Abstract
*** 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 The original compilation material included 44 published and unpublished contour maps (1977-1994) and 178 publications.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.
