Australian Diamond Deposits as of November 2006

GEODATA TOPO 5M 2004 is a seamless mapping data set at 1:5,000,000 scale which covers all of Australia. The data is particularly suited to national, state-wide and larger regional applications. This product is available in geo-referenced Portable Data Format (PDF) and provides a modern digital approach to the delivery and use of maps. PDF is a widely used format created by Adobe Systems which uses software to view the information. Topographic geoMAP 5 million PDF maps are available free online via Geoscience Australia`s Interactive Maps service.

This map image depicts a summary of the Australian 1:1 million scale digital geology dataset. The map image is designed for plotting at 1:5 million scale on A0 sized paper.

The Geology of Australia dataset documents the distribution and age of major stratigraphic, intrusive and medium to high-grade metamorphic rock units of onshore Australia. The data set was compiled to use at the 1:5,000,000 scale. The units distinguished/mapped mainly represent stratigraphic supergroups, regional intrusive associations and regional metamorphic complexes. This dataset is a generalised version of the 1:2,500,000 scale Geology (GEOMET No. 2305).

Two full-colour map sheets (at 1:5 million and 1:10 million scales) that show the continental extent and age relationships of Proterozoic mafic and ultramafic rocks and associated mineral deposits throughout the continent. These rocks have been assigned to 30 Magmatic Events (ME) ranging in age from the Early Palaeoproterozoic ~2455 Ma (ME 1) to the Early Cambrian ~520 Ma (ME 30). The presence and correlation of these Magmatic Events into five Major Crustal Elements and 28 provinces are represented in a Time-Space-Event Chart on Sheet 2. Enlarged inset maps on Sheet 1 provide in more detail the polygon and line data of certain regions, and other inset maps on Sheet 2 show the distribution of Proterozoic and Archaean rocks, mineral deposits and occurrences, and five Large Igneous Provinces (LIPs). This national map supersedes two similar 'Proterozoic Mafic-Ultramafic Magmatic Events' maps relating to Western Australia (2006; GeoCat 64813) and the Northern Territory-South Australia (2007; GeoCat 65257). A user guide to the map series is described in Geocat 66624. A georeferenced image of the map Australian Proterozoic Mafic-Ultramafic Magmatic Events (Sheet 1) is also provided. The image shows spatial distribution of Proterozoic (2500 Ma to 545 Ma) mafic-ultramafic magmatic events in Australia. The map illustrates for the first time, the continental extent and age relationships of Proterozoic mafic and ultramafic rocks and their associated mineral deposits. The image has been georeferenced using ESRI ArcGIS 9.3 software.
