  • 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, uranium and thorium. The data are collected on airborne geophysical surveys conducted by Commonwealth, State & NT Governments and the private sector.

  • This atlas brings together the latest geological ideas, incorporating earlier data gathered in the South Australian part of the basin, in an accessible form. The atlas consists of 30 plates covering a range of topics from topography and surface geology to water resources andpotential field data as well as the architecture of the basin fill. The atlas has been arranged to present some of the more general features of the basin such as topography, geology, structure and water resources in the earlier plates whilst concentrating on details of the basin fill in the later plates.

  • The Australian Geological Survey Organisation (AGSO) flew an airborne geophysical survey of 47 325 line km covering the Kingston 1:250 000 map Sheet area in the northern gold fields of Western Australia. The survey formed part of the National Geoscience Mapping Accord and was flown along north-south flight lines, 400 metres apart at an altitude of 80 metres above ground level. AGSO flew the survey from 15 July to 29 August 1998. The total magnetic intensity, gamma-ray spectrometric and digital elevation model data collected during the survey, have been processed and are available for purchase. These data are sold as digital point located data, grids and hardcopy maps by the Australian Geological Survey Organisation. Colour and greyscale pixel image maps are also available.

  • The Australian Geological Survey Organisation (AGSO) flew an airborne geophysical survey of 55,233 line kilometres over the Thackaringa and Redan 1:100 000 map Sheet areas on the Menindee 1:250 000 map Sheet area from 8 June to 5 August 1995. The survey was flown as part of the Broken Hill Exploration Initiative, a National Geoscience Mapping Accord project implemented by AGSO, the New South Wales Department of Mineral Resources and the Department of Minerals and Energy South Australia. The survey was flown along east-west flight lines spaced mainly 100 m apart (200 m in some areas) at a nominal altitude of 60 m above ground level. The total magnetic intensity, gamma-ray spectrometric and digital elevation model data which were collected during the survey, have been processed and are available for purchase, in both digital (point located data and gridded) and map form, from the Australian Geological Survey Organisation.

  • This record summarises the basement-related studies undertaken in the NABRE project. It includes various transformations of the north Australian regional aeromagnetics and gravity datasets, estimates of depths to magnetic sources for northern Australia, and eight regional traverse models for the region.

  • The Forbes Geology GIS comprises a digital compilation of regional geological mapping of the Forbes 1:250,000 sheet by AGSO and the NSW DMR under the National Geoscience Mapping Accord from 1995 to 1999. The data package includes all mapping data from the 6 component 1:100,000 geological sheets; Parkes, Grenfell, Bogan Gate, Marsden, Condobolin and Wyalong. The GIS includes polygon and line layers depicting outcropping and buried rock types, structures, and regolith landforms. It also includes point layers depicting outcrop descriptions; mineral occurrences; geochemical, thin section and geochronological samples; georeferenced photographs; structural readings; and drill hole locations. Images of AGSO's airborne magnetic and radiometric data, and a depth to slightly weathered bedrock model are included.
