Gippsland Basin Biozonation and Stratigraphy Chart No. 18

Biostratigraphy is the branch of stratigraphy that uses fossils to establish relative ages of rock and correlate successions of sedimentary rocks within and between depositional basins. A biozone is an interval of geologic strata characterised by certain fossil taxa. Such intervals are often defined by the first appearances (range bases), apparent extinctions (range tops/last appearances), or abundances of fossil index species. These key index species should be relatively abundant, short-lived taxa that are easy to recognise and as geographically widespread as possible. Widely used fossil groups include brachiopods, conodonts, dinoflagellate cysts, foraminifera, graptolites, nannofossil, spores and pollen and trilobites. Zonal schemes based on several different fossil groups can be used in parallel, and the zones can be calibrated to the absolute geological timescale using tie points to rocks which have been radio-isotopically dated.

Squid3: Next-generation data processing software for Sensitive High Resolution Ion Micro Probe (SHRIMP)

The Isotopic Atlas of Australia is one of the fundamental datasets in Geoscience Australia (GA)’s Exploring for the Future program. It is underpinned by a nationwide coverage of high-quality U-Th-Pb radiometric dates, mostly determined by Sensitive High Resolution Ion Micro Probe (SHRIMP). For the past decade, GA and the international SHRIMP community have relied on SQUID 2.50 software to process isotopic data acquired by SHRIMP for U-Th-Pb geochronology. However, SQUID 2.50 is obsolete because of dependency on Excel 2003, which is unsupported by Microsoft and will not operate on Windows 10. As a result, GA collaborated with the Cyber Infrastructure Research and Development Laboratory for Earth Sciences (CIRDLES.org) at the College of Charleston (USA) to redeploy SQUID 2.50 algorithms in an open-source, platform-independent and freely available Java application (Squid3). Squid3 replicates (rather than seeking to enhance) SQUID 2.50 logic and arithmetic, with substantial improvements in flexibility and interactivity. In this paper, we review documentation detailing widely trusted but little-known SQUID 2.50 algorithms and provide an overview of Squid3, focusing on the implementation and improvement of SQUID 2.50 functionality. The beta version of Squid3 is capable of end-to-end U-Th-Pb data processing, from ingestion of raw SHRIMP .xml files, through finalised summary calculations, to reporting of data arrays suitable for visualisation via packages such as Isoplot, Topsoil and IsoplotR. In production, Squid3 will enable users to sever links with Excel 2003, while ensuring the sustainability, reliability and relevance of SHRIMP data.

AUSGeoid98 v.1.0 data files:  (sg48-12)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

U-K-A. Wandoan No. 1, Queensland Of Union Oil Development Corporation Kern County Land Company And Australian Oil And Gas Corporation Limited

Union - Kern - A.O.G. Wandoan No. 1 was the first wildcat drilled by Union Oil Development Corporation in the north-eastern part of the Surat Basin. Union - Kern A. O.G. Moonie No. 1 had proven the potential of the Jurassic-Triassic Precipice Sandstone as an oil reservoir and it was necessary to evaluate this reservoir in other parts of the basin. In the Wandoan area seismic surveys defined a large north-plunging anticline in rocks of the Bowen Group, with a domal closure in the Great Artesian Group superimposed on the north plunge of the feature. This domal closure shows more than 200 feet of vertical closure encompassing an area of 30 square miles. The Wandoan well was programmed primarily to test the petroleum potential of the Precipice Sandstone on this closure.
Drilling commenced on 22nd April, 1962 and the well was completed on 18th June, 1962 as a dry hole at a total depth of 10,736 feet. A full programme of logging, testing, and coring was undertaken.
Wandoan No. 1 Well established the presence of4798 feet of Mesozoic sediments of the Great Artesian Group resting disconformably on 5919 feet of Lower Mesozoic-Upper Palaeozoic strata of the Bowen Group. Testing over the interval 3260 to 3278 feet indicated that the Precipice Sandstone has excellent reservoir characteristics. Yellowish to bluishwhite fluorescence in the samples, and traces of hydrocarbons in the formation water from this interval indicated that hydrocarbons have migrated through the sandstone. Fluorescence and minor gas shows in the upper part of the Bowen Group were noted but the reservoir characteristics of these rocks were unfavourable for an accumulation of oil and gas.
The well bottomed at 10,736 feet in coals and tuffs of the Kianga Formation. Cement plugs were set and the well was abandoned on 21st June, 1962.

SA Exploration Initiative - Area B4, SA, 1993 (P701), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the SA Exploration Initiative - Area B, (B1- B4) SA, 1993 survey were acquired in 1993 by the SA Government, and consisted of 75571 line-kilometres of data at 400m line spacing and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

New Palaeogeographic Maps of the northern margins of the Australian plate - Updated report

A variety of alternative reconstructions are considered for the northern margins of the Australian plate. The simplest solution involves Hall's (2002) configuration for the microplates  in the Greater Birds Head. Prior to the early Permian, the Greater Birds Head is thought to have lain adjacent to northern Australia from Timor to the Kai islands. After Meso-Tethys breakup in the Sakmarian, it then rotated away during the Permian to Middle Triassic to form the proto-Banda Sea and the spreading centre was then abandoned. From the Middle Triassic to the Oligocene, the Greater Birds Head was probably a relatively stable promontory of northern Australia and was then fragmented, tectonised and incorporated into the SE Asian island arc system during the late Oligocene to Holocene.
The palaeogeographic maps are updated to incorporate these new plate models. The tectonostratigraphic evolution of northern Australia is divided into several phases. During the Carboniferous to Sakmarian pre-breakup phase, the Westralian Superbasin was characterised by rifting, deltas and various types of glacial sedimentation. After the Sakmarian Meso-Tethys breakup, there were large amounts of deltaic clastic sedimentation, lasting until Argoland drifted away in the Late Jurassic. The New England Orogeny overlapped with the first part of this phase on the NE margin until the Middle Triassic. There was a long period of post-breakup marine rift basin formation in NW Australia from the Oxfordian to the Valanginian. Indian Ocean breakup then led to rapid thermal subsidence. The rest of the Cretaceous was characterised by passive tectonics with largely fine-grained sedimentation on the NW margin, and increasing volcanicity and rifting on the NE side of the continent. Shifting areas of rifting and breakup, largely in a backarc setting affected the NE margins in the latest Cretaceous to early Eocene. Carbonate progradation started in the Westralian Superbasin in the Paleocene. The Eocene to Holocene history has been marked by passive carbonate progradation on the NW margin and multiple collisions in the N and NE.
Many of the tectonic models put forward in this study are very difficult to substantiate using the data currently available and alternative scenarios are a strong possibility. The way forward is now to formulate research programmes that would help to narrow down these alternatives and better document the history of this very complex margin.
