Map which identifies Australia's diamond deposits, kimberlites, and related rock locations overlaying the 'Magnetic Anomaly Map' image. Includes photo images of major mine fields, and pie charts depicting Australia's diamond production and value in $US against world data. Information compiled from different sources, including mining companies, mining journals and 'Magnetic Anomaly Map'

Contains boundary and attribute information for parcels of public, private and Aboriginal lands in Australia. Data are sourced primarly from government gazette notices, cadastral maps and plans. A nominal scale of around 1:5 million and a minimum 50 square kilometre threshold limit for land parcels was used in the generalisation of this product from the National Public and Aboriginal Lands data. Data is suitable for GIS applications. This map shows public and private land tenure, including Indigenous land for the whole of Australia at a scale of 1:4.7 million. The land tenure boundaries depicted on this map generally define broadly classified areas greater than 50 square kilometres. Indigenous land areas between 0.1 and 100 square kilometres are shown more comprehensively by symbols. The information on this map is complemented by statistical tables giving the total area of the land tenure categories for each State and Territory. This map is also available as free vector GIS data, ArcInfo Export, ArcView Shapefile and MapInfo mid/mif. Please direct any corrections or feedback on this map to mapfeedback@ga.gov.au.

Australia has been divided into 392 Regolith Terrain Units on the basis of dominant topography, geology and regolith. Full details available in BMR Record 1986/27 has been used to attribute this dataset.

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 the Australian Government'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 100 m 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 and can be purchased as an A0 printed wall map from our Sales Centre. 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.

This dataset represents the distribution of Petroleum titles for the Australasian region. This attributed dataset is used in production of the "Petroleum Exploration and Development Titles" map published annually in APRIL. Attributes and an additional lookup table contain information on the operator, dates of award and expiry, the State who has jurisdiction, and the companies and their equity for each title.
