The Geology of Australia data set documents the distribution and age of major stratigraphic, intrusive and medium to high-grade metamorphic rock units of onshore Australia. It is an ongoing compilation, subject to periodic revision as additional data becomes available. The data set was compiled to use at scales between 1:2,500,000 and 1:5,000,000 inclusive.

Tasman South East Fold Belt Stratotectonic and Structural Elements

The data is a cropped portion of the generalised geology of Western Australia. The generalised geology contains geoscience data covering themes such as geology and tectonic boundaries. The data is held in GDA decimal degrees.

Geoscience Australia's wall map of Australia is ideal for displays and feature walls in offices, classrooms and conference rooms. The four component sheets - North-East, North-West, South-East and South-West are available individually, with each map 103cm x 88cm. The fully assembled size is 2m x 1.7m. At this scale 1cm on the map represents 25km on the ground. Product Specifications Coverage: Complete coverage of Australia Currency: Last revised 2011 Coordinates: Geographical Datum: AGD66 (GDA94 compliant at this scale); AHD Projection: Simple Conic on two standard parallels (18S and 36S)

This map shows the area of the Eastern South Australia Trawl Closure within the Commonwealth Trawl Sector (also known as the South East Trawl Fishery (SETF)) of the Southern and Eastern Scalefish and Shark Fishery. Developed as per the Southern and Eastern Scalefish and Shark Fishery (Closures) Direction 2008 - Schedule 22. Produced for the Australian Fisheries Management Authority. Not for public sale or distribution by GA.

A weathering intensity index (WII) over the Australian continent has been developed at a 100 m resolution using regression models based on airborne gamma-ray spectrometry imagery and the Shuttle Radar Topography Mission (SRTM) elevation data. Airborne gamma-ray spectrometry measures the concentration of three radioelements - potassium (K), thorium (Th) and uranium (U) at the Earth's surface. The total gamma-ray -ux (dose) is also calculated based on the weighted additions of the three radioelements. Regolith accounts for over 85% of the Australian land area and has a major in-uence in determining the composition of surface materials and in controlling hydrological and geomorphological processes. The application of a stepwise forward multiple regression for the second model generated a weathering intensity index equation of: WII = 6.751 + ? 0.851 - K+ ? 1.319 ? Relief + 2.682 - Th/K + ? 2.590 - Dose. The WII has been developed for erosional landscapes but also has the potential to inform on deposition processes and materials. Interpretation of the WII from regional to local scales and its application in providing more reliable and spatially explicit information on regolith properties are described.
