Relative petroleum prospectivity of the North-west marine planning region.

This dataset is a subset of the Sedimentary Basins dataset developed by Geoscience Australia. It represents those sedimentary basins in the North-west commonwealth marine planning region that are considered to be prospective for petroleum, and it has been attributed with a rating describing the relative prospectivity of different areas. This interpretive data on relative petroleum prospectivity is derived from Geoscience Australia's internal quantitative basin evaluation work, modified in some cases after consultation with their own internal experts on particular basins. The classification terms used represent a simplified qualitative assessment of petroleum prospectivity, and are subject to future change as new data are gathered and interpreted.

The information has been provided to DEWHA in good faith, as an input to bioregional marine planning and MPA development in the North-west marine planning region. It should not be taken as a definitive Geoscience Australia view of the petroleum prospectivity of these areas.

The Sedimentary Basins dataset itself provides outlines for the maximum extent of Australian geological provinces and their components, including sedimentary, igneous, metamorphic provinces, both onshore and offshore. These data were compiled as part of Geoscience Australia's integrated digital information system to provide improved accessibility and knowledge relating to the petroleum and minerals geology and prospectivity, and to provide a national stratigraphic and tectonic framework for Australia. The current Sedimentary Basins dataset is not complete for Australia, and covers only offshore sedimentary provinces and a selection of sedimentary and igneous provinces in onshore eastern Australia.The information has been provided to DEWHA in good faith, as an input to bioregional marine planning and MPA development in the North-west marine planning region. It should not be taken as a definitive Geoscience Australia view of the petroleum prospectivity of these areas.

The following caveat applies to the use of the data in any mapping products: 'The interpretive data on relative petroleum prospectivity are derived from Geoscience Australia's internal quantitative basin evaluation work, modified in some cases after consultation with their own internal experts on particular basins.
