Gairdner - K equivalent concentration grid (AWAGS, no nasvd)

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. 
The Geological Survey of South Australia commissioned the Gawler Craton Airborne Survey (GCAS) as part of the PACE Copper initiative. The airborne geophysical survey was flown over parts of the Gawler Craton in South Australia. The program was designed to capture new baseline geoscientific data to provide further information on the geological context and setting of the area for mineral systems. 
This radiometric potassium grid has a cell size of 0.0004 degrees (approximately 41m) and shows potassium element concentration of the Gairdner Airborne Magnetic Radiometric and DEM survey, SA, 2018 in units of percent (or %). The data used to produce this grid was acquired in 2018 by the SA Government, and consisted of 104788 line-kilometres of data at 200m line spacing and 60m terrain clearance. To constrain long wavelengths in the grid, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey grid.

Bowen Surat Gravity Complete Bouguer Anomaly 1VD

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 Bowen Surat Gravity Complete Bouguer Anomaly 1VD is a complete Bouguer anomaly grid for the Bowen Surat (P200540). A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid.  This gravity survey was acquired under the project No. 200540 for the geological survey of QLD. The grid has a cell size of 0.00764 degrees (approximately 800m). A total of 4977 gravity stations were acquired to produce this grid.

Further Petalichthyid remains (Placoderm fishes, Early Devonian) from the Taemas-Wee Jasper region, New South Wales

New material referable to the order Petalichthyida (placodermi) is described from the Early Devonian limestones of the Taemas-Wee Jasper area, New South Wales. Shearsbyaspis oepiki gen. et sp. nov. is represented by two incomplete skulls, one including parts of the endocranium. It differs from other genera in having discrete rostral and pineal plates that completely separate the preorbitals of each side. It resembles Lunaspis in the size of the central plates, and Wijdeaspis in the shape of the anterior paranuchal plate. In the endocranium, a lateral preorbital space is identified, communicating posteriorly with the orbital cavity. In the orbit, the optic nerve foramen and eyestalk attachment area are described. Two foramina behind the optic nerve foramen, possibly for anterior and posterior branches of the oculomotor nerve, are not associated with a myodome. Isolated median dorsal, spinal, and ventral trunk-shield plates are assigned to Lunaspis sp.on the basis of ornament. The median dorsal plate carries a median ventral cavity near its posterior margin, a structure not previously described in petalichthyids. Three competing hypotheses of petalichthyid relationships are briefly discussed. It is suggested that the ventral cavity on the median dorsal is primitive for placoderms, and the position of the corresponding cavity in antiarchs, anterior to the transverse thickening, might be a derived condition.

Einasleigh 1:250 000 topographic map

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD.

Exploring for the Future – Interpreted horizons of the Barkly Seismic Survey.

The first phase of the Australian Government's Exploring for the Future (EFTF) was a multi-year (2016-2020) $100.5 million initiative to increase northern Australia's desirability as a destination for industry investment to stimulate ‘greenfield’ resource exploration. In order to support this fundamental objective of the EFTF program, Geoscience Australia conducted acquisition of a diverse range of new precompetitive datasets across northern Australia, focussing on regions of unrecognised mineral, energy and groundwater resource potential.
The Barkly 2D Deep Crustal Reflection Seismic Survey (L212) was acquired in 2019 as a major objective of the EFTF program in partnership with, and co-funded by, the NT Government under the Resourcing the Territory initiative. The Barkly Seismic Survey extends from the newly discovered Carrara Sub-basin in the South Nicholson Basin region to the south-eastern margins of the Beetaloo Sub-basin (Fomin, T., et al. 2019). The Barkly Seismic Survey images interpreted Paleoproterozoic to Mesoproterozoic successions extending from the Carrara Sub-basin to the highly prospective Beetaloo Sub-basin of the McArthur Basin. These successions are concealed by a persistent cover of up to 600 m of Paleozoic Georgina Basin sediments. Interpretation of the Barkly Seismic Survey established three informal geological domains, each defined by structural elements and/or basin characteristics (Southby et al, 2021).
This data set contains an exported set of XYZ points from interpreted horizons (Southby et al 2022,) on the Barkly Seismic Survey (L212)  in both two way time (TWT ms on PreSTM_19ga lines) and depth (m) re-interpreted on depth indexed PreSDM_19GA lines. The coordinate reference system for this dataset is WGS 1984 Australian Centre for Remote Sensing Lambert. Seismic reference datum is 350 m. The seismic reference datum are described in the EBCDIC headers of the SEGY files for each of the survey lines.
