Cambridge Gulf total count grid geodetic

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 terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This Cambridge Gulf total count grid geodetic has a cell size of 0.00083 degrees (approximately 91m) and shows the terrestrial dose rate of the Cambridge Gulf, WA, 1994. The data used to produce this grid was acquired in 1994 by the WA Government, and consisted of 51219 line-kilometres of data at 400m line spacing and 60m terrain clearance.

Tallaringa North - 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 North - TMI RTP 1VD grid (AWAGS) is the first vertical derivative of the TMI RTP grid of the Tallaringa North Airborne Magnetic Radiometric and DEM Survey, SA, 2017 survey.
This grid has a cell size of 0.00042 degrees (approximately 44m) , 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 98230 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 North 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.

Seabed environments and shallow geology of the Vlaming sub-basin, Western Australia: Grain size and carbonate concentrations of seabed sediment.

Geoscience Australia undertook a marine survey of the Vlaming Sub-basin in March and April 2012 to provide seabed and shallow geological information to support an assessment of the CO2 storage potential of this sedimentary basin. The survey was undertaken under the Australian Government's National CO2 Infrastructure Plan (NCIP) to help identify sites suitable for the long term storage of CO2 within reasonable distances of major sources of CO2 emissions. The Vlaming Sub-basin is located offshore from Perth, Western Australia, and was previously identified by the Carbon Storage Taskforce (2009) as potentially highly suitable for CO2 storage. The principal aim of the Vlaming Sub-basin marine survey (GA survey number GA334) was to look for evidence of any past or current gas or fluid seepage at the seabed, and to determine whether these features are related to structures (e.g. faults) in the Vlaming Sub-basin that may extend up to the seabed. The survey also mapped seabed habitats and biota in the areas of interest to provide information on communities and biophysical features that may be associated with seepage. This research addresses key questions on the potential for containment of CO2 in the Early Cretaceous Gage Sandstone (the basin's proposed CO2 storage unit) and the regional integrity of the South Perth Shale (the seal unit that overlies the Gage Sandstone). This dataset comprises grain size data and carbonate concentrations of the upper ~2cm of seabed sediment.

Exploring for the Future in the Officer Musgrave region

To unlock the potential of one of the largest underexplored onshore areas in Australia, the Exploring for the Future Officer-Musgrave project is delivering a wide array of publicly available new analyses and data. The collection of new AEM data, as well as the reprocessing of existing industry acquired AEM data is expected to improve the understanding of groundwater systems in the Officer-Musgrave region. New regional scale data acquisition and analysis, including stratigraphic, petrophysical and geomechanical studies from existing wells, focus on advancing understanding of petroleum systems elements and assist the exploration and evaluation of conventional and unconventional petroleum resources. Here we provide an overview of available new datasets and insights into the stratigraphy of the Officer Basin. Further analysis is underway including well log digitisation, fluid inclusion analysis and a petrographic report on Officer Basin wells. This work is expected to further improve geological knowledge and reduce the energy exploration risk of the Officer Basin, a key focus of this program.

Regional constrained 3D inversion of potential field data from the Olympic Cu-Au province, South Australia

The almost complete absence of basement outcrop or surface expression of mineralisation is the prime impediment to mineral exploration in the Gawler Craton of South Australia, and large areas elsewhere in Australia (Fig. 1). To explore in these covered terranes, we need high quality regional information, plus tools and techniques that allow us to better utilise the limited direct geological information from buried rocks. Analysis of potential-field data is one of the most common and cost-effective ways of inferring hidden geology. There are high quality aeromagnetic data available over most of the actively explored areas of Australia, and it is hoped that more closely-spaced ground gravity measurements, together with improvements in airborne gravity and airborne gravity gradiometer methods, will in the future raise the standard of gravity coverage to that of the magnetics.

Geoscience Australia conducted a marine seismic survey (GA-0349) over poorly defined areas of the Houtman sub-basin (part of the Perth basin) between 15th of November to the 23rd of January 2015. The aim was to acquire high quality, industry-standard precompetitive 2D seismic data, Multi-beam echo-sounder (MBES) off the coast of Western Australia. The new seismic data will supplement existing geological knowledge of the region, underpin petroleum prospectivity evaluation and support the discovery of new oil gas resources.This dataset is not to be used for navigational purposes.
