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.

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).

Australia wide mineralogical maps have recently been generated and released by CSIRO and Geoscience Australia using the 14 band satellite-borne ASTER imaging sensors. Seventeen map products related to surface composition have been produced for the geoscience community. Band parameters were developed based on spectral absorption features representing either abundance of mineral groups, specific minerals and their chemistry, vegetation cover or regolith related characteristics. A detailed study was undertaken, investigating the geoscience exploration capabilities of these newly released map products, individually, and integrated with airborne geophysics and digital elevation models over the Mt Fitton test site in northern Flinders Ranges, South Australia. This site includes the Mt Fitton talc deposits, gold prospects, and areas of hydrothermal activity and metasomatism.

An area of about 190 acres lying within the boundaries of Allotment 26D, Budgeree, County of Buln Buln was taken up for prospecting purposes on 21st May, 1947. The topography, general geology of the area, and the occurrence, volume and grade of the bauxite bodies, are discussed in this report. Three accompanying plans are included.

During the last three years much work has been done on laterites in Northern Australia by geologists of the Bureau and in particular those attached to the North Australian Regional Survey. The co-operation of soils officers and geologists in this survey has led to a better understanding of the significance of laterites and of the zones within the profiles. Since several parties from the Bureau are now working in Northern Australia it seemed opportune to discuss the nomenclature of laterites and to suggest terms and definitions so that laterites can be described and mapped in the same way by the several field parties. With this object in view geologists from the Bureau and officers from the North Australian Regional Survey discussed the matter and the following terminology and definitions are circulated now for criticism within the Bureau.

Boring commenced in the Broadbeach area on an East-West line 500 feet south of the northern boundary of DC22. Subsequent boring was carried out along lines 1300 feet, 2100 feet, 2900 feet, 4500 feet, 6125 feet, 7740 feet, 9300 feet, and 10900 feet south of the northern boundary of DC22. The results of the beach sands investigation are presented here. Estimates of the tonnages of heavy-mineral concentrates, the average grades of the heavy-mineral bearing sands and the average thickness of overburden, are tabulated. The complete set of data, from which these figures have been calculated, is attached as an appendix to the report.

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.

These notes are compiled as a result of conversations with Government officials and mining engineers in Noumea on 4-6th July, 1951. Figures are given for the production, reserves, and exports of Nickel, Chromite, Manganese, Cobalt, Iron, and other miscellaneous minerals. Most of the figures quoted herein have been compiled from records collected by the Australian Consul.

This report outlines the headings under which mineral statistics might be collected, and the information that is required from metal and mineral producers. Attached are lists of metals and mineral products under the appropriate classes.
