  • Joint Release of the National ASTER geoscience maps at IGC The ASTER (Advanced Spaceborne Thermal Emission and Reflectance Radiometer) Geoscience Maps are the first public, web-accessible, continent-scale product release from the ASTER Global Mapping data archive. The collaborative Australian ASTER Initiative represents a successful multi-agency endeavour, led by the Western Australian Centre of Excellence for 3D Mineral Mapping (C3DMM) at CSIRO, Geoscience Australia and the State and Territory government geological surveys of Australia, along with other national and international collaborators. National ASTER geoscience map These geoscience maps are released in GIS format as 1:1M map-sheet tiles, from 3,000 ASTER scenes of 60x60km. Each scene was cross-calibrated and validated using independent Hyperion satellite imagery. The new ASTER geoscience products range in their application from local to continental scales, and their uses include mapping of soils for agricultural and environmental management, such as estimating soil loss, dust management and water catchment modelling. They will also be useful for resource exploration, showing host rock, alteration and regolith mineralogy and providing new mineral information at high spatial resolution (30m pixel). This information is not currently available from other pre-competitive geoscience data.

  • A collection of mining and explotation tenements supplied by the individual state and territory bodies. Loaded monthly to an Oracle database from shapefiles given to Geoscience Australia.

  • This study brings together a wide range of datasets to provide a comprehensive assessment of the Pandurra Formation sedimentology and geochemistry in 3D. This record is associated with both the GA Record and the digitial data release. Sedimentology and geochemistry datasets generated this study are combined with pre-existing data to generate a 3D interpretation of the Pandurra Formation and improve understanding of how the Pandurra Formation as we see it today was deposited and subsequently post-depositionally mineralised. The digital release incorporates the underlying digital data generated this study, the final gOcad objects generated, and reference datasets from Wilson et al., 2011 as required. Study extent in eastings and northings: SW Corner (444200, 6263000) NE Corner (791409, 6726000).

  • The rare-earth elements (REE) are a group of seventeen speciality metals that have unique and diverse chemical, magnetic, and luminescent properties that make them strategically important in a number of high-technology industries. Consequently, the REE are increasingly becoming more attractive commodity targets for the mineral industry. This paper presents a comprehensive review of the distribution, geological characteristics and resources of Australia's major REE deposits. REE in Australia are associated with igneous, sedimentary, and metamorphic rocks in a wide range of geological environments. Elevated concentrations of these elements have been documented in various heavy-mineral sand deposits (beach, dune, marine tidal, and channel), carbonatite intrusions, (per)alkaline igneous rocks, iron-oxide breccia complexes, calc-silicate rocks (skarns), fluorapatite veins, pegmatites, phosphorites, fluviatile sandstones, unconformity-related uranium deposits, and lignites. The distribution and concentration of REE in these deposits are influenced by various rock-forming processes including enrichment in magmatic or hydrothermal fluids, separation into mineral species and precipitation, and subsequent redistribution and concentration through weathering and other surface processes. The lanthanide series of REE (lanthanum to lutetium) and yttrium, show a close genetic and spatial association with alkaline felsic igneous rocks, however, scandium in laterite profiles has a closer affinity with ultramafic/mafic igneous rocks.

  • During the Mullins Harbour - Wedau Reconnaissance (South Eastern Papua) carried [out] in 1953 by Mr. J.E. Thompson, Senior Geologist of the Bureau of Mineral Resources, a section was sampled along the Middle Nigo-Nigo River. Of a number of samples sent to Canberra for petrological and palaeontological examination only eight proved fossiliferous. The following is a list of samples examined listing lithology and microfauna determined by the author and the age assigned to each.

  • The following report concerns the geology and mineralization of two uranium prospects in the Gimbat - Snake Creek Area of the Northern Territory. One of these prospects, referred to as Sleisbeck, can be recognised as one of the most favourable yet discovered in the Northern Territory. The radioactivity occurs in a quartzite breccia outcropping over a length of 1.5 miles and with a width of as much as several hundred feet. Geiger counter readings of 2 - 100 times background, occur frequently along the entire length of the outcrop, visible mineralization being present at three separate localities. The state of this mineralization, its associations and the geological settings are favourable to the possible occurrence of uranium mineralization at depth. Recommendations are made for further work, and problems in regional geology are discussed. The writer considers the sections of this report designated "Mineralization" and "Conclusions" to be the most important for a knowledge of the actual uranium occurrences. The remaining information is mainly geological, and, while highly pertinent, may not be of urgent interest to readers with a limited amount of time.

  • Report on the method and findings of the beach sands investigation in the area between ML180 and DC22, Broadbeach to North Burleigh. Estimates of the quantities and grades of heavy mineral concentrates, the quantities of overburden, and the quantities of each of the heavy minerals are tabulated.

  • The most important known deposits of what are commonly referred to as the beach sand minerals are situated along the most easterly part of the Australian coast. The geographical distribution, physiography, formation, origin, composition, and reserves of heavy minerals along the east coast are discussed in this report.

  • Notes on granite and structural features following an examination of the granite outcrop at Balladonia Station. A sketch plan of the outcrop is included this report.

  • This report is written primarily to present the determination of the permeability and porosity of a number of rocks and minerals, but it has also been considered advisable to give a brief description of the different kinds of apparatus designed and used in making the determinations. The materials on which the tests were carried out included a suite of specimens from No. 10 bore, Lakes Entrance, two specimens of sandstone from one of the bores at Roma, Queensland, and a number of Australian diatomites. The method of presentation adopted in this report is, firstly to describe the apparatuses used in making the determinations and the technique adopted in preparing the specimens for testing and secondly to discuss the results obtained for each set of specimens. In addition to the permeability and porosity tests already mentioned, a number of tests of compressive strength were made on wet and dry samples of glauconitic sandstone from Lakes Entrance.
