Australia magnetic map 1:2.5m

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.

Layer 01 3-second Digital Elevation Model surface 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 3 second DEM The surface is in the following format 1. GOCAD surface Use limitations: 1. GOCAD surface requires program capable of reading GOCAD *.ts (triangulated surface) files. 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 75990.

A legacy of over 500 paper maps records geological lineament analysis of Australia conducted by the late Tim O'Driscoll in Western Mining Corporation Exploration Division during the 1960s to 1980s. The lineament interpretations were used to target mineral exploration, famously including the analysis that led to the discovery of the Olympic Dam deposit in South Australia. Papers discussing the lineament approach are collected in Bourne & Twidale (2007). Lineaments were interpreted from a range of data available at the time, including magnetic and gravity maps, topography, standard geological maps, and 'chicken track'interpretation of aerial photographs and early satellite images. This product comprises high quality digital scans of 130 of the original paper maps, rectified and georeferenced for use in GIS software. Geoscience Australia reproduces these maps and makes them available publicly for their historic and scientific interest. The paper originals are held in the Geoscience Australia library.

The map represents the Tasman Fold Belt System by a set of Stratotectonic Stages, the oldest, in Tasmania, being Mesoproterozoic and the youngest, in Queensland, Jurassic-Cretaceous. Each Stage is chiefly an assemblage of lithofacies elements that taken together, represent a major episode in the tectonic evolution of the System. The boundaries of Stages and elements are commonly unconformities or seperate significantly different facies. Most Stage boundaries are time-transgressive. Stratotectonic Stages and their age ranges are shown on the map by Stage numbers.
