This is the first release of stream sediment geochemical data covering most of the outcropping portion of the Mesoproterozoic Croydon Province in north Queensland. This product contains ASCII data files containing sample number, sample site location and element values.

To assist the mining industry during the current buoyant times of historically high nickel and platinum-group element prices, Geoscience Australia has produced two web-based map sheets (at 1:5 million and 1:10 million scales) that show the spatial distribution of Proterozoic (2500 Ma to 545 Ma) mafic-ultramafic magmatic events in Australia. The maps illustrate for the first time, the continental extent and age relationships of Proterozoic mafic and ultramafic rocks and their associated mineral deposits. These rocks have been assigned to thirty Magmatic Events (ME) that range in age from the Early Palaeoproterozoic ~2455 Ma (ME 1) to the Early Cambrian ~520 Ma (ME 30). Resource package contains: - Australian Proterozoic Mafic-Ultramafic Magmatic Events: Map Sheets 1 and 2 - Guide to Using the Australian Proterozoic Mafic-Ultramafic Magmatic Events Map - Spreadsheets of data that support the maps - A time series animation summarising all the mafic-ultramafic magmatic events

When the PMDCRC project concluded at Geoscience Australia, some data was left unsorted. This directory contains that residual data. In 2001, a partnership was formed between Australia's mining industry and research community to examine the issues surrounding predictive mineral exploration in Australia. In the preceding decade, despite record levels of exploration, the discovery of high level deposits declined. The predictive mineral discovery Cooperative Research Centre (pmd *CRC ) began its work to find new methods of predicting where the mineral deposits lay. The research looked to create a fundamental shift in mineral exploration practice giving greater scope for larger finds at greatly reduced costs by developing a vastly improved understanding of mineralising processes and a four dimensional understanding of the evolution of the geology of mineralised terrains. Since its inception, research has been carried out by the CRC through innovative and effective programs and projects over a two stage process. This website will act as a major portal for the dissemination of research findings. As well it offers the mining industry, the education sector and the wider community information and access to experts in the field, case studies of successful programs, business opportunities and employment directions for young emerging students and researchers. The pmd *CRC formally ceased to exist on 30 June 2008

Between October 2008 and February 2009, Geoscience Australia undertook two major surveys off the coast of Western Australia. Areas of interest included the Mentelle and northern Perth Basins, the Southern Carnarvon Basin, the southern Exmouth Sub-basin (Northern Carnarvon Basin) and the Wallaby Plateau. These surveys collected a range of data, including industry-standard seismic reflection data and gravity and magnetic data. In addition to the new data collected, Geoscience Australia has reprocessed existing open file 2D seismic data within the survey area. These data are available for purchase. Please complete the order form on the downloadable information sheet and return to Geoscience Australia.

Airborne Electromagnetic data are being acquired by Geoscience Australia in areas considered to have potential for uranium or thorium mineralisation under the Australian Government's Onshore Energy Security Program (OESP). The surveys have been managed and interpreted by Geoscience Australia's Airborne Electromagnetic Acquisition and Interpretation project. In contrast to industry style deposit scale investigations, these surveys are designed to reveal new geological information at regional scale. The Paterson airborne electromagnetic data were acquired at line spacings of between one and six kilometres, a total of 28 200 line km and covers an area of 47 600 km². The outcomes of the Paterson AEM survey include mapping of subsurface geological features that are associated with unconformity-related, sandstone-hosted and palaeovalley-hosted uranium mineralisation. The data are also capable of interpretation for other commodities including metals and potable water as well as for landscape evolution studies. The improved understanding of the regional geology resulting from the Paterson survey results will be of considerable benefit to mining and mineral exploration companies. This Data Package is for Archive to the internal area of the CDS and contains all data, grids, images, mxd, shape files, documentation, licenses, agreements, interpretations and scripts used to create the Paterson deliverables. At the projects completion (2012) all directories are required to be moved off the NAS. The reason to keep all the files is that more work is to be done on this data in the 2012-2015 period and these files may be needed in this future work.

From 1995 to 2000 information from the federal and state governments was compiled for Comprehensive Regional Assessments (CRA), which formed the basis for Regional Forest Agreements (RFA) that identified areas for conservation to meet targets agreed by the Commonwealth Government with the United Nations. These 3 CDs were created as part of GA's contribution to the Tasmania CRA. CD1 contains final versions of all data coverages and shapefiles used in the project, and final versions of documents provided for publishing. CD2 contains Published Graphics files in ArcInfo (.gra), postscript (.ps) and Web ready (.gif) formats. CD3 contains all Geophysical Images and Landsat data.

From 1995 to 2000 information from the federal and state governments was compiled for Comprehensive Regional Assessments (CRA), which formed the basis for Regional Forest Agreements (RFA) that identified areas for conservation to meet targets agreed by the Commonwealth Government with the United Nations. These 5 CDs were created as part of GA's contribution to the SE Queensland CRA. CD1 contains ArcView Legends and Projects, data coverages, shapefiles, all documents and reports and associated maps and figures. CD2 contains various edited versions of covers and shapefiles, original data supplied by custodians, and staff workareas. CD3 contains Landsat, Magnetics etc. images. CD4 contains DEM etc. CD5 contains integration data, miscellaneous ArcInfo grids, and ArcInfo graphic files.
