  • 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 Pine Creek AEM survey was flown over the Pine Creek Orogen in the Northern Territory during 2008 and 2009 as part of the Australian Government's Onshore Energy Security Program at Geoscience Australia (GA). The survey covers an area of 74,000 km2 from Darwin to Katherine in the Northern Territory which hosts several world class deposits, including the Ranger Uranium Mine, Nabarlek, Mt Todd, Moline and Cosmo Howley. Aimed at regional mapping, uranium exploration, reducing exploration risk and promoting exploration activity, the program worked closely with industry partners to infill wide regional line spacing (5km) with deposit scale line spacing (less than 1km). The survey results are relevant in exploration for a variety of commodities and resources, including uranium, copper, lead, zinc, gold, nickel and groundwater. Geoscience Australia's interpretation products include sample-by-sample layered earth inversion products comprising located data, geo-located conductivity depth sections, depth slice grids, elevation slice grids, inversion report and an interpretation report. All data and products are available from GA as well as the Northern Territory Geological Survey Geophysical Image Web Server.

  • Validation of spectral remote sensing data for geological mapping and detection of hydrothermal footprints in the Mount Isa Inlier

  • Geoscience Australia often produces spatially continuous marine environmental information products using spatial interpolation methods. The accuracy of such information is critical for well-informed decisions for marine environmental management and conservation. Improving the accuracy of these data products by searching for robust methods is essential, but it is a vexed task since no method is best for all variables. Therefore, we experimentally compared the performance of 32 methods/sub-methods using seabed gravel content data from the Australian continental EEZ. In this study, we have identified and developed several novel and robust methods that significantly increase the accuracy of interpolated spatial information. Moreover, these methods can be applied to various environmental properties in both marine and terrestrial disciplines.

  • This report describes the geology of the area covered by the SKIPTON 1:100 000 sheet area (7522) in western Victoria. Geomorphology, stratigraphy, structure, metamorphism and economic geology of the area are described. Brief outlines of the regional geological setting and geological history are also presented. The Skipton 1:100 000 sheet area comprises an inlier of early Palaeozoic meta-sediments and intrusives, unconformably overlain by surficial Cainozoic sediments and volcanics. The exposed bedrock forms the westernmost part of the Lachlan Fold Belt. Exposed bedrock comprises Cambrian-Ordovician turbidites of the Warrak and Pyrenees Formations of the Saint Arnaud Group. These units were deformed and regionally metamorphosed to low-grade during the Silurian Benambran deformation and later intruded by Devonian fractionated I-type granite plutons. A transgressive fluviatile to marine sequence of Tertiary rocks overlies older units in the centre and west: units distinguished are the White Hills Gravel, Dilwyn Formation, Heytesbury Group and Moorabool Viaduct Sand. Quaternary units cover most of the sheet area and comprise basalt flows and scoria deposits of the Newer Volcanics, and a range of fluvial and lacustrine sediments including: older alluvial terrace deposits; older alluvial and colluvial deposits; colluvial deposits; swamp and lagoonal deposits; stream alluvial deposits; and lunette deposits. Late Pleistocene aeolian clay, the Windgelli Clay, forms a thin veneer over the most of the Palaeozoic rocks and the Newer Volcanics. The previously worked tungsten, gold, bismuth and silver - bearing vein deposit at Pittong is the only metalliferous occurrence known in SKIPTON. However, the area contains more significant nonmetalliferous deposits including the Pittong clay deposit and deposits of sand, granite, basalt, and scoria.
