Application Description
ProvExplorer - Australian Geological Provinces Database
The ProvExplorer web application - http://www.ga.gov.au/provexplorer/frames.do - is a web-based map interface to the Australian Geological Provinces Database. The database contains descriptions and polygon outlines of geological provinces of the Australian continent and surrounding marine jurisdictional area. The provinces are mapped at a nominal 1:1 million scale.

In support of the annual offshore acreage release process, Geoscience Australia has, over the last six years, provided seismic data in a 'workstation ready' package to allow industry to load the data directly into their interpretation platforms saving considerable time and expense. These workstation packages are available in GeoFrame(TM)4.5, KingdomŪ8.5 formats and as exported segy with navigation in the headers ready for loading into any platform. This year data is split across two drives. The drives contain the relevant open-file 2D and 3D seismic and well information from the release areas. Well logs, well completion reports, destructive analysis reports and tiff images of scanned well log plots are included. Previously delivered limited interpretation over the North West Shelf for the 13 Geoscience Australia surveys are also included. The 2013 data package contains approximately 76,500 km2 of 3D and 524,900 kms of 2D. 2D projects have been divided into six main regional areas over the acreage and the workstation package has a variety of culture data loaded including well header data, bathymetric, magnetic and gravity grids as geo referenced tiffs. New seismic data for the 2013 release has been loaded primarily as 16 bit.

The physical properties of non-porous basement rocks are directly related to the mineralogy of those rocks. The MineralMapper3D software package originally developed by Nick Williams at the Predictive Mineral Discovery Cooperative Research Centre (pmd*CRC), Geoscience Australia, uses the physical properties of minerals to provide bounds on estimates of the abundance of specified minerals in non-porous basement rocks. This approach is applicable to both estimates of density and magnetic susceptibility derived from 3D inversions of gravity and magnetic data as well as physical measurements on specimens or down-hole derived physical properties.

View information on or download scanned images of all 1:250 000 scale geology maps of Australia. Images are available in 75 DPI, 125 DPI or 250 DPI resolution JPG files. Digital delivery of published (ie, cartographically produced) geological maps. When georeferenced, these images may be used as background information in GIS applications. Scanned image (eg, JPG), postscript, or PDF format published geological maps (including regolith, surface geology and solid geology) at all scales. This data may or may not be georeferenced.
Australian Stratigraphic Units Database
The Australian Stratigraphic Units Database (ASUD) is the national authority on stratigraphic names in Australia. It originated as the National Register of Stratigraphic Names in 1949. The register was originally set up to help geoscientists adhere to the then newly created Australian Code of Stratigraphic Nomenclature (Lenz, et al, 1996). All information was held in a card file system until 1979 when the database was first developed electronically. The database now records information on all Australian stratigraphic units and their usage in published literature. The database contains over 15000 currently approved stratigraphic names and over 30000 variations, most of which are superseded, obsolete, or misspelt versions of the current names. The database is maintained by Geoscience Australia on behalf of the Australian Stratigraphy Commission, a standing committee of the Geological Society of Australia. Data can be queried and downloaded at the ASUD website at http://www.ga.gov.au/oracle/stratnames/index.jsp.
