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. Software required Geoscience Australia's X3D and older VRML models require the free plugin BS Contact and work best with the web browser Internet Explorer version 6 or higher.

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."

<b>Note: 3D VRML model is no longer supported</b> This 4th version of the Tanami 3D model covers a 200 km x 200 km area of the Tanami Region and Arunta Inlier (Aileron Province). This model consists of a series of 3D surfaces of major geological elements ranging from relatively shallow cover sequences, down to the Moho. The 3D surfaces were constructed using 3D GeoModeller and combines the interpreted seismic data from the 2005 Tanami Seismic Collaborative Research Project, with geological mapping, interpreted solid geology maps, and gravity and magnetic data. Elements of the model have been tested by gravity forward modelling. Geographic extent Tanami Region, Northern Territory-Western Australia. Contents Digital elevation model; images of magnetics, gravity, radiometrics, satellite imagery, mapped geology and regolith; roads; images of solid geology interpretation maps; modelled cross-sections; 3D fault surfaces; gravity and magnetic inversion surfaces; gravity and magnetics strings; mineral occurrences; SHRIMP geochronology; seismic images; and depth to basement points, surfaces and contours.

<b>Note: 3D VRML model is no longer supported</b> The Paterson 3D VRML model of the Cottesloe Syncline region in the northwest Paterson Orogen was created using 3D GeoModeller. 3D GeoModeller is an emerging technology that constructs 3D volumetric models based on a range of geological information. The principal benefit of 3D GeoModeller is that it provides geoscientists with a rapid tool for testing multiple working hypotheses. The models were built by members of the Paterson Project, as well as model building specialists within Geoscience Australia as a two-fold exercise. The primary purpose was to test the capabilities of 3D GeoModeller, while the secondary purpose was to evaluate the project's understanding of the 3D geology of the study area. Two 3D models of the Cottesloe Syncline were constructed, the first one utilising geological observations only from the geological map, and the other including the outcrop observations as well as an interpreted solid geology of the area. The resultant Cottesloe Syncline models, including two dimensional maps and images, were exported from 3D GeoModeller and transformed into Virtual Reality Modelling Language (VRML), enabling a wide audience to view the model using readily available software. For more information on how the Paterson Project used 3D GeoModeller to construct the Cottesloe Syncline model, see Constructing geologically-constrained 3D models using 3D GeoModeller. Geographic extent The Paterson Orogen is located in Western Australia and is situated between the Pilbara Craton to the southwest and the Canning Basin to the northeast. The Cottesloe Syncline 3D model covers an area of 30 x 35 km and is situated in the northwest of the Paterson Orogen. Content The Paterson 3D model and associated data sets consist of: a scanned image of the central portion of the Broadhurst 1:100 000 geological map sheet; an image of the Digital Elevation Model; input geological observations from the geological map; additional observations based on an interpreted solid geology; 3D surfaces of the various geological units based on the geological observations; and 3D surfaces based on the geological observations and the interpreted solid geology.
