  • This map is part of a series which comprises 50 maps which covers the whole of Australia at a scale of 1:1 000 000 (1cm on a map represents 10km on the ground). Each standard map covers an area of 6 degrees longitude by 4 degrees latitude or about 590 kilometres east to west and about 440 kilometres from north to south. These maps depict natural and constructed features including transport infrastructure (roads, railway airports), hydrography, contours, hypsometric and bathymetric layers, localities and some administrative boundaries, making this a useful general reference map.

  • Digital Geology and Lithology maps of the Strangways Range Region in the eastern Arunta Region of the Northern Territory have been produced from a scanned image of the first edition map published by the Bureau of Mineral Resources in 1984. The image was digitised using Microstation and ArcInfo software, and attributed to meet standards for Version 2004.01 of the Geoscience Australia Digital Data Dictionary for GIS Produces as closely as possible. The finished product has been provided as ArcView shape files and ArcInfo export files on CD-ROM. Extensive internal quality assurance and quality control processes have been used to verify the data.

  • At this scale 1cm on the map represents 1km on the ground. Each map covers a minimum area of 0.5 degrees longitude by 0.5 degrees latitude or about 54 kilometres by 54 kilometres. The contour interval is 20 metres. Many maps are supplemented by hill shading. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours, localities and some administrative boundaries. Product Specifications Coverage: Australia is covered by more than 3000 x 1:100 000 scale maps, of which 1600 have been published as printed maps. Unpublished maps are available as compilations. Currency: Ranges from 1961 to 2009. Average 1997. Coordinates: Geographical and either AMG or MGA coordinates. Datum: AGD66, GDA94; AHD Projection: Universal Transverse Mercator UTM. Medium: Printed maps: Paper, flat and folded copies. Compilations: Paper or film, flat copies only.

  • Geoscience Australia has produced digital geological and lithology maps of the Arltunga-Harts Range Region in the eastern Arunta Region of the Northern Territory using a scanned image of the first edition hardcopy map published by the Bureau of Mineral Resources in 1984. The image was digitised using Microstation and ArcInfo software, and attributed to meet the Version 2004.01 of the Geoscience Australia Digital Data Dictionary for GIS Products as closely as possible. The finished product has been provided as ArcView shape files and ArcInfo coverages on CD-ROM. Extensive internal quality assurance and control has been perfomed on the layers.

  • A snapshot of the latest interpretation of the basement geology based primarily on airborne geophysics and drillhole logging. The Moonta Domain forms the southern part of the Olympic Cu-Au province on the eastern margin of the Gawler Craton, and underlies most of the Yorke Peninsula and Spencer Gulf. The domain basement comprises metasediments and metavolcanics of the Palaeoproterozoic Wallaroo Group (~1760-1740 Ma) which were deformed and metamorphosed to upper greenschist-amphibolite facies during the Kimban Orogeny (~1720 Ma). These rocks were further deformed and intruded by granitoids and minor mafic intrusions of the Hiltaba Suite between about 1600 Ma and 1575 Ma. The Moonta Domain basement is highly prospective for iron oxide-Cu-Au mineralisation associated with the Hiltaba magmatic event. However outcrop of these basement rocks is limited almost entirely to narrow coastal exposures. The majority of the prospective basement is concealed by up to 100 metres of Neoproterozoic to Quaternary sediments, and geological mapping of the basement is largely limited to interpretation of geophysics (airborne magnetics, gravity, AEM) and drilling.

  • Igneous rocks have long been recognised as an important source of metals in uranium mineral systems. Although magmas may form mineral deposits in their own right, they may also contribute directly to basin-related mineral systems as a source of metals and/or ligands. Thus, mapping of the distribution of uranium in igneous rocks has the potential to highlight potentially prospective regions for uranium mineralisation at a macro-scale. Map 2 in the series of three maps of the uranium content of Australian igneous rocks shows polygons of igneous rock distribution, derived from the Geoscience Australia 1:1,000,000 national surface geology dataset. Polygons are coloured by their average uranium content. The average uranium content of each polygon was calculated by plotting the igneous polygons together with geochemical sample points (distribution shown in Map 1 of the series) using ArcGIS software. Each polygon was then attributed with the average uranium value (in ppm) of all intersecting geochemical sample points. This approach allows igneous uranium content to be assessed on the pluton- to province-scale, depending on polygon resolution. Together with the two other maps in the series, this map demonstrates the close spatial relationship between uranium-rich igneous rocks and areas of known uranium mineralisation. In addition, new regions previously unknown for uranium mineralisation can be identified.
