  • The cartographic collection of the Doc Fisher Geoscience Library consists of the maps and air photos created or acquired by agency staff since the formation of BMR in 1946. This includes maps produced by agencies which have merged with these over the years, such as AUSLIG. Maps held include: Australian geological map series (1:250,000, 1:100,000 and the 1 mile series); topographic maps produced by NATMAP and its predecessors (1:250,000, 1:100,000 and 1:50,000) - latest editions only; various Australian geochemical, geophysical and other thematic maps; geoscience map series from other countries acquired on an exchange basis, including some with accompanying explanatory notes; Non-series maps acquired by donation or exchange; atlases. The Air photos are predominantly those used for mapping Australia and, to a lesser extent, Papua New Guinea and Antarctica, by BMR/AGSO from the 1940s to the 1980s. Geographical coverage of the sets is not complete, but many individual photos are unique in that they have pin points, overlays or other markings made by teams in the field. The Papua New Guinea photographs in the collection may, in many cases, be the only existing copies. Flight diagrams are also held for many (but not all) sets of air photos. Some other related materials, such as montages of aerial photographs (orthophotos), are also represented in the collection.

  • 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.

  • The Harris Greenstone Belt in the central Gawler Craton of South Australia has potential for Archaean Ni-Cu-PGE sulphide and Archaean-Proterozoic lode-Au mineralising systems. This map is a preliminary interpretation of the Precambrian basement geology based on aeromagnetics, gravity, and diamond drilling. It highlights the extensive distribution of poorly exposed Archaean komatiites and associated rocks (green) that have a strike extent of at least 300 km. The regional pattern of linear komatiitic sequences associated with ovoid granitic plutons and province-wide shear systems, is very similar to the economically important Eastern Goldfields Province in the Yilgarn Craton, Western Australia.

  • An interpretation of the Mulgathing Complex, a late Archaean high grade metamorphic complex in the northwest of the Gawler Craton, host to the Challenger Au deposit. This interpretation is based on gravity, drillhole and airborne magnetic datasets, ground reconnaissance and published geological maps. This map presents an interpretation of basement geology based on ground reconnaissance,interrogation of drill-hole databases, and interpretation of airborne magnetics, gravity data, and previous geological mapping: Benbow, M.C., 1981, COOBER PEDY 1:250 000 Geological Series SH53-6; Daly, S.J., 1985, TARCOOLA 1:250 000 Geological Series SH53-10; Benbow, M.C., 1986, TALLARINGA 1:250 000 Geological Series SH53-5; Benbow, M.C. et al., 1995, BARTON 1:250 000 Geological Series SH53-9; Vitols, V., 1974, COOBER PEDY 1:250 000 Geological Series SH53-6(Preliminary Edition). All the above authors from the Office of Minerals and Energy Resources, South Australia (or predecessors). The boundaries of some mapped units were modified to be consistent with geophysical data or ground truthing. As the map area is essentially under cover, the interpretation is necessarily broad and many anomalies remain uninterpreted. Granulite facies metamorphism has demagnetised much of the Mulgathing Complex and lithological packages, known to exist, could not be distinguished or differentiated. Areas where Palaeozoic cover has attenuated potential fields are shown. Gravity data come from 3851 stations out of a combined database of the Gawler Craton compiled by N.G. Direen (AGSO, unpublished data). These data comprise Commonwealth, State, and open file company surveys. Gravity data were converted to Simple Bouguer Anomalies at an S.G. of 2.67, according to the method of Wellman et al. (1985, BMR Record 261). Geodetic data were converted onto WGS84 and projected to MGA53. An ERMapper grid was produced in Intrepid using a multi-pass, variable density minimum curvature technique with a final grid cell size of 200 m. Intermediate gridding parameters included a coarse cell size of 21 km and a 32 cell extrapolation radius.

  • Gravity station location map, updated to October 2007

  • The product comprises digital outcrop geology and interpreted basement geology layers in ArcInfo, MapInfo and ArcView formats. The data were compiled from geological mapping of the Parkes 100K sheet from 1995 to 1998 by AGSO and the NSW Geological Survey under the NGMA. The data layers are a subset of the Forbes 250K sheet GIS data package.

  • A new digital surface geology dataset covering Australia at 1:1 million scale was released recently by Geoscience Australia. The digital map, which depicts geological units and structures seamlessly across state and territory borders, will provide an invaluable baseline dataset for national and regional evaluation of resources as well as environmental management and land use decision-making. This national project was undertaken with the full co-operation of the geological surveys of each Australian state and the Northern Territory who provided their most recent map data for the national compilation as well as their advice in resolving stratigraphic issues.

  • 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.

  • Displays the coverage of publicly available digital gamma-ray spectrometric data. The map legend is coloured according to the line spacing of the survey with broader line spacings (lower resolution surveys) displayed in lighter shades of blue and coral. Closer line spacings (higher resolution surveys are displayed in red, dark blue and purple.
