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.

An examination was made of a wolfram vein seven miles north of Broken Hill, on July 8th, 1943. This report contains brief notes on the nature of the vein and the mineral specimens examined.

The presence of laterite described as high-silica bauxite at Mt. Roe on Cobourg Peninsula had been reported early in this century by H.Y.L. Brown, who submitted a specimen for analysis. In the absence of information about the mineralogical composition of the rock the chemical analysis alone affords a very incomplete description of the material. It was considered that the rock might be somewhat similar to the commercially valuable high-silica bauxite which occurs in the Netherlands East Indies and Malaya. At the request of the Australian Aluminium Production Commission the writer was instructed to examine the area in the vicinity of Mounts Roe and Bedwell, and to sample and report on any accessible bodies of apparently aluminous laterite. The locality, topography, and general geology of the area are briefly described. Accounts of the laterite occurrence at Mounts Roe, Bedwell, Kura, and Victoria are given. The mineralogical character of the laterite is described.

The Northern Territory is an integral part of the great Australian Pre-Cambrian shield which underlies almost the whole of Western Australia and the Northern Territory, much of South Australia and portions of New South Wales and Queensland. In most parts of the Continent, Pre-Cambrian rocks were welded into a stable shield before the end of Pre-Cambrian time, and in the Northern Territory itself the structural framework was established, and most of the mineral deposits introduced by an orogeny which terminated geosynclinal sedimentation about the end of the Lower Proterozoic. This discussion of the structure of the Territory in relation to mineralization is mainly concerned with Pre-Cambrian, and in particular with Lower Proterozoic rocks. Only a broad outline of the subject is given here.

For trade purposes four types of asbetos may be recognised - Amphibole, Blue Asbestos, White Asbestos, and Amosite. This report contains notes on the possibility of substituting these types of locally produced asbestos for imported chrysotile.

The mineral resources and mining industry of the Mandated Territory of New Guinea are the subject of this report. Mining operations, production, and geological conditions are discussed. Tables showing the estimated gold and silver production figures for the period 1926-41 are appended.

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.

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.
