SUMMARY
During the 1966 field season 16 shallow stratigraphic holes were
drilled in the Barcaldine-Alpha-Tambo area of Queensland (between 23°001 to
2530' and 145o to 147° E). Units drilled range in age from Carboniferous to
Cainozoic.
The depth of the holes ranged from 104 to 413 feet and averaged
248 feet. The total footage drilled was 4472 feet, including 1129 feet of
coring. An average of 12% of coring was carried out in each hole. Core
recovery per hole ranged from 28-99% and averaged 84%.
Drilling took place between June 20 and October 12 over 73 days,
at an average rate of 4 days per hole.
As a result of the drilling, some of the mapping of the Jurassic
units in the Jericho Sheet area has been modified; the mapping of the Cretaceous
units was substantiated. The sandstones at the base of the Marine Cretaceous
sequence in the Tambo district were found to be discontinuous and no equivalent
of the Mimi Member of the Blythesdale Formation was found. Thinning of the
Hooray Sandstone over the Birkhead Anticline north of Tambo was proved.
Cores of coal for quality evaluation were cut in the Cretaceous
Winton Formation. Cores for palynological.examination were cut in the Joe Joe
Formation, Colinlea and Dunda Sandstones, the topmost Moolayember Formation and
Black Alley Shale. The Joe Joe Formation was found to underlie the extensive
area of Cainozoic sediments surrounding the Alpha township.

INTRODUCTION
The 1966 drilling programme was planned to provide lithological
and palynological control to supplement surface mapping undertaken during 1964
and 1965 by the Great Artesian Basin party. The area mapped during 1964 (Vine,
Jauncey, Casey and Galloway, 1965) and to a lesser extent in 1965 (Ekon, Gallowayan^ e4c6c
Sad Casey, 1966) was one in which there was little outcrop or only deeply weathered
exposure in the Jurassic sequence. Thus mnny formation determinations were
questionable.Additionally some holes were planned to obtain fresh samples of
coal for quality evaluation.Drilling was carried out by the Petroleum Technology Section; Mineral
Resources Branch of B.M.R.,during two periods, the first from June 20th to July
31st, the second from September 12 to October 12 - a total of 73 days. During
this time 16 holes were drilled to an average depth of 248 feet of which 12%
was coring (re-drilled holes excluded in both cases). Details of the drilling
are summarised in Table 1.Two holes were drilled at certain sites, the first hole being drilled
to obtain wire line logs from which the coring programme was drawn up, and the
second hole, cored at the selected intervals, thus minimising the amount of coring
necessary.Geological supervision of the drilling was provided by Galloway who
also carried out a preliminary exnmination.of the samples. Ingram carried out a
systematic re-examination of the cores and cuttings in Canberra and compiled
figures 2- 17. The final interpretation was by Galloway.
Nomenclature of arenVes follows Crook (1960). "Siltstone" is used
for grains 1/16 - 1/25 m.m. and the term "mudstone", for non-fissile sediments
of the clay size class, and "shale" for fissile mudstones. Grade sizes used are
those of Wentworth (1922).
Figure 1 shows the localities of the holes drilled, and drilling
statistics are set out in Table 1.

B.M.R. JERICHO 4 (map ref 45620557 Jericho)
Object:^To collect samples for palynological examination from a unit,
thought to be the Lower Permian Colinlea Sandstone.
Results:^0-90 Colinlea Sandstone, mainly quartzose sandstone
90-223'6" Joe Joe Formation, mudstoneoiltstone,fine grained'
labile sandstone, pebble conglomerate.
Comments:^Presence of quartzose sandstone (0-100') confirmed the surface
lithology, so the unit was probably Colinlea Sandstone. This interval, which was
weathered throughout, contained no mudstone or siltstone; the sandstone was
quartzose and sub-labile so no suitable material for palynology was encountered.
The presence, below 100 feet, of siltstone and mudstone, labile sand-
stone and pebble conglomerate indicates the presence of the Joe Joe Formation.
The hole was dry, and the lower half had collapsed before logging
could be attempted. The results of palynological examination of cores is
included in appendix 4: -
Cores:
Core 1,^213'^- 213'6", Length 6"^, recovered^6".
Core 2,^213'6" - 223'6", Length 10'0" , recovered 8'10".
B.M.R. JERICHO 5 (map ref 37140758 Jericho)
Object:^To drill in an area where the Ronlow Beds (regarded as including the
whole Jurassic sequence) were thought to be thin. It was intended to core the
whole sequence for a detailed palynological and lithological study in order to
see whether correlates of the differentiated Jurassic sequence (Hutton to Hooray
Sandstone) could be recognised.
Results:^0-289'6" Ronlow Beds, mainly sandstone, extensively weathered throughout,
unsuitable for palynology.
Comments:^Well-weathered sandstone did not justify abundant coring. Hole could
not be completed as rig incapable of recovering stuck drill pipe (fish recovered
later by Mayhew). As a result of extensive weathering, the hole did not achieve its
objective of providing material suitable for palynological study. Subsequently,
gamma ray logging of a water bore about twelve miles to the west resulted in a
re-interpretation of the surface geology. It now appears that Jericho 5 was drilled
in that part of the Ronlow Beds which correlates with the Hutton Sandstone.

.B,M.R. JERICHO 7, 8 and 9
These holes were drilled to examine the Jurassic sequence, in
particular the Injune Creek Group. BMR Jericho 7 apparently drilled a thick
sequence of Tertiary sediments before bottoming in Hutton Sandstone. Having
not achieved its objective, BMR Jericho 8 was sited east of Jericho 7 where no
Tertiary sediments were known, to occur and where it was thought that the Injune
Creek Group would be found at shallow depth. This hole appears to have been
drilled entirely in the Hutton Sandstone. Having still not drilled the Injune
Creek Group, BMR Jericho 9 was sited at, or just below, the base of the Marine
Cretaceous sequence, and penetrated the Hooray Sandstone Westbourne Formation
and was terminated in the Adori Sandstone.
B.M.R. JERICHO 7 (map ref 38310293 Jericho)
Object:^To examine the Jurassic sequence, in particular the Injune Creek
Group.
Results:^0 - 33 Quaternary alluvium,medium grained poorly sorted quartz sandstone.
33 -217 Tertiary Sediments
33 - 55 Silcrete, silicified quartz sandstone and quartz pebble conglomerate
55 -190 Medium grained quartz sandstone with common sandy pebble andgranule conglomerate.
190 -217 Very fine sandstone and siltstone with quartz pebble conglomerate
217 -413'3" Hutton Sandstone, fine to medium grained greyish orangequartzose and sub labile sandstone.
Comments:^Weathered throughout and may not be suitable for palynology. The
Tertiary Hutton Sandstone boundary is difficult to pick. Evidently no Injune Creek
Group Sediments were drilled. This is thought to be due to pre-Tertiary erosion
of the Injune Creek Group followed by inf ill with Tertiary sediments. As the Injune
Creek Group was not intersected, Jericho 8 was planned. .

B.M.R. JERICHO 8 (map ref 39170332 Jericho)
Object:^Follow up to BMR Jericho 7 to examine the Injune Creek Group on theeastern side of the possible Tertiary valley.
Results:^0 - 140 Hutton Sandstone, varicoloured fine to medium quartz sandstone,some coarse sandstone, some mudstone and silty mudstone.
Comments:^The well was evidently sited just below the base of the Injune CreekGroup. It is possible that Tertiary sandstones occur in the upper part of the hole
but it is not possible to pick a boundary from the cuttings. The absence of
conglomerates and very coarse sandstones which commonly occur in the Tertiary
sequence suggests that no Tertiary sediments occur in this hole. As the Injune
Creek Group had still not been penetrated, Jericho 9 was planned. The outcropspreviously regarded as Injune Creek Group in the Belleview - Narbethong area are
evidently Tertiary.
B.M.R. JERICHO 9 (map ref 37620277 Jericho)Object:^Follow up to Jericho 7 and.8 to examine the Injune Creek Group.This well was sited near the base of the Wallumbilla Formation so as to drill
through the Hooray Sandstone to the Injune Creek Group.
Results:^0 - 33 Cairozoic sediments33 - 198 Hooray Sandstone, light brown and red fine and medium sub
labile and labile sandstone.
198 - 331 Westbourne Formation of Injune Creek Group. Fine grainedlabile sandstone, siltstone and mudstone.
331 - 402 Adori Sandstone of Injune Creek Group. Coarse and very coarsequartz sandstone.
Comments:^The boundary between the Tertiary sequence and the Hooray Sandstoneis difficult to pick. It is possible that no Tertiary sediments were drilled and
that the uppermost part of the hole is deeply weathered Hooray sandstone.
The Westbourne Formation interval was picked by the lithological change
and confirmed by the Gamma Ray Log and palynological work. The thickness of the
Hooray Sandstone, compared with that indicated by gamma ray logs of nearby water
bores, is anomalously high. This suggests that a channel may have existed,at
the locality of Jericho 9, at the time of deposition of the Hooray Sandstone, but
there is doubt as to the position of the top of the Hooray Sandstone.
Arenaceous foraminif era (see Appendix 2) probably indicating a brackish
or shallow water marine environment occur at 230-240 feet. Their absence in the
remaining cuttings and cores indicate that these conditions were short lived and
local.
-8-
The results of palynological examination are included in Appendix 3.
Core analyses (see Appendix 5) show that the highest permeability
is from core 6 (2,500 - 5,500 millidarcys) while cores 1, 3 and 5 recorded from
250 to 750 millidarcys. Cores 3 and 4 generally recorded less than 100 millidarcys.

B.M.R. TAM 5 (5a) (map ref 42539194 Tambo)
Object:^(1) To examine the base of the Marine Cretaceous sequence and
to determine whether an arenaceous unit, similar to the Mimi Member of the
Blythesdale Formation could be recognised.
(2)To examine the upper and lower parts of the Hooray Sandstone
(3)To examine the Westbourne Formation.
Results:^0 - 731 6" Doncaster Member of the Wallumbilla Formation; thebasal part is not arenaceous and no equivalent of the Mimi Member of the
Blythesdale Formation was found.
731 6" - 225° Hooray Sandstone, 73161t-77'3" upper part, quartzose very
coarse sandstone, pebble conglomerate, sandy conglomerate. 77'3_.225' lower part,
sab-labile and labile sandstones, very fine and fine grained, some medium grained,
some mudStone and siltstone.
Comments:^The well penetrated all targets sought. Tambo 5a was drilled to corethe interval above Core I in Tambo 5. The thickness of the upper part of the Hooray
Sandstone, 3 feet 9 inches, is in contrast with the 100 feet in the type section,
12 miles east of Tambo 5.
The total thickness of the Hooray Sandstone in Tambo 5 was 151'6" while
in the-type section it was 250 feet. Tambo 5 was drilled on the crest of the Birkhead
Anticline whereas the type section of the Hooray Sandstone is in the syncline east
of the Birkhead Anticline. The thinning of the unit appears to have been entirely
in the upper part.

Whilst the basal part of the Döncaster Member was not arenaceous
in this hole, it was arenaceous in cores 1 and 2 of Tambo 3, sited about half
a mile west of Tambo 5. This confirms that the arenaceous basal part of the
Tambo Formation is discontinuous.
Core analyses (see Appendix 5) shows that core 4 had the best
permeability, which ranged from 2110 to 2590 millidercys; cores 5 and 6 had a
vertical permeability of approximately 50 millidarcys and a horizontal permeability
of 180-500 millidarcys. Porosity and permeability tests on cores 7 and 8 were
unsuitable for testing or were very low.
The results of palynological examination are included in Appendix 2.

B.M.R. TAMBO 6 (map ref 39449115 Tambo)
Object:^To core the interval of the Gamma Ray anomaly which was thought to
coincide with the Toolebuc Limestone.
Results:^0 - 162 Allaru Mudstone
162 - 210 Coreena Member of Wallumbilla Formation
-1 0-
Comments:^The gamma ray tool produced an abnormal log as compared with the .logs of nearby water bores; the tool later failed to function. The greatest
gamma ray anomaly was 130-135 feet, though high readings occur from 127-1_62 feet;
below 162 feet the readings are still much higher than those above 127 feet.
The zone of greatest gamma ray anomaly was cored but the lithology was not typical
of the Toolebuc Limestone.
However palynological work (see A?pendix 3) revealed that the interval
120-150 feet had a low spore content which Burger regards (pers.comm.) as typical
of the Toolebuc Limestone. Micropaleontological work (see Appendix 2) has revealed
a swarm of Hedbergella ( GlobigeFina) in the interval 120-150 feet and a
minor concentration in the interval 50-60 feet. Crespin (1963 p.19) states that
Globigerina is typical of the Toolebuc Limestone and does not list it as being
present in either the overlying or underlying units.
It is therefore evident that the absence of the Toolebuc Limestone is
not erosional but due to facies change.

B.M.R. TAMBO 7 (map ref 44609792 Tambo)
Object:^Evans (1966) refers to the conflicting information as to the age of the
Moolayember Formation in the Southern Jericho and Northern Tambo Sheet areas.
Samples collected from what was thought to be the top of this unit had produced
anomalous J 1 spores. This information was based on outcrop samples from an area
of poor outcrop, seismic shot hole samples from an area of sand cover, and cuttings
from South Pacific Limited. Birkhead No 1. To resolve this problem a hole was
drilled in an area of relatively good outcrop to obtain samples from what was almost
certainly the topmost Moolayember Formation for further palynological work.

B.M.R. AUGATHELLA 3 (map ref 48808775 AuRathella)
Objects:^To check:
(1)The interpretation that here the sand plain is underlain by the
Doncaster Member of the ftllumbilla Formation.
(2)IfIf the upper and lower parts of the Hooray Sandstone can be
recognised in this area.
(3) The thickness of the upper part of the Hooray Sandstone.
Results:^0 - 20 Quaternary sand
20 - 72 Doncaster Member of the Wallumbilla Formation
72 - 128 Upper part of the Hooray Sandstone
characterised by the presence of sandy pebble conglomerate and quartzose sandstone.
128 - 320 Lower part of the Hooray Sandstone, characterised by the
presence of labile sandstone and almost total lack of conglomerate.
320 - 387 Hooray Sandstone or uppermost Westbourne Formations consisting
of fine and very fine grained thinly interlaminated labile sandstone and coaly
labile sandstone with some cross bedding.
Comments:^The well confirmed that the sand plain is underlain by the Doncaster
Member of the Wallumbilla Formation. It confirmed that the upper part of the
Hooray Sandstone is thicker in this area (56 feet) than on the Birkhead Anticline
(3 feet 9 inches in Tambo 5, 5a).
The interval 320 - 387 feet may be regarded as either uppermost
Westbourne Formation or lowermost Hooray Sandstone depending upon the criteria
used in determining the boundary between the two formations. The type section of
the Westbourne Formation in Amoseas Westbourne No.1 (Exon 1966) consists almost
entirely of shale and siltstone, with sandstone confined to thin beds in the
basal part. However in outcrop, Exon, Galloway,Casey and Kirkegaard (1966) recognise
a sandy upper part of the Westbourne Formation but this description seems to
conflict with the description of the type section. This upper sandy part of the
Westbourne Formation appears to be similar to the sandy interval between 320
and 387 feet in B.M.R. Augathella 3.
The lower part of the Hooray Sandstone in the type section (Exon 1966)
is predominantly fine grained sandstone and thus also appears to be similar to
the sandy interval between 320 and 387 feet in B.M.R. Augathella 3.
In the type section the Westbourne Formation has electrical log
characteristics typical of a shale sequence, and is further characterised by high
gamma ray counts. Electrical logs of the problematical interval in Augathella No.
3 are similar to those of the Westbourne Formation type section, but unfortunately
no gamma-ray log of the interval could be obtained due to caved hole.
-14-
However a gamma ray log of water bore 6398 about 6 miles SE of Augathella 3
dhows the Westbourne type anomaly clearly and establishes that in the water bore the
Hooray Sandstone is over 400 feet thick. This is nearly twice the thickness in
Augathella No. 3 if the interval 320 to 387 feet represents the Westbourne Formation.
In the absence of any obvious structural or environmental reason for such a variation,
this difference in thickness is unlikely.
Palynological determinations (Appendix 3) from cores in the problematical
interval indicate a J5 age of deposition. Unfortunately determinations elsewhere
show that both the uppermost Westbourne Formation and the lower part of the Hooray
Sandstone were deposited during this period of time.
In the opinion of the senior author the balance of evidence favours the
interpretation that the problematical interval should be referred to the lower part
of the Hooray Sandstone, and that there is thus no evidence for major variations
in thickness of the lower part of the formation.
Porosity-permeability determinations (see Appendix 5) showed that cores
4,5,6,7, 10 and 12 had permeability factors generally from 500 to 2000 millidarcys.
Cores 2 and 11 had horizontal permeabilities of around 340 millidarcys, the remainder
were from 60-150 millidarcys, very low to non permeable or not determined due to
unsuitability of core for testing.

Objects:^To core coal for quality evaluation.
Results:^Cores 1 (50-60'3"), 3 (97-107), 4 (107-117) and 7 (165'2"-174'4")recovered bright, semi bright and dull coal. Details of analyses are included in
Appendix I. It is unlikely that the coal will be of economic value in the foreseeable
future.
Porosity-permeability analyses (see Appendix 5) showed that the cores
either have no permeability or were unsuitable for testing.
A plug from core 4 (11316"-114'1") has an average apparent grain .density,
including non interconnected voids, of 3.05 gq/cc. It is a fine silt size carbonate
rock, with only a few detrital grains. It is made up of laminae of brownish grey
material with thin lenticular interlaminae of white milky material.
A positive phosphate test was obtained using ammonium molybdate; however
the shapiro test indicates that the rock contains less than 5,% phosphate and probablyless than 1%. Thin section showed that the rock was very fine grained silt size and
composed of carbonate minerals, about 1% quartz and a trace of plagioclase feldspar.
When acid etched the rock was only weakly stained by Alazarin Red S indicating that
only a minor proportion of the carbonate was calcite. The milky white material was
identified by x-ray diffraction as mainly calcite with some siderite, and the brownish
grey material as mainly siderite with some calcite (C.D.Branch,BMR, pers.comm.).
The specific gravity of siderite is 3.8 which accounts for the high specific
gravity of the rock. The total thickness of the sideritic bed was 4i inches (113 feet
11 inches to 114 feet 4 inches). Re-examination of the non coaly parts of the
cores suggested that siderite, in addition to being common in certain horizons was
disseminated to a varying degree throughout the rest of the cored intervals, being
most common in the mudstone.laminae. This was proved by x-ray diffraction
(C.D.Branch, BMR, pers.comm.).
These results are of particular interest as they may well be the
clue to the apparently random positioning of the ironstone beds in the weathered
profile of the Rolling Downs Group. Siderite on weathering would lopfse carbonate
ions into solution and have iron oxide deposited in its place. It could be suggested
that the location of the iron stone is controlled by the presence of calcareous
layers. However the source of the Fe ions is still unexplained. If the iron were
to be supplied by the enclosing beds. then greater iron leaching close to the ironstone
body and progressively less leaching away from them would be expected, but this does
not occur.
With siderite as the host mineral, only the carbonate ions have to be
removed with simultaneous oxidation of the Fe ions.

CONCLUSIONS
The drilling is a useful and necessary adjunct to the field mapping.
It is necessary for confirming and supplementing of field information. This is
especially so in areas of poor outcrop, thinning and facies variation. It is
essential for the recovery of fresh samples for palynology, coal analysis,
porosity and permeability determination and petrology.
Most of the targets in the drilling programme were achieved.
The area dominated by sand plain between the outcrop of the Hutton
Sandstone and the Rolling Downs Group was found to be mostly underlain by Tertiary
sediments and not the Injune Creek Group (Jericho 7,8,9). It is probable that a
Tertiary valley was scoured through this country to form a tributary to the Alice
River.
The Cretaceous mapping was confirmed by Tambo 5,6, Augathella
1,2,3,4 and Adavale 1.
The basal glauconitic sandstones of the Doncaster Member of the
Wallumbilla Formation were proved to be discontinuous (Tambo 5,5a). The thinning
of the units over the Birkhead Anticline was also proved.
Further information regarding the lithology, thickness and
distribution of the Doncaster Member of the Willumbilla Formation as well as the
upper and lower parts of the Hooray Sandstone was obtained (Tambo 5, 5a, Augathella 3).
Cores of Cretaceous coal for analysis were successfully obtained
(Augathella 2,4, Adavale 1), the details of the analyses are included in Appendix 1.
The coal was found to be of no economic value in the foreseeable future.

Samples sought for palynological examination were also obtained
(Jericho 4, and 6, Tambo 7, 8 and 9); the results of this work are includedin appendices 3 and 4.
The Carey rig was totally unsuitable for Geological Branch work
because of its inability to attain target depths deeper than 50 feet in the
Bowen Basin and 150 feet in the Eromanga Basin.

APPENDIX I
RESULTS OF COAL ANALYSES CARRIED OUT BE GEOLOGICAL SURVEY OF QUEENSLAND
B.M.R. Augathella & Adavale Scout Bores
Coals from boreholes at Adavale and Augathella were received from
the Bureau of Mineral Resources for examination and analysis. The .coal sections
were logged and certain portions were then selected for analysis (Proximate
Analysis, Sulphur, Calorific Value, Specific Gravity and Coking Tests).'
Portions were also selected for petrographic examination and Ultimate and
Proximate Analysis. Results of analyses are shown on the attached tables.
A report on the petrographic examination is appended, together with typed
descriptions of the seams and graphic logs of the sections sampled.
The chemical, physical and petrographic data indicate that these
coals are of low rank and are non-coking.
-2-
Petrographic Studies of Adavale No.1 and Augathella Nos. 2 and 4 Vitrains
Lenses of vitrain representing compressed coalified fragments of
wood up to about 1 inches in length occurred in the coal seams found in the
Adavale No. 1 and Augathella No. 2 boreholes. This material was very similar.
in appearance to jet found in the Lias of Yorkshire, England.
In order to assess the rank of the ,coals in Adavale No. 1 some of
these lenses were removed from two of the seams for chemical analysis and
reflectance determinations, the results of which appear in the table.
The extremely high moisture contents of these samples made preparation
for reflectance determinations difficult. Alternative absorption of moisture
and drying out during and following the preparation technique tended to crack the
polished blocks and impart an uneven surface. Even though determinations were
Made directly following preparation, the uneveness which developed would certainly;
have introduced some error into the results and would have been responsible in
part for the fairly large variation in readings. However, most of this variation
is attributed to the marked heterogeneity of the samples which showed a cryptic
arrangement of cell walls and fillings under the microscope. The highest readings,
for example, were obtained on material which could have been phlobaphenite. Due to
the small size of most occurrenées of each entity and to the complexity of the
structure, selection of any one type of material for reflectance determinations
was impossible. The average of the readings, therefore, represents the whole of
the material in the vitrain and, as such, is more properly related to the chemical
analysis of the material than a series of readings on a certain entity.
Errors resulting from uneven surfaces and the inherent variation
due to the heterogeneity of samples, both referred to above, could have given rise
to falsely high bireflectance values for such low rank coals. For this reason
only maximum reflectance determinations were made. .
Both reflectance determinations and chemical analysis indicate an
extremely low rank for these samples. Although they should be classified as lignites
on the basis of their reflectances and carbon contents, their hydrogen contents are
unusually low even for sub-hydrous lignites so that these samples would lie well
apart from Seylerts coal band. However, coals with such an anomolous carbon-
hydrogen relationship have been previously recorded in Queensland.

DISCUSSION.
Spore units J5-6
Microfloras belonging to units J5-6 are known from the upperBirkhead Formation, Westbourne Formation and Hooray Sandstone in the easternEromanga Basin (Evans 1966b,d). Recent palynological information from theSurat Basin has led to a subdivision in the interval of these units and aredefinition of unit J6 (Burger 1968). The vertical range of the unit includesthe upper part of the Gubberamunda Sandstone and the Orallo Formation.
Undifferentiated J5-6 microfloras were recognized in Tambo 5 fromthe Hooray Sandstone (core 5) and the Westbourne Form&tion (core 9). Poorspore recovery, due to unfavourable fossilization conditions prevents the positiveidentification of J6.
Unit J5 was recognized in the Westbourne Formation of Jericho No.9 (cores 4, 5) and the basal Hooray Sandstone of Jericho No. 9 (core 3) andAugathella No. 3 (core 14).
Spore units K1a-b
The earliest Kla microfloras are recorded from the uppermostOrallo Formation in the Surat Basin (Burger 1968) unit Kla extends upwards ashigh as the base of the marine section of the Blythesdale Formation. BasalKI microfloras are recorded from the Hooray Sandstone in the eastern EromangaBasin ( Evans 1966-b).
'Undifferentiated Kla-b microfloras are identified, from the Hooray Sandstoneand overlying Marine Cretaceous in Tambo No. 5 and Augathella No. 3. Again,insufficient spore recovery prevents the positive recognition of unit K1a. UnitK1b however is recognized in the basal Marine Cretaceous from Augathella No. 3(core 1, sample 4383). The associated microplankton assemblage indicates theDingodinium cerviculum Dinofiagellate Zone. The presence of Cabelosporites stylosus in this microflora,,together with some microplankton species (Canningian. sp. Fvans 1966-e, p. 19; possibly also of Micrhystridium sp.) forms a combinationwhich is known only from the marine Mimi Member, of the Blythesdale Formation(Evans 1966-e; Burger 1968).
Spore units K2
The spore zonation in the K2 units, beginning with the first appearanceof 222-120.2na_Rmalaa (Evans 1966-d) is at the present time being studied inmore detail in the light of recent spore information obtained from the centraland northern Eromanga Basin.
Although C4Raradoxa was not encountered in the samples from Tambo No.6, its earliest occurrence coincided approximately with the base of theOdontochitina operculata Zone ( Evans 1966-e), and as Such the K2 unitsare thought to be represented in the nicrofloras of TambO.No. 6. Rare sporesdescribed by Dettmann (1963) from her Paradoxa Assemblage and recovered fromcore 1 (sample 4379), together with 0. operculata, strongly suggests a basal K2age for the microflora of this sample.
-3-
Tambo No. 6 cores 1 and 2 are tentatively attributed to the ToolebucLimestone, but certain characteristics of the microplankton succession, alsoobserved by Evans in the Julia Creek sheet area (Evans 1962) and later recognisedin other parts of the Eromanga Basin, might also point to the lowermost AllaruMudstone.
Adgathella No. 4 core 2 contains, besides Coptospora paradoxa,various types of angiospermous pollen grains in quantities unknown from lowerWinton and older formations (Burger, in prep.). Identical microfloras werealso recovered from the Winton Formation in W.O.L. Warbreccan Nos. 1 and 2 wellsand provisionally attributed, to the Upper Cretaceous (Cenomanian? See Evans 1966-c).
CONCLUSIONS.
Based on combined spore and microplankton criteria mentioned abovean upper and lower age limit can be given to the boundaries of the Hooray Sandstone,at least in the eastern part of the Eromanga Basin. Correlation with theUpper Jurassic to Lower Cretaceous formations in the Surat Basin appears to resultin the picture shown in Table 2. Palynological studies in the
LONGREACH - TAMBO- TAROOM sheet areas (Evans 1966-b) resulted in an almost
identical correlational scheme.
There are indications, based on vertical spore distribution, that thecontact between the lower and upper Hooray Sandstone should be correlated with somelevel in the upper part of the Blythesdale Formation.
At the present time palynological criteria for the identificationof the Upper Cretaceous in Australia are neither clearly defined, nor supportedby any other means of dating. Upper Cretaceous palynology is being studiedin detail at the University of Queensland by Drs. G. Playford and M.E. Dettmann.
Palynological reports of a great upsurge of Angiosperms in lowermostUpper Cretaceous microfloras throughout the world might prove to be valuablein subdividing the Cretaceous in Australia on the basis of the fraction ofAngiospermous pollen grains in the microfloras.

BL. TAMBO 8:-
Commenced in Triassic Dunda Beds and entered the Rewan Formation.Little of the two cores from the hole was suitable for examination. All samplesexamined were unfossiliferous.
BER TAO 9:-
Commenced in Permian Black Alley Shale and entered the PeawaddyFormation. Two samples were examined:
Core 1, 93 ft 6 in. - 94 ft Black Alley Shale.
An abundant yield of spores, pollen and occasional algae (see appendedlist). Spinose acritarchs were not observed. The variety of spores relative topollen is suggestive of a P3d rather than P4 age, in keeping with the regional ageof the Black Alley Shale. However, the lack of acritarchs precludes firmidentification of this zone. The lack of acritarchs contrasts strongly with theBlack Alley Shale intersected by the nearby B.M.R. Tambo No. 1 CH which in core3, at 161 ft 10 in. contained abundant Veryhachium sp. 3, the diagnosticcomponent of unit P3d.
Core 2, 163 ft 2 in. Peawaddy Formation.
Spores and pollen were relatively common but diluted with abundantmicrinitic material. No acritarchs could be seen. The spores (listed below)confirm a Stage 5 (P3b-4) age for the Peawaddy Formation on TAMBO.
BER JERICHO 4:-
Commenced in Colinlea and entered Joe Joe Formation. Samples weretaken from the Joe Joe Formation at:
MFP 4605^Core 1,^213 ft.NFP 4606 Core 2,^221 ft.
The microflora in both samples was relatively abundant andcharacteristic of stage 2 (see appendix).

BMR JERICHO 6:-
Passed from Quaternary into Joe Joe Formation. One sample wasexamined MFP 4613 Core 1 162 ft 0-6 in. Only a moderate yield of spores wasobtained which could fit into Stage 1. Further examination for more definitivespecies is warranted. The core was remarkable for its content of wellpreserved Rhacopterid pinnule fragments with cuticle intact which awaitfurther examination.

Cores from nine wells drilled in the Eromanga Basin during 1966
were submitted for petrophysical testing in the Petroleum Technology laboratory.
The results of testing are incorporated in the accompanying tableS.
Fluid saturation determinations were made only if the freshly broken
core segments exhibited fluorescence or if a positive acetone test was obtained
from the finely divided material.
All samples were subjected to a simple phosphate test using an
acid ammonium molybdate solution. Only one sample gave a positive reaction
viz. Adavale Scout No. 1, core 4, 113'6" - 11411".In some cases the core segments were found to consist of small
fragments from which regular shapes for permeability determinations could not
be cut; these are recorded in the table as "N.D." (not determined).
Petroleum Technology Laboratory, Bureau of Mineral Resources, Geology and Geophysics, Canberra
CORE ANALYSIS RESULTS
NOTE:- (i) Unless operwise stated, the porosities and permeabilities were determined on two ., small plugs (V&H) cut at right angles from the core.
Ruska porosimeter and permeameter were used with, air at 30 p.s.i.g. and dry nitrogen • respectively, as the saturating and flowing media.(11) Residual oil and water saturations were determined using soxhlet type apparatus. (iii) Acetone test precipitates are recorded as nil, trace, fair,
strong or very strong.
