*** removed from website on advice from author *** 'Basins of Australia' map has been compiled as part of AGSO's studies of Australia's basins and continental margin. It shows outlines of all major sedimentary basins and sub-basins with their names both onshore and offshore. Outlines of sedimentary basins offshore were revised in 1995-96 to conform with new data/ideas on continental margin evolution and include volcanic margins features. The original compilation material included 44 published and unpublished contour maps (1977-1994) and 178 publications. The maps used for compilation varied in scale from 1:250 000 to 1:2 000 000, however, in some areas, where detailed maps were not available, small-scale maps (1:5 000 000 and even 1:10 000 000) were used to fill in the gaps. Large-scale maps have been generalised to conform to 1:6 000 000 scale of the final compilation. Most of the original maps reflected depth to basement (onshore basins, eastern and southern basins). In the absence of depth to the basement data, the deepest mapped horizon, or the horizon reflecting the main phase of rift basin development are portrayed (North West Shelf). The map shows outcrops of crystalline basement and Proterozoic basins. Different colour zones illustrate the age of oceanic crust. Plate tectonic elements, such as magnetic lineations, transform faults, continent-ocean boundary, subduction and collision zones are also included.

Geoscience Australia and the Office of Minerals and Energy Resources SA announce the release of digital point located and gridded gravity data from recent gravity surveys over the South Olympic, Lake Harris and Mulgathing regions of the Gawler Craton in South Australia. The data were acquired by Primary Industries and Resources South Australia (PIRSA) as part of its Targeted Exploration initiative South Australia (TEiSA) in collaboration with Geoscience Australia's Gawler Craton Mineral Promotion Project. Data collected during the survey provide the framework necessary for government and industry to assess resource potential, determine land use and environmental management policies, and aid in the planning of more detailed exploration activities. The survey comprises 3533 new gravity stations acquired over various station spacings. For the South Olympic region, stations were acquired on irregular 4 x 4 and 2 x 2 km grids. A regular 4 x 2 km grid was used in the Mulgathing region. In the Lake Harris region, data were acquired on a 4 x 1 km grid with a portion being infilled at 2 x 1 km, over the outcropping Lake Harris greenstone belt. Data were acquired over the period April to May 2001. The digital data are available from Geoscience Australia on CD-ROM. Contact the Sales Centre.
