Queensland Gravity Data (P200142), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected 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.
 This Queensland Gravity Data (P200142) contains a total of 33 point data values acquired at a spacing of 750 metres. The data is located in QLD and were acquired in 2001, under project No. 200142 for None.

New discoveries of Devonian vertebrates from the Amadeus Basin, central Australia

Devonian vertebrate occurrences are reviewed from nine localities in the Amadeus Basin, of which five are new. Acanthodian, phyllolepid placoderm, rhipidistian, and dipnoan fishes are recorded from near Stokes Pass, for the first time from the Parke Siltstone of the Pertnjara Group. Several different species of the antiarch Bothriolepis are provisionally identified in the same faunas. An older fauna, which contains phlyctaeniid euarthrodires, other placoderms, and acanthodians, but not Bothriolepis, is definitely known only from an occurrence at Gosses Bluff. The stratigraphic position of this assemblage is uncertain. Comparisons of sediment thickness between broadly equivalent fossil horizons in the Dulcie Sandstone (Georgina Basin) suggest that if the Gosses Bluff fauna occurs in basal beds of the Mereenie Sandstone, then this probably does not correspond to the base of the formation in other sections where it attains a much greater thickness. It is suggested that the Gosses Bluff fauna may correlate with the Wuttagoonaspis assemblage from the Merrimerriwa Formation of the Mulga Downs Group in western New South Wales and the Cravens Peak Beds and lower Dulcie Sandstone in the Georgina Basin . The age of this assemblage is probably late Early Devonian. Evidence provided by palynology and vertebrate palaeontology for the age of the Parke Siltstone is reviewed, and a Givetian-Frasnian age is suggested. The placoderm Phyllolepis is a typical Late Devonian form, but its downward range in Australian sequences is not yet established. Acanthodian and dipnoan evidence points to a Middle Devonian age. Regarding the age of the underlying Mereenie Sandstone, it seems unlikely that the whole formation is Devonian. The Rodingan Movement was more likely a Silurian event. It is possible that the age of magnetisation measured from the lower part of the Mereenie Sandstone at Ellery Creek is Early Devonian or older, and thus consistent with a subplate model for the Palaeozoic apparent polar wander curve for Australia.  The presence of Phyllolepis and Wuttagoonaspis in the central Australian Devonian fish faunas indicates affinities with southeastern Australia, where these taxa are known from many localities.

Yathong Magnetic Gradient and Radiometric Survey, NSW, 2023, (P5023), K equivalent ground concentration grid

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected 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.
This radiometric potassium grid has a cell size of  degrees (approximately 40m) and shows potassium element concentration of the Yathong airborne magnetic gradient and radiometric survey, 2023 in units of percent (or %). The data used to produce this grid was acquired in 2023 by the NSW Government, and consisted of 65504 line-kilometres of data at 200m line spacing and 80m terrain clearance.

Radiometric Map of Australia presentation

Geoscience Australia and State and Territory Geological Surveys have systematically surveyed most of the Australian continent over the past 40 years using airborne gamma-ray spectrometry to map potassium, uranium and thorium elemental concentrations at the Earth's surface. However, the individual surveys that comprise the national gamma-ray spectrometric radioelement database are not all registered to the same datum. This limits the usefulness of the database as it is not possible to easily combine surveys into regional compilations or make accurate comparisons between radiometric signatures in different survey areas. To solve these problems, Geoscience Australia has undertaken an Australia-Wide Airborne Geophysical Survey (AWAGS), funded under the Australian Government's Onshore Energy Security Program, to serve as a radioelement baseline for all current and future airborne gamma-ray spectrometric surveys in Australia. The AWAGS survey has been back-calibrated to the International Atomic Energy Agency's (IAEA) radioelement datum. We have used the AWAGS data to level the national radioelement database by estimating survey correction factors that, once applied, minimize both the differences in radioelement estimates between surveys (where these surveys overlap) and the differences between the surveys and the AWAGS traverses. The database is thus effectively levelled to the IAEA datum. The levelled database has been used to produce the first 'Radiometric Map of Australia' - levelled and merged composite potassium (% K), uranium (ppm eU) and thorium (ppm eTh) grids over Australia at 100 m resolution. Interpreters can use the map to reliably compare the radiometric signatures observed over different parts of Australia. This enables the assessment of key mineralogical and geochemical properties of bedrock and regolith materials from different geological provinces and regions with contrasting landscape histories.

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.

Geology of the Donors Hill

These data are a digital representation of information depicted on the printed map of the Donors Hill 1:250 000 Geological Series produced by AGSO and the Geological Survey of Queensland (GSQ) in 1972 (1st edition).
Data present include geological polygons (litho-stratigraphic units), linear structural features (faults, dykes, folds, trends, lineaments etc), and point features (mines, structural points etc). Polygons have a range of attributes extracted from each individual map including unit name, age and lithological description, while lines and points are feature coded according to the AGSO publication 'Symbols Used On Geological Maps' (BMR 1989). A standard look-up table of AGSO geological codes and associated descriptions is available (see ADDITIONAL METADATA).
The data has gradually evolved from elementary CAD quality data into its present topologically structured GIS format, and hence has many imperfections and inconsistencies. Data has undergone rigorous validation and testing that includes over 80 different tests. See ADDITIONAL METADATA for more information on the data standards used.

Magnesite-bearing calcrete near Gosses Bluff, Northern Territory

Small nodules and tabular bodies of practically pure micro-crystalline magnesite up to a few centimetres across occur in late Cainozoic calcrete around Gosses Bluff. The calcrete underlies an area of about 15 km^2 and the magnesite constitutes somewhat less than 1 per cent of the outcrop. The bedrock in the area of calcrete is impact breccia of the Gosses Bluff structure. The superficial weathered products of these breccias constituted a suitable host rock for the calcrete because of their inherent permeability and their position in topographically low areas. The source of magnesium carbonate was most likely in the Late Proterozoic and Palaeozoic dolomites and magnesian limestones exposed to the north in the MacDonnell Ranges. Petrographic evidence from the random samples of calcrete collected at Gosses Bluff suggests that the history of the deposit commenced with invasion of magnesium carbonate rich waters and formation of small bodies, probably of a metastable hydrate of magnesite which later reverted to the stable phase. A period of sub-aerial dessication ensued and caused disintegration of the nodules and production of cracks and voids. Phreatic water enriched in calcium carbonate invaded the deposit; voids were lined with fibrous calcite, smaller cracks were completely filled, and at the same time the magnesite was replaced, in part, by calcite. The larger voids were subsequently filled by calcrete which consisted of a mixture of disintegrated breccia fragments, chiefly quartz, feldspar and quartzite grains, with the addition of a minor proportion of magnesite grains incorporated from the nodules; and an abundant matrix of calcite. There is scant reference to magnesite in calcretes elsewhere in Australia, possibly because magnesite is not readily distinguished in some fine-grained calcretes.
