element (via neutron activation analYilis) studies Second it may
serve as a petrologic basis for allocating ake samples to other Principal
Investigators for other studies such as age dating It is also hoped that
it may aid these investigators in interpreting their data before detailed
mineralogic and petrologic data are available
The classification proposed here Ls necessarily preliminary
The difficulties encountered in establishing the present preliminary
classification reEmlts from a number of lLmitations First examination
was restricted to stereomicroscopy of the samples while stiLL in the
storage cabinets in Houston Second some of the samples are partially
Neutron activation analysis will be carried out on the same sample for
which we will prepare electron microprobe sections in collaboration with
G Goles and R A Schmitt

covered by fine dust which makes identification of textures and minerals
difficult particularly in view of the fact that the samples could not be
altered in any way (eg broken) Third rocks sometimes grade from one
type into the other Hence the preliminary clas ification proposed here
Ifill have to be mocLt fied as more detailed mineralogic petrologic and
compositional daGa l)ecome available
2 Sample 10ca1ities
The samples described here are from fow localities at the
Apollo 17 landing site (Fig 1) namely stations IA (71000 numbering
sequence) 2 (72000 numbering sequence) 7 (T7000 numbering sequence)
and 8 (78000 numbering sequence) Of the 12 samples c011ecte6 at stashy
tion lA all are mare basalts AIl but one of the 12 station 2 samples
are coherent-matrix microbreccias the exception is a cataclastic anorshy
thosi te Station 7 yielded 9 microbreccias and 3 mare basalts and stashy
tion 8 yielded 16 mare basalts 14 microbreccias 5 soil clods
1 anorthosite norite or troctolite 1 green glassy rock and 1 agghtinate
(see section 4 Nwnerical sample inventory and sample index)

31 General characterization
Tbe 113 rake samples were classified on the basis of macroscopic
and stereomicroscopic examination while still in the storage cabiLets at
the Lunar Receiving Laboratory Houston Texas On the basis of texture
and mineral content the Apollo 17 rake srunples were classified iLto

Fine mare basalts are grayish black to dark gray in color and
show varying amolwt s of vugs and vesi cles Sometlmes vesi cles appear
to be lined by pJates of ilmenite (715460 715690) Dominant grain
size is less thaI 01 mm Major minerals are plagioclase (25-30)
pyroxene (060) aYJd ilmenite (010) and sometimes mafi c silicates
(possibly o2-ivinel (02-5)

Mediwn mare basalts are medhun dark gray to medium gray to
dark gray or dark brovnlish gray in color and exhibit varying allounts of
vugs and vesicles some of which are sometimes lined by what appears to
be ilmenite Some vesicles in 7]-5860 in additicm to ilmenite have
long needles of what may be pyroxene The dominalt grain sizes of these
rocks range from 001-03 mm and that of ilmenite near vugs in 715870
may be as large as 05 mm Isolated olivine grails in 785790 reach
sizes up to 007 rmn in longest dimensjon Major minerals are

Allstract
One hundred thirteen Apollo 17 rake samples ranging in weight
from 077 to 5778 g from stations lA 2 7 and 8 were studied macroscopshy
ically and under the stereomicroscope while fitiLl in the storage cabinets
of the Lunar Receiving Laboratory Houston rexas The rocks are described
and classfied into 8 groups namely mare lJasalt (60) mare basalt breccia
agglutinated (1) anorthosite cataclastic () anorthosi tic nori te or
troctolite (1) microbrecci1~ (43) green gassy rock (probably melted
breccia) (1) agglutinate (1) and soil clod (5) [he mare basalts were
subdivided on the middotbasis of grain size into very fine (2) fine (21) fine
to medium (1) mediwn (19) meclium to coanie (1) and coarse (16) mare
basslts Microbreccia subdivision was made on the basis of the degree of
coherence of their matrices into coherent-natrix brec cias (41) and friab1eshy
matrix microbreccias (2) 30iL clods also vary in their consistency and
were grouped into friable soil clods (2) and soil clods transitional to
friable-matrix microbreccias (3) Classif~cation If individual rocks is
often difficult because (1) their study wafi limited to stereomicroscopy
(2) some are partially covered by fine dust vhich makes recognition of
textures and minerals difficult and (3) they grade from one type into the
other Therefore this classification will feave to be modified after
detailed microscopic electron microprobe and chemical study

1 Introduction
In the present report descriptions and classifications of 113
Apollo 17 rake saJn[lles from stations lA 2 7 and 8 are given The purshy
pose of this study is to arrive at a preliminary classification of Apollo
17 rake samples based on macroscopic and stereOlLicroscopic examination
of the rocks while still in the storage cabinets of the Lunar Receiving
Laboratory Houston Texas mis preliminary classification has several
purposes First it aided us in selecting 54 representative samples from
the 113 total rake samples for our mineralogic IJetrologic bulk chemical
(via broad beam electron microprobe and neutron activation analysis)
mineral chemical (via focused beaJn electron microprobe analysis) and
trace element (via neutron activation analYilis) studies Second it may
serve as a petrologic basis for allocating ake samples to other Principal
Investigators for other studies such as age dating It is also hoped that
it may aid these investigators in interpreting their data before detailed
mineralogic and petrologic data are available
The classification proposed here Ls necessarily preliminary
The difficulties encountered in establishing the present preliminary
classification reEmlts from a number of lLmitations First examination
was restricted to stereomicroscopy of the samples while stiLL in the
storage cabinets in Houston Second some of the samples are partially
Neutron activation analysis will be carried out on the same sample for
which we will prepare electron microprobe sections in collaboration with
G Goles and R A Schmitt

covered by fine dust which makes identification of textures and minerals
difficult particularly in view of the fact that the samples could not be
altered in any way (eg broken) Third rocks sometimes grade from one
type into the other Hence the preliminary clas ification proposed here
Ifill have to be mocLt fied as more detailed mineralogic petrologic and
compositional daGa l)ecome available
2 Sample 10ca1ities
The samples described here are from fow localities at the
Apollo 17 landing site (Fig 1) namely stations IA (71000 numbering
sequence) 2 (72000 numbering sequence) 7 (T7000 numbering sequence)
and 8 (78000 numbering sequence) Of the 12 samples c011ecte6 at stashy
tion lA all are mare basalts AIl but one of the 12 station 2 samples
are coherent-matrix microbreccias the exception is a cataclastic anorshy
thosi te Station 7 yielded 9 microbreccias and 3 mare basalts and stashy
tion 8 yielded 16 mare basalts 14 microbreccias 5 soil clods
1 anorthosite norite or troctolite 1 green glassy rock and 1 agghtinate
(see section 4 Nwnerical sample inventory and sample index)

ACKNOWLEDGMENT
We wish to express our sincere appreciation to the members of
the Lunar Sample Curators Office Johnson 3pacecraft Center Houston
Texas and their contractors who have been most helpful during the
examination of the Apollo 17 rake samples We are particularly grateful
for the many excellent photographs of the BampleE and the assiBtance in
typing and editing thiB report Without their diligence this study would
not have been possible

1 Introduction
In the present report descriptions and classifications of 113
Apollo 17 rake saJn[lles from stations lA 2 7 and 8 are given The purshy
pose of this study is to arrive at a preliminary classification of Apollo
17 rake samples based on macroscopic and stereOlLicroscopic examination
of the rocks while still in the storage cabinets of the Lunar Receiving
Laboratory Houston Texas mis preliminary classification has several
purposes First it aided us in selecting 54 representative samples from
the 113 total rake samples for our mineralogic IJetrologic bulk chemical
(via broad beam electron microprobe and neutron activation analysis)
mineral chemical (via focused beaJn electron microprobe analysis) and
trace element (via neutron activation analYilis) studies Second it may
serve as a petrologic basis for allocating ake samples to other Principal
Investigators for other studies such as age dating It is also hoped that
it may aid these investigators in interpreting their data before detailed
mineralogic and petrologic data are available
The classification proposed here Ls necessarily preliminary
The difficulties encountered in establishing the present preliminary
classification reEmlts from a number of lLmitations First examination
was restricted to stereomicroscopy of the samples while stiLL in the
storage cabinets in Houston Second some of the samples are partially
Neutron activation analysis will be carried out on the same sample for
which we will prepare electron microprobe sections in collaboration with
G Goles and R A Schmitt

covered by fine dust which makes identification of textures and minerals
difficult particularly in view of the fact that the samples could not be
altered in any way (eg broken) Third rocks sometimes grade from one
type into the other Hence the preliminary clas ification proposed here
Ifill have to be mocLt fied as more detailed mineralogic petrologic and
compositional daGa l)ecome available
2 Sample 10ca1ities
The samples described here are from fow localities at the
Apollo 17 landing site (Fig 1) namely stations IA (71000 numbering
sequence) 2 (72000 numbering sequence) 7 (T7000 numbering sequence)
and 8 (78000 numbering sequence) Of the 12 samples c011ecte6 at stashy
tion lA all are mare basalts AIl but one of the 12 station 2 samples
are coherent-matrix microbreccias the exception is a cataclastic anorshy
thosi te Station 7 yielded 9 microbreccias and 3 mare basalts and stashy
tion 8 yielded 16 mare basalts 14 microbreccias 5 soil clods
1 anorthosite norite or troctolite 1 green glassy rock and 1 agghtinate
(see section 4 Nwnerical sample inventory and sample index)
3 Classification
31 General characterization
Tbe 113 rake samples were classified on the basis of macroscopic
and stereomicroscopic examination while still in the storage cabiLets at
the Lunar Receiving Laboratory Houston Texas On the basis of texture
and mineral content the Apollo 17 rake srunples were classified iLto

rocks progress Microbreccia subdlvision vTa made on the basis of the
degree of coherence of their matrices into coherent-matrix microbreccias

consistency and were grouped into friable Bo l clods (2) and soil clods

Fine mare basalts are grayish black to dark gray in color and
show varying amolwt s of vugs and vesi cles Sometlmes vesi cles appear
to be lined by pJates of ilmenite (715460 715690) Dominant grain

vugs and vesicles some of which are sometimes lined by what appears to
be ilmenite Some vesicles in 7]-5860 in additicm to ilmenite have
long needles of what may be pyroxene The dominalt grain sizes of these
rocks range from 001-03 mm and that of ilmenite near vugs in 715870
may be as large as 05 mm Isolated olivine grails in 785790 reach
sizes up to 007 rmn in longest dimensjon Major minerals are

Coarse mare basalts are dark brownish gray to brownish gray to
medium dark gray to medirun gray to dark gcay to olive gray in appearance
and have varying amounts of vugs and vesicles sOYletime~ with crystals
(pyroxene) projecting into them These rocks are coherent to friable
and have dominant grain size ranging from 00 3middot-0il mm In 715970 some
olivine crystals reach longest dimensions of over 1 mm Major minerals
are plagioclase (030) pyroxene (055-60) ilmenite (010) and someshy

ACKNOWLEDGMENT
We wish to express our sincere appreciation to the members of
the Lunar Sample Curators Office Johnson 3pacecraft Center Houston
Texas and their contractors who have been most helpful during the
examination of the Apollo 17 rake samples We are particularly grateful
for the many excellent photographs of the BampleE and the assiBtance in
typing and editing thiB report Without their diligence this study would
not have been possible

covered by fine dust which makes identification of textures and minerals
difficult particularly in view of the fact that the samples could not be
altered in any way (eg broken) Third rocks sometimes grade from one
type into the other Hence the preliminary clas ification proposed here
Ifill have to be mocLt fied as more detailed mineralogic petrologic and
compositional daGa l)ecome available
2 Sample 10ca1ities
The samples described here are from fow localities at the
Apollo 17 landing site (Fig 1) namely stations IA (71000 numbering
sequence) 2 (72000 numbering sequence) 7 (T7000 numbering sequence)
and 8 (78000 numbering sequence) Of the 12 samples c011ecte6 at stashy
tion lA all are mare basalts AIl but one of the 12 station 2 samples
are coherent-matrix microbreccias the exception is a cataclastic anorshy
thosi te Station 7 yielded 9 microbreccias and 3 mare basalts and stashy
tion 8 yielded 16 mare basalts 14 microbreccias 5 soil clods
1 anorthosite norite or troctolite 1 green glassy rock and 1 agghtinate
(see section 4 Nwnerical sample inventory and sample index)
3 Classification
31 General characterization
Tbe 113 rake samples were classified on the basis of macroscopic
and stereomicroscopic examination while still in the storage cabiLets at
the Lunar Receiving Laboratory Houston Texas On the basis of texture
and mineral content the Apollo 17 rake srunples were classified iLto

medium (19) mediwn to coan3e (1) and coarse (16) lJare basalts This
classification will lle modified based on morE quantitative
mineralogic-petrologc-chemical parameters a laboratory studies of these
rocks progress Microbreccia subdlvision vTa made on the basis of the
degree of coherence of their matrices into coherent-matrix microbreccias
(41) and friab1e-matrix microbreccias (2) [oL clods also vary in their
consistency and were grouped into friable Bo l clods (2) and soil clods

ACKNOWLEDGMENT
We wish to express our sincere appreciation to the members of
the Lunar Sample Curators Office Johnson 3pacecraft Center Houston
Texas and their contractors who have been most helpful during the
examination of the Apollo 17 rake samples We are particularly grateful
for the many excellent photographs of the BampleE and the assiBtance in
typing and editing thiB report Without their diligence this study would
not have been possible

Fine mare basalts are grayish black to dark gray in color and
show varying amolwt s of vugs and vesi cles Sometlmes vesi cles appear
to be lined by pJates of ilmenite (715460 715690) Dominant grain

Mediwn mare basalts are medhun dark gray to medium gray to
dark gray or dark brovnlish gray in color and exhibit varying allounts of
vugs and vesicles some of which are sometimes lined by what appears to
be ilmenite Some vesicles in 7]-5860 in additicm to ilmenite have
long needles of what may be pyroxene The dominalt grain sizes of these
rocks range from 001-03 mm and that of ilmenite near vugs in 715870
may be as large as 05 mm Isolated olivine grails in 785790 reach
sizes up to 007 rmn in longest dimensjon Major minerals are

Mediwn mare basalts are medhun dark gray to medium gray to
dark gray or dark brovnlish gray in color and exhibit varying allounts of
vugs and vesicles some of which are sometimes lined by what appears to
be ilmenite Some vesicles in 7]-5860 in additicm to ilmenite have
long needles of what may be pyroxene The dominalt grain sizes of these
rocks range from 001-03 mm and that of ilmenite near vugs in 715870
may be as large as 05 mm Isolated olivine grails in 785790 reach
sizes up to 007 rmn in longest dimensjon Major minerals are

Coarse mare basalts are dark brownish gray to brownish gray to
medium dark gray to medirun gray to dark gcay to olive gray in appearance
and have varying amounts of vugs and vesicles sOYletime~ with crystals
(pyroxene) projecting into them These rocks are coherent to friable
and have dominant grain size ranging from 00 3middot-0il mm In 715970 some
olivine crystals reach longest dimensions of over 1 mm Major minerals
are plagioclase (030) pyroxene (055-60) ilmenite (010) and someshy
