GSWA Boologooro 1 well completion report (interpretive)

GSWA Boologooro 1 well completion report (interpretive), Southern Carnarvon Basin, Western Australia by D. W. Haig1, A. J. Mory2, M. Dixon1, J. Backhouse3, R. J. Campbell1, K. A. R. Ghori2, R. Howe3, and P. A. Morris2

Abstract GSWA Boologooro 1 is a stratigraphic hole drilled in 2001 at 24°19'27.3"S, 113°53'53.3"E on the Gascoyne Platform in the Southern Carnarvon Basin, and continuously cored from 51.4 m to a total depth of 383.8 m. The drillhole intersected 32 m of alluvium, the Miocene Trealla Limestone, and the Cretaceous Korojon Calcarenite, Toolonga Calcilutite, Haycock Marl, Gearle Siltstone, and uppermost Windalia Radiolarite. The underlying Muderong Shale and Birdrong Sandstone unconformably overlie the Upper Devonian Gneudna Formation in an adjacent water bore. The core yielded foraminifera, nannofossils, and palynomorphs, which provide excellent palaeontological control for the Cretaceous section. The Frasnian Gneudna Formation consists mainly of limestone and mudstone, probably deposited in an open innerneritic environment. The overlying Barremian Birdrong Sandstone, Barremian – lower Aptian Muderong Shale, upper Aptian – lowermost Albian Windalia Radiolarite, and lower Albian to Cenomanian Gearle Siltstone record broadly increasing water depths (inner to mid-neritic zone; 50–100 m). Foraminifera indicate distinct increases in palaeobathymetry in the lower Albian part of the Gearle Siltstone and in its Cenomanian section. Alternating carbonaceous mudstone and clayey calcilutite of the Turonian Haycock Marl is probably conformable on the Gearle Siltstone. The transition between these two units is marked by black shale that probably represents the Cenomanian–Turonian boundary oceanic anoxic event (OAE2). The overlying Toolonga Calcilutite consists mostly of pelagic carbonate facies bound by two major erosional surfaces, and contains a relatively thin middle Coniacian to Santonian interval, overlain by a thick Campanian section. The uppermost Campanian to lower Maastrichtian Korojon Calcarenite is the youngest of the Cretaceous carbonate units preserved in Boologooro 1, and it underlies the Miocene Trealla Limestone. The environment of deposition of the Haycock Marl, Toolonga Calcilutite, and Korojon Calcarenite was probably middle to outer neritic (about 100–150 m depth). The petroleum potential of the Cretaceous section in Boologooro 1 is limited by its immaturity. All but one of the Cretaceous samples are organically rich with a total organic content range of 1.3 to 18.4%, a potential yield of 0.5 – 51.2 mg/g rock, and dominated by oil- and gas-generating type II kerogen. The organically richest sample from the Gearle Siltstone contains type II kerogen close to type II/III; all other samples have poor to fair gas-generating potential. Cuttings from the Gneudna Formation show poor petroleum-generating potential. KEYWORDS: diamond drilling, Miocene, Cretaceous, Devonian, stratigraphy, biostratigraphy, palaeobathymetry, palynology, foraminifera, nannofossils, geochemistry.

Introduction The Geological Survey of Western Australia’s (GSWA’s) Boologooro 1 is a stratigraphic drillhole 66 km northnortheast of Carnarvon on Boologooro Station. The drillhole is 19 km due west of Boologooro Homestead, which lies 70 km north of Carnarvon via the North West Coastal Highway (Fig. 1). The nearest petroleum and stratigraphic drillholes are Grierson 1–3, 16 km to the northwest; Quobba 1, 45 km to the west; and Cape Cuvier 1, 50 km to the west-northwest (Fig. 2). To the east

and cuttings from the Western Australian Water and Rivers Commission (WRC) bores drilled as part of their artesian bore refurbishment program (see WRC website at http://www.wrc.wa.gov.au). The position of the hole in relation to geological structure is uncertain because the nearest seismic section (B72-01L) lies 20 km to the south. No signs of hydrocarbons were encountered in Boologooro 1, and there are only minor indications of mineralization.

University of Western Australia, as part of an Australian Research Council project on the Cretaceous. This joint project involved two other drillholes, GSWA Edaggee 1 and GSWA Yinni 1, 120 and 215 km to the south-southeast respectively (Mory and Dixon, 2002a,b; Dixon et al., 2003a,b). Boologooro 1 was abandoned when sticky carbonaceous clays in the Gearle Siltstone and cavings from the basal part of the alluvium considerably slowed progress. The hole was not logged at the time of abandonment because the logs from the water bore 40 m to the north, which was logged during the WRC bore refurbishment program, are adequate to correlate this section. Information on the section below 383.8 m from this water bore has been incorporated into this report.

The primary objective of Boologooro 1 was to continuously core the Cretaceous section to enhance the understanding of the age and sedimentology of this section. Drilling was undertaken in collaboration with the 2

Quaternary sediments The uppermost section of Boologooro 1 (0–32 m) comprises red to brown, fine- to medium-grained, loose sand and rare clay.

Trealla Limestone Summary The Trealla Limestone in Boologooro 1 is a miliolid foraminiferal limestone (mainly packstone and wackestone) that contains larger benthic foraminifera characteristic of Tf1–2 Letter Stage of the Indo-West Pacific Region. The limestone is of late Early Miocene or Middle Miocene age and lies unconformably on Cretaceous strata. Only cuttings were collected from this unit.

Lithostratigraphy The interval from 32 m to at least 49 m is placed in the Trealla Limestone. Limestone cuttings from the interval 32–38 m in the adjacent water bore include a pale-orangebrown packstone with foraminifera and coralline algae as the main components. The foraminifera include abundant smaller and larger (complex) porcellaneous species of the Order Miliolida. In cuttings from the interval 45–48 m, recrystallized sugary limestone is the most common rock type, with less common fine-grained algal–foraminiferal grainstone and packstone.

Regional structural setting Boologooro 1 was drilled in the central part of the Gascoyne Platform (Fig. 2) within the Southern Carnarvon Basin (Hocking et al., 1994). The Gascoyne Platform is an area of up to 5000 m of faulted and folded Ordovician– Devonian strata (Fig. 3) that became structurally elevated in the mid-Carboniferous whereas deposition in adjacent sub-basins continued at least into the mid-Permian (Iasky and Mory, 1999, fig. 4). The Palaeozoic section is covered by typically flat lying Cretaceous and, within the Woodleigh impact structure, Lower Jurassic strata (Iasky and Mory, 1999, fig. 4) that structurally are completely unrelated to the Palaeozoic sub-basins.

Chronostratigraphy The Tf1–2 Letter Stage foraminifera recovered from this unit (Appendix 1), equate to the mid-N6 to N14 planktonic foraminiferal zones according to the correlations of Adams (1984) of late Early Miocene to Middle Miocene age (11– 18 Ma according to the chronometric scale of Berggren et al., 1995).

Seismic control in the region is sparse and of poor quality (Iasky and Mory, 1999, fig. 1; Iasky et al., 2003, fig. 4), so the drillhole was located primarily as a stratigraphic test on the basis of data from the adjacent artesian bore. The nearest seismic section (B72-01L), 20 km to the south, suggests that Boologooro 1 was drilled over a broad syncline in the Palaeozoic section overlain by mostly flat lying Cretaceous strata. Correlations with nearby bores

Regional correlations The miliolid limestone facies is similar to the upper part of the Trealla Limestone in its type section at Mount Lefroy on Cape Range (following the descriptions of 4

in the >150 µm sediment fraction (Fig. 6; Appendix 1). Above 73.6 m, some of the delicate thin-walled foraminiferal tests may have been selectively dissolved, and foraminiferal preservation is variable. Preservation of foraminifera is excellent below 73.6 m. Nannofossil preservation is poor to moderate throughout the formation (Appendix 4), whereas palynomorph preservation is excellent (Appendix 2).

Chaproniere 1975, 1984). This facies is also represented throughout the (>19 m-thick) section of the formation exposed in the Giralia Anticline (Smith, 1989), and in outcrops as far south as Yaringa Station about 200 km south of Boologooro 1.

Depositional environment The foraminiferal assemblage includes abundant soritids, peneroplids, and smaller miliolids (Appendix 1), and indicates that the Trealla Limestone was deposited in a very shallow marine environment of normal or slightly elevated salinity. Water depths may have been just a few metres, and water temperatures were warm (above 18°C; Murray, 1991) based on the distribution of analogous modern foraminifera and the absence of planktonic foraminifera.

Chronostratigraphy The Korojon Calcarenite in Boologooro 1 probably spans the Campanian–Maastrichtian boundary (Fig. 6) as recently defined by Odin (2001) and ratified by the International Commission on Stratigraphy. Of the 12 datum levels selected by Odin (2001) to define the boundary, two are in Boologooro 1. About 10 m below the boundary stratotype at Tercis, France, there is a transition among the benthic foraminifera Bolivinoides from types with a dominance of four sutural lobes to those with five lobes. The highest occurrence of the dinoflagellate Samlandia mayi is just above the boundary stratotype. In Boologooro 1, S. mayi is at 80.9 m and fourlobed Bolivinoides sp. at 80.1 m, whereas five-lobed forms (attributed to B. australis) predominate above 68.2 m (Appendix 1). This suggests that the boundary lies somewhere between 68.2 and 80.1 m. Nannofossil Zone CC23a has been identified between 56.76 and 77.2 m (Appendix 4). In the Tercis section, Gardin et al. (2001) showed that Zone CC22 is present below the stratotype boundary and CC23a lies above this level. The boundary stratotype lies in an interval in which the nannofossil zonation is uncertain.

Korojon Calcarenite Summary The Korojon Calcarenite, cored between 51.4 and 81.2 m, is an interval of mainly grey wackestone that lies between two major erosional surfaces. In part, it includes (Fig. 6) nannofossil zone CC23a; planktonic foraminiferal zones KPF4, KPF5 and an unzoned interval above the lowest occurrence of Rugoglobigerina; benthic foraminiferal zones KBF1–3 and an unzoned interval above the lowest occurrences of Anomalina bembix and Bulimina cf. prolixa; and the dinoflagellate I. korojonense Zone. The Campanian–Maastrichtian boundary lies in the 77.2 – 80.1 m interval between calcareous nannofossils of the CC23a Zone above and four-lobed specimens of the benthic foraminifera Bolivinoides sp. below.

In Boologooro 1, the Campanian–Maastrichtian boundary probably lies between 77.2 m and 80.1 m, and further nannofossil work on this interval is required for more precise positioning of the boundary. Following the correlations of Gardin et al. (2001), the presence of Zone CC23a above 77.2 m suggests that this section belongs to the lower part of the Lower Maastrichtian. The presence of four-lobed Bolivinoides sp. at 80.1 m, and the stratigraphic correlation of this level to above the highest occurrence of Heterohelix semicostata in UWA Cardabia 1 (Appendix 1), suggests that this level belongs to the upper part of the Upper Campanian.

Lithostratigraphy The uppermost part of the formation consists of heavily weathered white wackestone with ‘interbeds’ (probably vug infills) of yellow to green quartz sandstone, sandy mudstone, and claystone. Between 55.4 and 73.6 m the formation consists largely of iron-stained light-grey wackestone, which was probably part of a mid-Cainozoic (pre-Trealla Limestone; post-Middle Eocene) weathering profile. Distinctive beds within this section include thin coquinite composed of small bivalves between 58.6 and 59.8 m, and wackestone intervals at 64–66 m and 69–71 m in which thick-shelled Inoceramus fragments are concentrated.

Regional correlations The type section of the Korojon Calcarenite is in the Giralia Anticline along C–Y Creek (Condon et al., 1956). In Appendix 1, the succession of selected foraminiferal datum levels (for regional time correlation) in Boologooro 1 is compared to the equivalent succession in UWA Cardabia 1, which is about 15 km south of the type section in the Giralia Anticline and 180 km north of Boologooro 1. Cardabia 1 contains the Korojon Calcarenite from 53.6 to 90.8 m. The succession of datum levels above 77 m in Cardabia 1 is very similar to the succession found in Boologooro 1 above 77 m (Appendix 1). This indicates very similar rates of sedimentation between these sites. In Cardabia 1 the lowest occurrence of the benthic Bulimina cf. prolixa is at 77.4 m and the planktonic Heterohelix semicostata between 77.4 and 81.7 m. In Boologooro 1

The lower part of the Korojon Calcarenite (from 73.6 to 80.6 m) is a pale-grey to pale-green-grey wackestone containing common scattered Inoceramus shell fragments. The basal bed of the Korojon Calcarenite between 80.5 and 81.2 m is a wackestone that includes abundant granule- to large pebble-sized phosphatic nodules, rare barite nodules, and common small cube-shaped Inoceramus fragments. Foraminifera and Inoceramus prisms are the main constituents of the sand fraction of the wackestone. The abundance of planktonic foraminifera is variable, but is commonly less than 20% of the total foraminiferal count 8

Bulimina cf. prolixa appears down to the lowest sampled level within the Korojon Calcarenite 1 (at 80.9 m), but H. semicostata has not been found. This suggests that the lower part of the Korojon Calcarenite in the Giralia Anticline (namely the interval 77–90 m in UWA Cardabia 1) is missing from Boologooro 1.

foraminiferal biofacies, water depths were probably in the shallow part of the outer neritic zone (Appendix 1). Changes in dominant species among the benthic foraminiferal assemblages (Appendix 1) suggest variation in bottom-water conditions. These changes are difficult to interpret based on a single stratigraphic section, but may involve slight fluctuation in dissolved oxygen and temperature levels on the sea floor.

Depositional environment Palaeobathymetric trends interpreted from the foraminiferal succession (Appendix 1) are summarized in Figure 6. The pelagic nature of the sediment suggests that deposition occurred at some distance from the shoreline. Based on the percentage of planktonic foraminifera in the unweathered section below 73.6 m and the benthic

the lower boundary is uncertain, and requires further study to resolve. The formation includes (Fig. 7), in descending stratigraphic order, nannofossil assemblages assigned to Zones CC21, CC20, CC18b–19, CC18b, CC18a, CC17, CC15–16, CC14; planktonic foraminiferal Archaeoglobigerina cretacea Zone, Marginotruncana marginata Zone, and Heterohelix papula Zone; 21 benthic foraminiferal datum levels useful for regional time correlation within the basin; and the I. korojonense, X. australis, N. aceras, I. cretaceum, O. porifera, and C. striatoconum dinoflagellate zones.

assemblages across the boundary between the Korojon Calcarenite and Toolonga Calcilutite indicate that it is a disconformity that spans a substantial time interval. According to the nannofossil zones identified in Appendix 4, this interval incorporates all or part of Zone CC22/UC (representing part of the Upper Campanian). The CC20 to CC18a interval between 126.9 and 230.10 m correlates to the Lower Campanian. As in Edaggee 1 (Dixon et al., 2003b), the lowest occurrence of Aspidolithus parcus parcus is used to position the Santonian–Campanian boundary in Boologooro 1. Based on this criterion, the boundary lies within the interval 230.1 – 235.0 m. This is above the lowest occurrence of the benthic foraminifera Bolivinoides strigillata and well above the lowest occurrences of Anomalinoides eriksdalensis and Cibicides excavata (see Appendix 1, Table 1.6). In Edaggee 1 the lowest occurrence of A. parcus parcus is close to the lowest occurrences of Cibicides excavata, and apparently below the lowest occurrence of Osangularia sp. In Boologooro 1, however, the lowest occurrence of Osangularia sp. is about 20 m lower than that of A. parcus parcus. Therefore, the A. parcus parcus lowest occurrence may be diachronous with respect to the benthic foraminiferal datum levels between these sections.

Lithostratigraphy The Toolonga Calcilutite, between 81.2 and ?280.2 m in Boologooro 1, is composed mainly of dark-green, variably bioturbated, clayey nannofossil and foraminiferal wackestone (calcilutite). Distinctive intervals within an otherwise lithologically uniform unit include thin (150 µm sediment fraction (Fig. 7; Appendix 1), show that deposition occurred near the transition between the midneritic and outer neritic zones (water depths probably between about 80 and 150 m). Maximum water depths, as recorded in the Boologooro 1 section, were reached during the early Late Campanian, Early Campanian (around the lower part of Zone CC18b–19), Late Santonian, and the oldest part of the Coniacian (Fig. 7).

Regional correlations In Boologooro 1 the Haycock Marl is thinner (3.1 m) than in Edaggee 1 (7.6 m; Dixon et al., 2003b). The stratigraphic range of the formation (nannofossil zones UC6b–7) in Boologooro 1 is also more restricted than in Edaggee 1 (zones UC6a–9). Outcrop sections of the unit north and south of Boologooro 1 (at C–Y Creek and on Murchison House Station respectively) are less than 1 m thick (Howe et al., 2000; Haig, 2002).

Depositional environment Regional correlations suggest that the Haycock Marl was deposited as a widespread unit on a low-gradient continental shelf, across much of the Southern Carnarvon Basin. The very low relative abundance (150 µm sediment fraction. These trends imply that the deepest water facies, which was deposited within the outer neritic zone (water depths of 100–200 m), is probably at around 282.5 m in the section.

Haycock Marl Summary The Haycock Marl is a thin (3.1 m-thick) unit preserved beneath an erosional surface (at 280.2 m), and defined at the base by a black laminated claystone in sharp contact at 283.3 m with an underlying bioturbated claystone. The formation contains the lowest occurrence of Cretaceous wackestone (calcilutite) facies in Boologooro 1, and includes (Fig. 8) the nannofossil upper CC10b–11 Zone, the planktonic foraminiferal Helvetoglobotruncana helvetica Zone, and the dinoflagellate P. infusorioides Zone.

The cycles of alternating carbonaceous clay and bioturbated calcilutite identified in Edaggee 1 (Dixon et al. 2003b) are represented in Boologooro 1 by planar laminated black claystone units at the top and bottom of the formation, separated by a calcilutite unit. The black shales probably indicate anoxic events.

Lithostratigraphy In Boologooro 1 the Haycock Marl lies between 280.2 and 283.3 m, and consists of upper and lower black laminated claystone beds (each 20 specimens recovered indicating ‘abundant’; 10–20 specimens being ‘common’; and 150 µm) Organic-cemented agglutinated (%) Calcite-cemented agglutinated (%) Hyaline (Lagenida) (%) Hyaline (Buliminida) (%) Hyaline (Rotaliida) (%)

Important aspects of the foraminiferal succession found in the >150 µm sediment fraction in the interval 53.9 – 80.9 m in Boologooro 1. The benthic foraminiferal biofacies are defined by dominant species in Table 1.2

the interval 54.1 – 61.3 m in Cardabia 1 at the top of the Korojon Calcarenite and below the contact with the Miria Formation (which belongs to the planktonic foraminiferal Abathomphalus mayaroensis Zone). In Cardabia 1 the highest occurrence of Globotruncana linneiana coincides with an isolated occurrence of Bolivinoides draco, the highest occurrence of Bolivinoides australis, and a marked decrease in abundance of Bulimina cf. prolixa.

1998) on the Exmouth Plateau, and to part of the Globotruncanella havanensis Zone (Huber, 1992; Petrizzo, 2001) in the Austral Realm. Index species that define the boundaries of Tethyan planktonic foraminiferal zones (Nederbragt, 1991; Robaszynski and Caron, 1995) are absent from Boologooro 1. However, based on the occurrences of Pseudotextularia intermedia and Gublerina cuvillieri in Boologooro 1, and of Gublerina cuvillieri and Abathomphalus mayaroensis in Cardabia 1, the Boologooro 1 section is probably equivalent to part of the Tethyan Gansserina gansseri Zone of Caron (1985). With respect to the planktonic foraminiferal zonation of the Tercis les Bains section in France that includes the Campanian–Maastrichtian Boundary Stratotype (Odin, 2001), Gublerina acuta, a precursor of G. cuvillieri according to Nederbragt (1991),

In terms of the North West Shelf KPF zonation based on planktonic foraminifera outlined by Campbell et al. (2002), most of the interval may be equivalent to part of the KPF3 zone. Based on its occurrence above the lowest occurrence of Heterohelix rajagopalani and probably below the lowest occurrence of Abathomphalus, the Boologooro 1 interval may correlate to part of the Heterohelix rajagopalani Zone (Wonders, 1992; Zepeda, 24

recorded from the Tercis les Bains section, its ancestor B. miliaris is in an approximately 60 m-thick section that spans the Campanian–Maastrichtian Boundary Stratotype (Tronchetti, 2001). Tronchetti (2001) also suggested that an evolutionary trend was present among Bolivinoides in the Tercis les Bains section. This involved a progressive increase in the number of sutural lobes on adult chambers, from 3–4 lobes in specimens from the interval about 105 to 25 m below the boundary stratotype to 4–6 (dominantly 5) lobes in specimens above the boundary. The latter included morphotypes compared by Tronchetti (2001) to B. australis that represented the youngest occurrence of Bolivinoides in the Tercis les Bains section. Bolivinoides australis with 6–7 sutural lobes per adult chamber is in the lower part of the interval 53.9 – 60 m in Boologooro 1. In the English Chalk, Hart et al. (1989) used the total range of B. draco to define the highest of their Cretaceous benthic foraminiferal zones (UKB.22 Zone), and showed its range as being approximately equivalent to that of the planktonic species Abathomphalus intermedia and ‘Rosita patelliformis/contusa’. The Bolivinoides occurrences in Boologooro 1 (and at equivalent levels in Cardabia 1) therefore support the suggestion based on planktonic foraminifera that the interval 53.9 – 60 m in Boologooro 1 lies above the Campanian–Maastrichtian boundary.

is confined to the Rugoglobigerina scotti Zone of the Lower Maastrichtian (Arz and Molina, 2001). Globotruncanita stuarti ranges upward from the Rugoglobotruncana rotundata Zone of Arz and Molina (equivalent to the Globotruncanella havanensis Zone as used by Odin, 2001) about 23 m below the Campanian–Maastrichtian boundary stratotype. Globotruncana linneiana ranges upward to the top of the Tercis les Bains section (at about 59 m above the boundary stratotype and well above the lowest occurrence of Contusotruncana contusa, which is close to the boundary (Arz and Molina, 2001; Ion and Odin, 2001; and Odin et al., 2001). Contusotruncana contusa is not recorded from the Boologooro 1 section or from equivalent levels in the Korojon Calcarenite in Cardabia 1, but it is associated with A. mayaroensis in the overlying Miria Formation in Cardabia 1. Despite the discrepant ranges of C. contusa in the Southern Carnarvon Basin and Tercis les Bains sections, the available planktonic foraminiferal datums suggest that the interval 53.9 – 61.1 m in Boologooro 1 lies above the Campanian–Maastrichtian boundary. Among the benthic foraminifera in the interval 53.9 – 61.1 m in Boologooro 1, the presence of Bolivinoides draco at 60 m appears to be the most significant datum for global correlation. Although this species was not 25

The planktonic species at 280.0 m do not include zonal indices. The presence of common Marginotruncana pseudolinneiana suggests a level no lower than the middle part of the Helvetoglobotruncana helvetica Zone based on the distribution patterns of this species found by Petrizzo (2000) in Exmouth Plateau sections.

In Exmouth Plateau sections, Petrizzo

The assemblage at 280.0 m may be affected by reworking from underlying units, and is just above a probable erosion surface with an accumulation of phosphatic nodules and a sharp lithological contact. 43

(2000) recorded the highest occurrence of Dicarinella hagni within the Helvetoglobotruncana helvetica Zone, although elsewhere it is known from higher levels in the Turonian (Caron, 1985).

Praebulimina reussi, Pyramidina sp., and Tappanina cf. laciniosa are abundant to common (Table 1.6). Tappanina cf. laciniosa is not known from lower samples.

Benthic species dominate the foraminiferal assemblages (Table 1.6), and include abundant Rotaliida (50–65% of >150 µm fraction), and common calcitecemented agglutinated foraminifera (27–43%). Among the benthic types, Lingulogavelinella cf. convexa, Gaudryinopsis filiformis, Cassidella? tegulata, and Tappanina cf. laciniosa range no higher than this interval (Table 1.6; Fig. 1.5).

282.8 – 283.1 m, unzoned This interval includes a black laminated shale below 282.9 m, and a dark-grey bioturbated unit above this level. Foraminifera are sparse, with only very rare Lenticulina muensteri observed at 283.1 m, and mainly organiccemented agglutinated types (viz. Ammodiscus glabratus, Bathysiphon sp., and Gaudryinopsis filiformis) and rare planktonic Globigerinelloides ultramicra recovered from 282.8 m.

283.3 – 304.1 m, Textulariopsis spp. Benthic Zone (Marssonella Association) 283.9 – 304.1 m, upper part of Palustrella kurillinensis Benthic Zone (Ammobaculites Association)

This zone is defined by the total range of Helvetoglobotruncana helvetica (following Petrizzo, 2000). Planktonic foraminifera overwhelmingly dominate the foraminiferal assemblage (Table 1.6; forming greater than 92% of >150 µm fraction), and include abundant Whiteinella spp., as well as common Globigerinelloides ultramicra and Heterohelix morphotypes transitional between H. moremani and H. globulosa. The other planktonic species, including keeled Dicarinella and Helvetoglobotruncana, are rare at this level.

Among the benthic foraminifera (Table 1.7) in the interval 283.3 – 304.1 m are elements of two faunal associations. The microfauna is transitional between the Ammobaculites and Marssonella Associations as defined by Haig (1979a; Haig and Lynch, 1993). The Textulariopsis Zone is defined by the total range of closely related T. sp. W1, T. sp. W2, and T. sp. W3 in association with other calcareous agglutinated and hyaline benthic species characteristic of

Benthic foraminifera are very rare in the >150 µm sediment fraction. However, in the 63–150 µm fraction small benthic species, including the buliminids 45

The Palustrella kurillinensis Zone (formerly named the Textulariopsis? kurillinensis Zone in Edaggee 1; Dixon et al. 2003) is defined by the total range of this species in association with other organic-cemented agglutinated species characteristic of the Ammobaculites Association (Haig, 1979a).

Within the interval, planktonic foraminifera are typically rare with species of Hedbergella dominating (Table 1.7; Fig. 1.6). One specimen of Rotalipora sp.

Among the common benthic foraminifera, the lowest occurrence of Dorothia conicula coincides with the lowest occurrence of Textulariopsis at the base of this interval; Stensioeina? sp. has its lowest occurrence at 288.1 m, and the lowest occurrence of Lingulogavelinella cf. convexa is at 283.3 m. The highest occurrence of Berthelina intermedia is at 287.1 m, and the highest occurrence of Lingulogavelinella indica at 283.9 m.

dominate the assemblages; minute calcareous hyaline types (rotaliids, buliminids, and lagenids) are abundant in the 63–150 µm sediment fraction at some levels. Figure 1.6 shows datum levels that may be significant for local correlation.

377.8 m, unzoned; within range of Pleurostomella reussi This level contains a sparse benthic foraminiferal assemblage (Table 1.7) that includes rare organiccemented agglutinated species and few calcareous hyaline types (lagenids and buliminids). All species are known from the overlying zone, but only Pyramidulina cf. obscura is known in the underlying interval. The presence of Pleurostomella reussi is significant because it suggests that this level lies within the Albian.

305.1 – 347.1 m, lower part of Palustrella kurillinensis Benthic Zone (Ammobaculites Association) 341.1 – 347.1 m, upper part of Blefuscuiana sp. Planktonic Zone The Palustrella kurillinensis Zone (formerly named the Textulariopsis? kurillinensis Zone in Edaggee 1; Dixon et al. 2003) is defined by the total range of this species in association with other organic-cemented agglutinated species characteristic of the Ammobaculites Association (Haig, 1979a). An isolated occurrence of Blefuscuiana sp. at 341.1 m (Table 1.7) represents the highest record of this planktonic species in Boologooro 1, and defines the top of the Blefuscuiana sp. Zone.

378.6 – 382.0 m, Aaptotoichus pitmani Zone, within range of Lingulogavelinella cf. santoodnae The interval is marked by an absence of agglutinated foraminifera including the nominate species for the zone, but includes a moderately diverse calcareous hyaline benthic assemblage (Table 1.7). The main components are lagenid species with rare buliminids (Coryphostoma sp.), and abundant small-sized rotaliids (Gavelinella, Gyroidinoides, and Lingulogavelinella). The interval records the transition from Lingulogavelinella cf. santoodnae (with slightly evolute spiral side) to Lingulogavelinella santoodnae (with involute spiral side) that was recorded in the Aaptotoichus pitmani Zone from the upper Doncaster Member (Upper Aptian) of the Eromanga Basin in Queensland (Haig, 1979b, 1982; Campbell and Haig, 1999)

In the interval 305.05 – 347.10 m, organic-cemented agglutinated species dominate the foraminiferal assemblages (Table 1.7), and are the only foraminifera found between 305.05 m and 328.05 m. Below 328.05 m, hyaline benthic species (calcitic lagenids, buliminids, and rotaliids, and aragonitic robertinids) are variably present. The biofacies succession based on benthic assemblages is shown on Figure 1.6, with the dominant species defining each biofacies listed on Table 1.8. Benthic datum levels that may be significant for regional correlation are shown on Figure 1.6. In terms of global correlation, the highest occurrence of Epistomina spinulifera is within the lower part of the M. inflatum Ammonite Zone in the Upper Albian of the English succession (Hart et al., 1989).

Palaeobathymetric zonation The palaeobathymetric trends interpreted from the foraminiferal succession in Boologooro 1 (Figs 6–9) are based on: • analogy to the distributions of extant genera and of similar morphotypes among modern species (following, for example, Murray, 1991, Pflum and Frerichs, 1976); • percentage of planktonic tests in the total assemblage and their test size (following for example, Grimsdale and van Morkhoven, 1955; Murray, 1976); • Late Cretaceous palaeoslope distribution models established for the Atlantic margin of North America by Nyong and Olsson (1984), Olsson and Nyong (1984), and Sikora and Olsson (1991); • Cretaceous bathymetric zonations established by analyses of facies successions by, for example, Birkenmajer and Gasinski (1992), Campbell and Haig (1999), Haig and Lynch (1993), Haynes (1981), Koutsoukos and Hart (1990), Koutsoukos et al. (1991), Kuhnt and Kaminski (1990), Schwentke and Kuhnt (1992), Sliter and Baker (1972), Van Morkhoven et al. (1986).

348.1 – 377.1 m, Eomarssonella crespinae Benthic Zone (Ammobaculites Association) 348.1 – 376.1 m, Blefuscuiana sp. Planktonic Zone The Eomarssonella crespinae Zone is here redefined from the lowest occurrence of E. crespinae to the lowest occurrence of Palustrella kurillinensis in the Ammobaculites Benthic Association. Based on planktonic foraminifera, the Blefuscuiana sp. Zone is defined by the range of this species below the lowest occurrence of muricate Hedbergella. The top of the Blefuscuiana sp. Zone (based on the highest occurrence of Blefuscuiana sp. in Boologooro 1) is recorded in the overlying Palustrella kurillinensis Zone. Table 1.7 records the species found in the zone. Organic-cemented agglutinated foraminifera typically 56

Changes in benthic biofacies (characterized in Tables 1.2, 1.4, and 1.8) although indicating environmental change, do not necessarily suggest major changes in water depth (summarized in Figs 6–9). The changes in benthic assemblage may be related to slight variation in temperature, salinity, dissolved oxygen, and food supply. Abrupt changes in benthic biofacies in the succession may represent abrupt environmental change or the positions of ‘hidden’ hiatuses.

Appendix 2

Palynology by J. Backhouse Backhouse Biostrat Pty Ltd, Wembley, Western Australia

148.1 – 235.0 m, Nelsoniella aceras Dinoflagellate Zone

Introduction Palynological results from Boologooro 1 are based on the samples and palynological zones listed in Table 2.1. In the two range charts (Tables 2.2 and 2.3), species are arranged by lowest occurrence. Only some samples in the middle to Lower Cretaceous intervals have been counted and are presented as raw counts (Table 2.2). Samples from the Upper Cretaceous interval have not been counted. A breakdown of spores and pollen is not presented because it does not contribute to the biostratigraphy, and dinocysts listed are only a selection of common forms and key species.

The lowest occurrence of N. aceras (235.0 m) marks the base of the zone, and the lowest occurrence of X. australis marks the top of the zone. This zone is particularly thick, although N. aceras is not present in most samples through the middle and upper parts of the zone. Several specimens are recorded at 148.1 m and, although it is possible that they are reworked, the absence of X. australis at this level and its lowest occurrence in the immediately higher sample supports the hypothesis that they are in situ. Australisphaera verrucosa and Impagidinium margaritiferum have their lowest occurrences in the upper part of the zone.

The zonation used is the microplankton scheme of Helby et al. (1987), which although somewhat dated still provides the only comprehensive zonation for the whole of the Cretaceous in the Australian region. Future work on Boologooro 1 and other wells in the area will eventually provide a refined zonal scheme. At present only a limited selection of samples has been examined, of which a few have been studied in great detail. When all samples have been exhaustively examined the ranges of some species listed in the range charts may change slightly. For this report emphasis has been placed on determining zone boundaries as accurately as possible.

236.9 – 248.1 m, Isabelidinium cretaceum Dinoflagellate Zone The lowest occurrence of I. cretaceum (248.1 m) marks the base of the zone, and the lowest occurrence of N. aceras marks the top of the zone. The generic epithet Isabelidinium is retained here for I. cretaceum until more details can be obtained on the morphology of this species. This zone and the underlying O. porifera Zone have been little studied to date in Boologooro 1. Nevertheless, this is a key biostratigraphic interval within which many significant Late Cretaceous species have their lowest occurrences.

Palynological observations and comments 80.9 – 114.2 m, Isabelidinium korojonense Dinoflagellate Zone

255.1 – 274.1 m, Odontochitina porifera Dinoflagellate Zone

The zonal assignment is based on the presence of I. korojonense and absence of Manumiella spp. in the higher samples. The diverse dinocyst assemblages at this level are not reflected in the current range charts. Samlandia mayi is in the highest sample, suggesting a correlation at this level with the Samlandia carnarvonensis Zone of McMinn (1988). Spores and angiosperm pollen are present in very low numbers.

The lowest occurrence of O. porifera (274.1 m) marks the base of the zone, and the lowest occurrence of I. cretaceum marks the top of the zone. Stephodinium australicum, Isabelidinium rectangulare, and Amphiadiadema denticulata have lowest occurrences at the base, or within the zone; and the small probable algal cyst, Fromea chytra, also has a lowest occurrence near the top of the zone.

275.9 – 277.9 m, Conosphaeridium striatoconum Dinoflagellate Zone

117.1 – 137.1 m, Xenikoon australis Dinoflagellate Zone

The lowest occurrence of C. striatoconum marks the base of the zone, and the lowest occurrence of O. porifera marks the top. The zone is less than 5 m thick, but is readily identified by the presence of the distinctive eponymous species. However, the ranges of C. striatoconum and O. porifera overlap in the next highest sample (274.1 m). By definition, this sample is placed in the O. porifera Zone.

The lowest occurrence of X. australis (137.1 m) marks the base of the zone, and the lowest occurrence of I. korojonense marks the top of the zone. This relatively short interval displays a high variety of dinocysts, many apparently undescribed. The presence of Diconodinium spp. at this level is thought to represent reworking. 59

GSWA Boologooro 1 well completion report (interpretive)

In Boologooro 1, Xenascus ceratioides, Balteocysta perforata, and Gillinia hymenophora appear at the base or within the zone.

378.2 m, Muderongia tetracantha Dinoflagellate Zone The highest occurrence of Diconodinium davidii marks the base of the zone, and the highest occurrence of Muderongia tetracantha marks the top. In Boologooro 1 the M. tetracantha Zone is present in only this one sample containing several specimens of M. tetracantha and lacking D. davidii. The interval assigned to this zone in Boologooro 1 is clearly very thin because samples approximately 0.5 m above and below belong in other zones.

278.9 – 288.1 m, Palaeohystrichophora infusorioides Dinoflagellate Zone The highest occurrence of Endoceratium ludbrookiae marks the base of the zone, and the lowest occurrence of C. striatoconum marks the top. Most cysts characteristic of the underlying D. multispinum and E. ludbrookiae zones are not recorded in the P. infusorioides Zone, or are seen only in the lowest samples. Litosphaeridium siphoniphorum ranges through the zone, though it is rare at the top, and Circulodinium distinctum appears in the upper part.

378.6 – 414 m, Diconodinium davidii Dinoflagellate Zone The lowest occurrence of Endoceratium turnerii marks the base of the zone, and the highest occurrence of Diconodinium davidii marks the top. However, the base of the zone is picked in an interval covered by cuttings samples, and therefore the base of this zone is effectively selected as the first sample above the highest occurrence of Muderongia australis or other indicator species for the M. australis Zone. The index species Ovoidinium striatum is only in the lowest sample, although heavy caving of dinocysts from higher levels may mask its range in Boologooro 1. The species was previously recorded as ranging from the middle to lower part of the D. davidii Zone (Riding and Helby, 2001), equivalent to the informal subdivisions 2biiib–2biiia of Foster (2001). Therefore, the lowest sample belongs in the middle to lower part of the D. davidii Zone. The rest of the interval may represent the upper D. davidii Zone.

290.0 – 296.1 m, Diconodinium multispinum Dinoflagellate Zone The lowest occurrence of D. multispinum marks the base of the zone, and the highest occurrence of E. ludbrookiae marks the top. The zone is quite thin, but preservation is exceptionally good and dinocyst yields are high. Ascodinium parvum is common in one sample and D. multispinum, E. ludbrookiae, and L. siphoniphorum are consistently present.

300.1 – 355.0 m, Endoceratium ludbrookiae Dinoflagellate Zone The lowest occurrence of E. ludbrookiae marks the base of the zone, and the lowest occurrence of D. multispinum marks the top. The E. ludbrookiae Zone comprises the major thickness of the Gearle Siltstone in Boologooro 1, and several biostratigraphically significant species have lowest occurrences within this interval. Dioxya armata has a lowest occurrence at 350.1 m, and Craspedodinium indistinctum at 325.1 m.

423–426 m, Muderongia australis Dinoflagellate Zone The presence of M. australis in the absence of M. mcwhaei places this interval in the M. australis Zone. The presence of Muderongia tetracantha and Ovoidinium striatum in this cuttings sample is probably due to caving from higher levels in the well, and the large volume of caved material from the D. davidii Zone and higher zones masks this assemblage. However, there is no evidence for the middle and lower parts of this zone and the assemblage probably represents the upper M. australis Zone.

The dinocyst assemblages are dominated by Chlamydophorella nyei, Diconodinium pusillum, and Spiniferites spp. Diconodinium psilatum becomes common in the middle part of the zone. E. ludbrookiae is relatively infrequent and not recorded in every sample. Spores and pollen range from 6.5 to more than 20% of the total palynomorph assemblage.

460–510 m, optivus–triangulatus Zone

358.1 – 377.8 m, Canninginopsis denticulata Dinoflagellate Zone

This interval is assigned to the Devonian optivus– triangulatus Zone, a spore assemblage zone erected in European and American Devonian successions (Richardson and McGregor, 1986). The three cuttings samples examined from this interval contain caved Cretaceous forms along with clearly Devonian spore assemblages. Similar Devonian assemblages were recorded from the Gneudna Formation in Gneudna 1. The following spores were observed in one or more of these samples: Apiculatisporis adavalensis, Ancyrospora spp., Geminospora lemurata, Emphanisporites rotatus, Calyptosporites stolidotus, ?Medusaspora dringii,

The highest occurrence of Muderongia tetracantha marks the base of the zone, and the lowest occurrence of E. ludbrookiae marks the top. C. denticulata only appears near the top of the zone at about the same depth that Diconodinium spp. become common. Assemblages are dominated numerically by Spiniferites spp., Chlamydophorella spp., Sentusidinium spp., and Cleistosphaeridium spp. In the samples counted from this interval, spores and pollen represent about 29 to 16% of the total palynomorph assemblage. 61

Albian to Lower Campanian calcareous nannofossils by R. W. Howe Geoscience Australia, Canberra

Introduction

Nannofossil observations and comments

Fifteen samples from 182.05 to 304.05 m in the cored interval of Boologooro 1 were examined for calcareous nannofossil biostratigraphy. Nannofossil smear slides were prepared using the techniques outlined in Perch-Nielsen (1985) and Bown and Young (1998). A small amount of fresh rock was scraped onto a coverslip and then smeared evenly with a wet toothpick. The coverslip was then dried on a hotplate before being glued to a glass slide using Norland 61 optical adhesive. The slides were then examined at 1250× magnification using a Zeiss Universal cross-polarizing microscope, and taxa were recorded semiquantitatively.

182.1 m, Subzones UC14b, CC18b This sample has a nannofossil assemblage with high abundance and poor to moderate preservation. Diversity is high, with 60 species present. The sample belongs to Subzones UC14b, CC18b, based on the presence of Aspidolithus parcus constrictus, the lowest occurrence of which marks the bases of Subzones UC14b and CC18b, and the absence of Bukryaster hayi, the lowest occurrence of which marks the base of Subzone UC14c, and the absence of Ceratolithoides verbeeki, the lowest occurrence of which marks the bases of both Subzones UC14d and CC18c.

A total of 155 species were recorded in this study (Tables 3.1 and 3.2). All samples examined contained relatively abundant nannofossils, and were assigned to the Cretaceous UC nannofossil zones of Burnett (1998), and the CC nannofossil zones of Sissingh (1977) and PerchNielsen (1985). Biostratigraphic assignments for the studied interval are summarized in Table 3.3, and discussed below. Many of the marker species in these zonations were not found to be useful, so other biostratigraphically useful species have been used instead.

187.1 – 230.1 m, Subzones UC14a, CC18a This interval has nannofossil assemblages with high abundance and poor to moderate preservation. Diversity is high, with 50 to 58 species present. The interval belongs

The section sampled shows a low level of maturation. The upper Gearle sample contains material that shows properties similar to those of low-rank vitrinite, but with abundant micrinite-like material. Some larger fragments are referable to telovitrinite, but may contain tissues related to suberinite. Some grains of vitrinite that are free of inclusions show reflectances over 0.4% and a figure of about 0.45% may be a better estimate. Some of the vitrinite-like particles may represent small faecal pellets. The Gneudna Formation sample contains a number of grains that are clearly Gearle Siltstone cavings, and these would account for a high percentage of the TOC found. The vitrinite phytoclasts are small and show strong polishing relief. This suggests they are low in rank, but it also means that the mean may understate the level of maturation and a value of about 0.5% is a better estimate. NOTES:

the GSWA regolith program (and in this Record), by first calculating the standard scores for each element so that the concentrations of elements can be compared directly, rather than using the additive index. The CI is calculated for all samples discussed here, and is therefore an index particular to this dataset. The CaO/SiO2 value, gives some indication of the siliciclastic or carbonate content of the sample.

Introduction Analyses of twelve sedimentary rock samples and two pyrite nodules were carried out on the Aptian to Turonian (Cretaceous) section (Windalia Radiolarite, Gearle Siltstone, Haycock Marl, and Toolonga Calcilutite; Table 6.1) from Boologooro 1. The analyses have been used to determine if whole-rock chemistry is a useful tool in lithostratigraphic correlation, and if the Gearle Siltstone in the subsurface is compositionally similar to regolith derived from the same unit in parts of the WINNING POOL* – MINILYA 1:250 000 map sheet, where the unit hosts silver–lead–zinc nodules.

Statistical comparisons of sample populations were made using the Mann-Whitney U test (also known as the Wilcoxon Rank Sum test), which compares population medians based on ranked data. Compared to other tests (e.g. Student’s t-test, which compares population means), it is less sensitive to the effects of outliers, and is therefore more robust (Swan and Sandilands, 1995). Medians have been compared at the 95% level of significance, provided the median value is at least ten times the level of detection for both populations. Values below this level have been excluded, as they may be influenced by low precision near the minimum level of detection.

A total of 27 core samples have been analysed from Edaggee 1, Boologooro 1, and Yinni 1 in the Southern Carnarvon Basin, comprising six from the Windalia Radiolarite, 17 from the Gearle Siltstone (12 from the lower part and five from the upper part), and four from the overlying Haycock Marl. Analyses of pyrite nodules and a barite vein, from the Gearle Siltstone and Windalia Radiolarite respectively, have not been considered in any lithological comparisons. Analyses of the Toolonga Calcilutite (two samples) are also not discussed in statistical comparisons, due to the small population size. Genalysis Laboratory Services Ltd carried out all analyses under conditions discussed in Morris (2000).

Visual inspection of the whole-rock chemistry data, summary logs of each hole, and lithological descriptions provided in Sanders and McGuinness (2001) show that the Cretaceous succession contains locally heterogeneous assemblages, in terms of both host lithologies (e.g. carbonate, carbonaceous, and siliciclastic units), and the development of pyrite and phosphate nodules and barite veining. For the 15 samples from the Gearle Siltstone, the standard deviation is high (occasionally exceeding the mean value) for some analytes, such as Ba (mean = 614 ppm, standard deviation = 675 ppm; n = 15), 8080 and 6925 ppm for S, 293 and 161 ppm for Sr, 7.4 and 7.6% for CaO, and 52.7 and 13.6% for SiO2. In the same unit, pyrite nodules have high values for some analytes. These include 62.1% Fe2O3, 371 ppm As, and 475 800 ppm S in GSWA 176847 from the ‘lower Gearle Siltstone’ in Edaggee 1, and 59.59% Fe2O3 and 382 336 ppm S, but only 6 ppm As in nodule 176854B from the same unit in Boologooro 1. Thus, there is the possibility that there is a greater compositional variation within, rather than between, units. The small population size for some groupings means that some statistical comparisons (e.g. between the Toolonga Calcilutite and Sweeney Mia, and sample populations from Yinni 1) are not possible.

The chemical analyses of 15 stream-sediment samples from the Gearle Siltstone over the Giralia Anticline on WINNING POOL – MINILYA (Sanders and McGuinness, 2001) are compared to those from drillcore. The analytical methodology for these samples is summarized by Sanders and McGuinness (2001) and Morris (2000). Stream sediments provide the closest approximation to bedrock chemistry compared to other regolith types sampled in the GSWA regolith geochemistry program (sandplain, soil, colluvium, lake sediment, sheetwash; Morris and Sanders, 2001). Two indices have been calculated for all samples. The chalcophile index (CI) is the summed standard scores for As, Ag, Bi, Cd, Sb, Mo, Se, and W. Smith et al. (1989) used a similar type of index to identify chalcophile element corridors in Archaean greenstones of the Yilgarn Craton. Their approach has been adopted and modified for

The eight samples of the Gearle Siltstone from Boologooro 1 were statistically compared to four samples from Edaggee 1 to determine the degree of lithological homogeneity within the Gearle Siltstone between the two wells, which are about 100 km apart. Median values for the Gearle Siltstone in the two wells are shown in Table 6.2. There are insufficient samples from Yinni 1 (3) to include it in this comparison. The Mann-Whitney U test shows that there is a greater than 95% possibility that medians are different between the two populations for seven analytes. The median value for Ba of 1697 ppm in Edaggee 1 is an order of magnitude higher than in Boologooro 1 (183 ppm), and median values for P 2O5 and Y are also higher in Edaggee 1. Median values for Fe2O3, V, and Be are lower in Edaggee 1 than in Boologooro 1. One interpretation is that differences in Ba, P2O5 and Y reflect localized development of barite and phosphate nodules, whereas differences in Fe2O3 and V could reflect different degrees of ferruginization. Following from this, nodule and vein development, and ferruginization could be secondary processes superimposed on a relatively homogenous parent lithology.

Comparison of the lower and upper parts of the Gearle Siltstone Median values for the lower (11 samples) and upper (four samples) parts of the Gearle Siltstone from the three wells (Table 6.3) show that the lower part of the unit has statistically higher median values for SiO2, MgO, and Na2O, and lower median values for CaO, LOI, Co, Li, Sr, and CaO/SiO2. In the upper part of the unit, the association of higher CaO (and CaO/SiO2), LOI, and Sr, along with lower SiO2, MgO, and Na2O indicates a higher carbonate content (lower siliciclastic component). Because the overlying Haycock Marl is more carbonate rich than the uppermost Gearle Siltstone, this is taken to reflect a gradual increase in carbonate content throughout the section. Only eight median values are statistically different between the lower and upper parts of the Gearle Siltstone, indicating that the unit is largely homogeneous, which is consistent with the comparison of the Gearle Siltstone between Boologooro 1 and Edaggee 1.

Comparison of the Gearle Siltstone and Haycock Marl

This comparison is made with only four samples from the Haycock Marl, compared to 15 from the Gearle Siltstone. The wide range in concentration of some analytes (e.g. CaO within Haycock Marl; Fig. 6.1) means that there is no statistical difference between some median values.

Comparison of median values (Table 6.3) shows that the Gearle Siltstone has higher median values for SiO2, MgO, Na2O, Ba, Ce, Rb, and Th, and statistically lower median values for P2O5, LOI, Co, Ni, Pd, Se, CaO/SiO2, and CI. Overall, this shows the more carbonate-rich nature of the Haycock Marl, although its wide range in carbonate content (Fig. 6.1) means that this is only evident in terms of comparing CaO/SiO2 rather than CaO. Similarly, the higher siliciclastic (lower carbonate) content of the Gearle Siltstone is shown by its higher median values for components such as MgO, Na 2O, Ba, and Rb. The statistically higher Co, Ni, Pd, and CI median values for the Haycock Marl indicate a greater potential for mineralization.

Zn, and CI (Table 6.3). There is no statistical difference between median values for CaO, LOI, Sn, Sr, U, V, Zr, and CaO/SiO 2. Overall, the core samples show considerable differences in composition to the stream sediments. Sanders and McGuinness (2001) noted the presence of carbonate-rich duricrust and surface silicification in the Giralia Anticline region; the latter may explain the higher median SiO 2 value in the stream sediments. Local development of barite in the Giralia Anticline region, also discussed by Sanders and McGuinness (2001), is reflected in regolith samples by the wide variation in Ba content. It is therefore likely that the fundamental differences in chemistry between the Gearle Siltstone in the subsurface and derived stream sediment reflect a combination of lithological variability, coupled with localized development of barite, and subsequent mechanical and chemical weathering.

Regolith from the Gearle Siltstone over the Giralia Anticline had exceptionally high concentrations of Ba (average 3543 ppm), along with high values for Fe2O3, CaO, LOI, As, Mo, Ni, Se, U, and Zn, with some samples also having high P 2O5, Co, Cu, In, Pd, S, Sn, and V (Sanders and McGuinness, 2001). High Ba in regolith is presumably associated with barite mineralization in the Cardabia Creek area of the Giralia Anticline, where there are beds of barite crystals up to 30 cm thick in shales and siltstones. The western flank of this anticline contains nodules of barite up to 30 cm in diameter over an area extending to about 25 km from Cardabia Creek. Statistics for the 15 stream sediments from the Giralia Anticline region on WINNING POOL – MINILYA (Sanders and McGuinness, 2001) show wide variations in the concentrations of elements such as CaO (mean 8.41%, standard deviation 11.34%), Na 2O (0.25, 0.52%), Ba (3840, 5878 ppm), Cr (44, 27 ppm), S (3200, 5967 ppm), Sr (376, 334 ppm), Zn (48, 23 ppm), and Zr (115, 62 ppm). Thus, any comparison of median values will be affected by the wide ranges in the concentrations of some analytes.

Discussion Statistical comparisons of the Gearle Siltstone between drillholes, and between lower and upper parts of the same unit show limited chemical heterogeneity despite the development of pyrite and phosphate nodules and barite veins, and some heterogeneity in terms of lithology (e.g. carbonaceous and carbonate-rich, as well as siliciclastic, rock types). This is surprising, considering the extreme values for analytes such as S, As, Fe, and Ba in veins or nodules. One statistical test has shown an increase in carbonate content with stratigraphic height, which is consistent with the higher carbonate content of the overlying Haycock Marl. Compared to units above and

A statistical comparison shows that stream sediments have higher median values for SiO2, As, Ba, and Mo, and lower median values for TiO2, Al2O3, MgO, Na2O, K2O, Ce, Co, Cr, Cu, Ga, La, Li, Nb, Ni, Pb, Rb, S, Sc, Th, Y, 103

below, the Gearle Siltstone has higher median values for MgO, Rb, and Th, and lower median values for P2O5 and CI.

The large number of median values, which are statistically different between the Windalia Radiolarite and Gearle Siltstone, indicate that the two formations have fundamentally different compositions, as could be expected.

A., 2001, Geochemical mapping of the Winning Pool – Minilya 1:250 000 sheets: Western Australia Geological Survey, 1:250 000 Regolith Geochemistry Series Explanatory Notes, 57p. SMITH, R.

F., 1989, The implications to exploration of chalcophile corridors in the Archaean Yilgarn Block, Western Australia, as revealed by laterite geochemistry: Journal of Geochemical Exploration, v. 32, p. 169–184.

In drillcore the Gearle Siltstone shows little in common with stream sediments derived from the unit on WINNING POOL – MINILYA, whereas there is little variation in the unit between Edaggee 1 and Boologooro 1. A more likely explanation is that the stream sediments represent the combined effects of barite veining and low-temperature alteration, in addition to surface silicification and subsequent mechanical sorting and chemical weathering during the regolith forming process.
