The Tasmanian TASGO 3D model is a model of the geological structure of Tasmania. It contains: interpretations of the TASGO seismic reflection data and reflection and refraction paths from the TASGO seismic refraction survey, plus elevation, bathymetry, satellite imagery, geology maps, geophysical images, major geological structures, gold deposits, geochronology sites, and Dundas area seismic interpretations, cross-sections and fault planes. It is an interactive VRML (Virtual Reality Modelling Language) model. Users can turn data layers on and off and manipulate the model by rotating, zooming and panning. It is a product of the TASGO project, a National Geoscience Agreement (NGA) project between Mineral Resources Tasmania and Geoscience Australia.

These data comprises the 3D geophysical and geological map of the Georgina-Arunta region, Northern Territory. This 3D map summarises the key basement provinces of this region, including the geometric relationships between these provinces. Depth of cover data, and approximate thicknesses of key basins within the region are also provided. Supporting geophysical studies, including inversions of gravity and magnetic data, and seismic data and their corresponding interpretations acquired under the Australian Government's Onshore Energy Security Program, are included with this 3D map. Finally, additional data, such as topographic data, are also included.

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 Geoscience Australia'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 100m 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. The Radiometric Map of Australia is available as a free PDF or JPG (2nd edition). The gridded digital data which underpins the Radiometric Map of Australia is available free of charge for download using the Geophysical Archive Data Delivery System (GADDS). Because the grids are large (approximately 5.5 GB each), users planning to access entire grids at full resolution should contact <a href=\mailto:minerals@ga.gov.au\">minerals@ga.gov.au</a> to arrange alternative means of acquiring the digital data."

Geoscience Australia (GA) has created a unique collection of 3D structural and geological models and model inputs for Australia and its near shore regions. Currently the collection contains a variety of 3D volumetric models and surfaces that were produced for specific projects at regional to continental scale. The approximately 40 regional scale models in the collection cover roughly 1/3 of the Australian continent. The models capture 3D stratigraphy and architecture, including the depth to bedrock and the locations of different major rock units, faults and geological structures. The geologic models represent the integration of geophysical surveys, seismic surveys, borehole data, field geology, and geochemical data, the majority of which will now be available through this and other RDSI collections. In their current form, the 3D models provide a valuable input to simulations of geological processes. However, the plan over time is to use the HPC capability at NCI and the large storage volumes available to dynamically integrate the various models and geological, geochemical and geophysical derivative products to then create a unified 3D model for the entire continent. Separately and then cumulatively, these models will provide an important new basis for describing and understanding Australia's geologic evolution and resource wealth. Currently there are no international open standards for the development and storage of 3D geological models, which is why they are difficult to integrate or stitch into nationally integrated data sets. The lack of consistency of the models means that each has to be transformed into formats compatible with existing HP modelling and simulation software. It is hoped that through exposing these 3D geological models into a HP collaborative environment that this will foster and accelerate the development of international standards and tools necessary for the assimilation of 3D geological models into a variety of HP programs. <b> Note: This record has been superseded by eCat 144629:</b> - <a href="https://pid.geoscience.gov.au/dataset/ga/144629">https://pid.geoscience.gov.au/dataset/ga/144629</a>

The Common Earth Model is a collection of data collated by Geoscience Australia that aims to give a unified overview of the geology of Australia. The data are visualised in the Geoscience Australia 3D Data Viewer software and the intention is to give users a rich environment to explore diverse geological data. Geoscience Australia has collated these datasets from a wide range of sources.
