  • Two colour maps sheets at 1:5 million, 1:7.5 million and 1:15 million scale show the continental extent of Proterozoic Large Igneous Provinces and other mafic-ultramafic magmatic events, and their relationships to the Australian Crustal Elements. A time series shows the evolution of location controls on mafic-ultramafic magmatism from 2500-500 Ma. Polugons and linework are derived, with modifications, from the 'Map of Australian Proterozoic mafic-ultramafic magmatic events' (Hoatson, Claoue-Long & Jaireth 2008). <h3>Related products:</h3><a href="https://www.ga.gov.au/products/servlet/controller?event=GEOCAT_DETAILS&amp;catno=70008">Guide to using the Map of Australian Proterozoic Large Igneous Provinces</a> <a href="https://www.ga.gov.au/products/servlet/controller?event=GEOCAT_DETAILS&amp;catno=70461">Proterozoic Mafic-Ultramafic Magmatic Events Resource Package</a> <a href="https://www.ga.gov.au/products/servlet/controller?event=GEOCAT_DETAILS&amp;catno=66114">Australian Proterozoic Mafic-Ultramafic Magmatic Events: Map Sheets 1 and 2</a> <a href="https://www.ga.gov.au/products/servlet/controller?event=GEOCAT_DETAILS&amp;catno=66624">Guide to Using the Australian Proterozoic Mafic-Ultramafic Magmatic Events Map</a> <a href="https://www.ga.gov.au/products/servlet/controller?event=GEOCAT_DETAILS&amp;catno=69347">Archean Mafic-Ultramafic Magmatic Events Resource Package</a> <a href="https://www.ga.gov.au/products/servlet/controller?event=GEOCAT_DETAILS&amp;catno=69935">Guide to using the Australian Archean Mafic-Ultramafic Magmatic Events Map</a>

  • A monthly archive of data from the GAV section

  • Release of the Cariewerloo Traverses of the Frome AEM Survey. These traverses were funded by the Department of Primary Industry and Resources South Australia (PIRSA).

  • Bushfire Attack Level (BAL) project is collaboration between Geoscience Australia and Department of Fire Emergency Services (DFES), Western Australia. GA has developed and delivered products including toolbox, maps, data and user guide to DEFS to compute the bushfire attack level. This archive includes all documents, data, maps, scripts, etc. for this project.

  • Data to support the Wallaby Plateau GA Record 13-7113. This includes: 1. Magnetic modelling input data and model results 2. Gravity modelling input data and model results 3. Dredge sample rock properties associated with the Wallaby Plateau

  • These data have been generated by a high resolution climate Model using 6 drivers as specified in the file name. The model simulations cover the period 1960-2100. The data contains a large number of variables, for wind hazard studies the wind-related variables should be extracted. Author: CSIRO's CCAM high resolution model team Geographic extend: The simulations focus on Australia's climate Conditions using a cubic-conformal grid, the coarse part is used In places other than Australia (World).

  • A three-dimensional (3D) map of the Cooper Basin region has been produced from 3D inversions of Bouguer gravity data using geological data to constrain the inversions. The 3D map has been used to predict temperatures and their uncertainty throughout the volume of the map. This will allow regions of elevated predicted temperature at 4-5 km to be identified, which may provide targets for future geothermal exploration in the Cooper Basin region. The 3D map delineates regions of low density within the basement of the Cooper and Eromanga basins that are inferred to be granitic bodies, which may act as heat sources. It also delineates the stratigraphy of the sedimentary basins which act as thermal insulation. This release is the second version of the 3D map of the Cooper Basin region. It builds on Version 1 of the Cooper Basin Region Geological map, released in 2009.

  • MAGSHOW is a suite of computer programs for AGRF90 together with several associated utilities. This particular program, SHOW, provides an interface for AGRF90 plus the capability of 3D dynamic graphics display of grids of any element of the geomagnetic field over Australia. (Now obselete.)

  • The Dynamic Land Cover Dataset of Australia is the first nationally consistent and thematically comprehensive land cover reference for Australia. It is the result of a collaboration between Geoscience Australia and the Australian Bureau of Agriculture and Resource Economics and Sciences, and provides a base-line for identifying and reporting on change and trends in vegetation cover and extent. The dataset comprises digital files of the land cover classification, three trend datasets showing the change in behaviour of land cover across Australia for the period 2000 to 2008 and a digital copy of the technical report.

  • These data represent the January 2002 edition of the Magnetic Anomaly Grid of the Australian Region. This version is the first integrated onshore/offshore magnetic anomaly grid for the complete Australian margin extending across 8S - 52S, 106E - 172E. The grid cell size is 0.01 degree (approx. 1 km). Earlier releases were restricted to portions of NW and SW Australia. - Magnetic anomaly unit is nanoTesla (nT). Appropriate IGRFs have been removed. Horizontal datum is GDA94 (which is equivalent to WGS84). - The marine data were levelled independently of the onshore data in three sectors (see below). The NNW and SSW sectors were released as grids previously. The eastern sector was levelled in 2000 in collaboration with Intrepid Geophysics (Melbourne, Australia). The three levelled sectors, together with the unlevelled sectors were combined with the onshore grid to give the present grid. Altogether, 3,022,656 data points are in the database from which the marine grid was created. - Unlevelled sectors: (-8 -25 160 172), (-39 -52 156 172), (-46 -52 106 140) - Levelled sectors: (-37 -52 140 156), (-25 -39 143 172), (-8 -25 143 160), (-24 -46 106 140), (-8 -24 106 143) - There are several places at the join between onshore and offshore grids where the two grids do not match. The problem exists because the onshore grid was developed earlier, and there was poor control on the grid merging process at the margins. Future work will attempt to address this issue and improve the continuity between the onshore and offshore grids.
