This dataset is derived from the 1:2,500,000 scale geology of Australia (1976).The surficial cover theme was derived from stipple patterns on the original published maps, overprinting the bedrock geology polygons. It has polygon topology with attribution giving a description and a numerical code for each map unit. Map units represent 5 superficial Cainozoic units and exposed bedrock. The data was originally captured by AGSO and passed to NRIC (now ARDC) for translating, cleaning and final editing. ARDC acknowledges the following organisations for their contributions to the preparation of this dataset: Australian Geological Survey Organisation (AGSO) Australian National Parks and Wildlife Service (project initiation and financial support) This digital dataset was released in 1999 by ARDC, BRS.

Layer 08B Base of Poolowanna Formation Surface produced for the Great Artesian Water Resource Assessment (GABWRA) by Geoscience Australia (http://www.ga.gov.au). This surface was created for 3D visualisation of the Base of Poolowanna Formation . The surface is available in the following formats 1. GOCAD surface (.ts) 2. ESRI grid 3. ASCII grid (.grd) Use limitations: 1. GOCAD surface requires program capable of reading GOCAD *.ts (triangulated surface) files 2. ASCII grid data requires re-interpolation by end-user resulting in minor differences to accompanying GOCAD *.ts surface This layer is part of a set comprised of: Layer 01 3-second Digital Elevation Model surface (catalogue #75990) Layer 02 Base of Cenozoic surface (catalogue #75991) Layer 03 Base of Mackunda Formation and equivalents surface (catalogue #76021) Layer 04 Base of Rolling Downs Group surface (catalogue #76022) Layer 05 Base of Hooray Sandstone and equivalents surface (catalogue #76023) Layer 06 Base of Injune Creek Group surface (catalogue #76024) Layer 07 Base of Hutton Sandstone surface (catalogue #76025) Layer 05-07 Base of Algebuckina Sandstone surface (catalogue #76952) Layer 08A Base of Evergreen and Marburg formations (catalogue #76026) Layer 08B Base of Poolowanna Formation (catalogue #76953) Layer 09 Base of Precipice Sandstone and equivalents surface (catalogue #76027) Layer 10 Base of Jurassic-Cretaceous sequence surface (catalogue #76028) This dataset and associated metadata can be obtained from www.ga.gov.au, using catalogue number 76953.

This map shows the area of the Portland Area Trawl Closure within the Commonwealth Trawl Sector (also known as the Commonwealth South East Trawl Fishery (SETF)) of the Southern and Eastern Scalefish and Shark Fishery. Modified from GeoCat 68493 (2008) as per the Southern and Eastern Scalefish and Shark Fishery (Closures) Direction No. 1 2009 - Schedule 23. Produced for the Australian Fisheries Management Authority. Not for public sale or distribution by GA.

Pixel map image of the Pilbara area. Composite colour image of K (red), U (blue) and Th (green). Each band histogram equalised. 25% of total count added as a gradient to enhance the visibility of small scale structures.

The Mineral Deposits Map of Papua New Guinea has been compiled jointly by the Bureau of Mineral Resources (BMR) and the Geological Survey of Papua New Guinea. Open-file data have been used in the compilation of the map, which is envisaged as an aid to exploration and for official purposes; it is not intended to be a metallogenic map. Metals, mineral fuels, and industrial minerals are plotted but construction and fluxing materials and groundwater are excluded. The commodities in the map and tables are present in, or have been extracted from, each deposit as shown, and the importance of the deposit has been assessed on available information. The notes supplement the map by providing detailed information on each commodity. They are organized into sections which correspond to the commodity groups discussed below, and within each section the data on individual commodities are present in tabular form. Appendix II lists the commodities occurring in each Papua New Guinea 1:250 000 Sheet area. Figure 1 is a reference map of the Sheet areas.

The 1:2 500 000 scale bedrock geology map of Queensland and northwest New South Wales was compiled at 1:500 000 scale, primarily based on the 1:2 000 000 surface geology map of Queensland Geology (2012) by removing unconsolidated Cenozoic sediments with interpretation of aeromagnetic data and reference to Geological Survey of New South Wales' interpretation of the Thomson Orogen region (Hegarty 2010). This work also referred to the geological province work by Stewart et al (2013). Stratigraphic unit definition data is linked to the Australian Stratigraphic Names Database through the stratno, by which this bedrock geology map may also be linked to other geoscientific databases housed in Geoscience Australia.
