P201750 Coompana Gravity Survey CSCBA267GU

Gravity data measure 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 P201750 Coompana Gravity Survey CSCBA267GU is a complete spherical cap Bouguer anomaly grid for the Coompana Gravity Survey (P201750). This gravity survey was acquired under the project No. 201750 for the geological survey of SA. The grid has a cell size of 0.00387 degrees (approximately 398m).

Seafloor environments of the northern Lord Howe Rise, Eastern Australia: Mineralogy of seabed sediments.

Geoscience Australia marine reconnaissance survey TAN0713 to the Lord Howe Rise offshore eastern Australia was completed as part of the Federal Government's Offshore Energy Security Program between 7 October and 22 November 2007 using the New Zealand Government's research vessel Tangaroa. The survey was designed to sample key, deep-sea environments on the east Australian margin (a relatively poorly-studied shelf region in terms of sedimentology and benthic habitats) to better define the Capel and Faust basins, which are two major sedimentary basins beneath the Lord Howe Rise. Samples recovered on the survey contribute to a better understanding of the geology of the basins and assist with an appraisal of their petroleum potential. They also add to the inventory of baseline data on deep-sea sediments in Australia. The principal scientific objectives of the survey were to: (1) characterise the physical properties of the seabed associated with the Capel and Faust basins and Gifford Guyot; (2) investigate the geological history of the Capel and Faust basins from a geophysical and geological perspective; and (3) characterise the abiotic and biotic relationships on an offshore submerged plateau, a seamount, and locations where fluid escape features were evident. This dataset comprises mineraology data (e.g. concentrations of bulk carbonate, calcite, aragonite, halite, quartz) from seanbed sediments (0-2cm).
Some relevant publications which pertain to these datasets include:

National Base Land Parcels (May 2025)

National Base Land Parcels (Land Parcels) are a spatial representation of land parcels defined and maintained by the state and territory governments of Australia. It combines the complex representations unique to each jurisdiction into a consistent, seamless view of Australia's land parcels.&nbsp;

Australian land parcels represent the smallest legal area of land that can be sold without needing approval to subdivide. These parcels can be referenced by a land title through the relevant state or territory land registry, which offers links to jurisdictional information such as:
- certificate of title or Crown lease&nbsp;&nbsp;
- valuation information&nbsp;
- land descriptions.&nbsp;

The National Base Land Parcels dataset is available to Commonwealth Government users of the Digital Atlas of Australia. Contact DigitalAtlas@ga.gov.au for access.&nbsp;

Tallaringa South - TMI RTP 1VD grid (AWAGS)

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. .
 This Tallaringa South - TMI RTP 1VD grid (AWAGS) is the first vertical derivative of the TMI RTP grid of the Tallaringa South Airborne Magnetic Radiometric and DEM Survey, SA, 2017 survey.
This grid has a cell size of 0.0004 degrees (approximately 42m) , and given in units of nT per metre (nT/m).  The data used to produce the TMI grid was acquired in 2017 by the SA Government, and consisted of 146285 line-kilometres of data at 200m line spacing and 60m terrain clearance. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey. A first vertical derivative was calculated by applying a fast Fourier transform (FFT) process to the TMI RTP grid of the Tallaringa South Airborne Magnetic Radiometric and DEM Survey, SA, 2017 survey to produce this grid. This grid was calculated using an algorithm from the INTREPID Geophysics software package. This grid shows the magnetic response of subsurface features with contrasting magnetic susceptibilities. The grid can also be used to locate structural features such as dykes.

Geophysical surveys, Oaklands-Coorabin Coalfield, New South Wales

The Oaklands-Coorabin Coalfield in the Riverina Division of New South Wales has been known for many years. Coal is produced from a small colliery near Coorabin and a minor amount of exploratory drilling in the general vicinity of this mine has been carried out by New South Wales and Commonwealth Government authorities. This exploration has shown that coal seams extend over an area of a few square miles near Coorabin. The coal occurs in Permian rocks which do not crop out but are covered by Tertiary and younger sediments with a minimum thickness of 100 feet. Examination of the regional geology led to the conclusion that the coalfield is far more extensive than the limited area proved by drilling. Because of the Tertiary cover, normal geological methods cannot be used to map the boundaries of the Coal Measures and for this reason geophysical survey's, which have been used successfully on similar problems elsewhere, were undertaken to map the sedimentary basin. A gravity survey was carried out first and as the work proceeded it became obvious that a pronounced regional anomaly is present. Consequently, seismic methods were employed to try to obtain the thickness of the sediments at a number of critical places and to provide a control for separating the effect of the sediments from the regional effect. A residual gravity contour plan was obtained and indicates the general shape of the sedimentary basin.  This plan provides a satisfactory basis for recommending drilling to test the potentialities of the basin. An area of approximately 1,450 square miles was covered by the geophysical surveys and, after correcting for regional effect, the residual gravity pattern suggests the presence of a Permian basin approximately 600 square miles in area, with a possible extension in a north-westerly direction. Recommendations are made for testing the geophysical results by drilling at five widely-spaced sites in the supposed basin. Five additional drilling sites are recommended and are designed to prove reserves near the known coal occurrences.
