A survey of phosphate deposits in the south-west Pacific and Australian Waters

In 1955 a programme of search for phosphate, to supplement the diminishing reserves of Ocean, Nauru, and Christmas Islands, was agreed upon by the Australian and New Zealand Governments. This Bulletin describes the search of islands of the South-West Pacific and Australian waters by the Bureau of Mineral Resources. Islands off the northern coast of Australia were investigated in 1957, the British Solomon Islands and islands off Papua and New Guinea in 1958, and Fiji, Tonga, and the Gilbert and Ellice Islands in 1959. The deposits of Bellona Island, B.S.I.P., are the only ones investigated by the survey that could be exploited and exported ; they contain about 500,000 tons of grade 30-3 percent P205 and 4,500,000 tons of grade 22-3 percent P205 . Other, smaller, deposits were found in: the Purdy Islands, Sae, and Manu (New Guinea); Tamana, Vaitupu, Abemama, Nukufetau, Tabiteuea , and Nui, in the Gilbert and Ellice Islands ; Vanua Vatu , Ogea Driki, and Tuvuca in Fiji ; and islands in the Ashmore Reef, Northern Territory . Many other islands contained traces of phosphate. The origin and uses of various types of phosphate deposit are reviewed.

GSNSW Exploration NSW Area I Albury total count grid geodetic

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This GSNSW Exploration NSW Area I Albury total count grid geodetic has a cell size of 0.00049 degrees (approximately 50m) and shows the terrestrial dose rate of the NSW DMR, Discovery 2000, 1994-95, AREA I, Albury. The data used to produce this grid was acquired in 1996 by the NSW Government, and consisted of 35041 line-kilometres of data at 250m line spacing and 60m terrain clearance.

GSQ Eulo 2 borehole completion record: Southern Thomson Project

The Neoproterozoic to Paleozoic Thomson Orogen is a major component of the Tasmanides of
eastern Australia that extends through large portions of central and southwest Queensland and
northwest New South Wales. Much of the Thomson Orogen is buried under younger
sedimentary basins (some up to several kilometres thick) and regolith cover, making it one of the most
poorly understood elements of Australia’s geology. As a result, the mineral potential of the region is
also poorly defined.
The Southern Thomson Project (the Project) is a collaborative investigation between the
Commonwealth of Australia (Geoscience Australia – GA) and its partners the State of New South
Wales (Department of Trade and Investment, Geological Survey of New South Wales – GSNSW) and
the State of Queensland (Department of Natural Resources and Mines, Geological Survey of
Queensland – GSQ).
The Project aims to better understand the geological character and mineral potential of the southern
Thomson Orogen region, focusing on the border between New South Wales and Queensland, by
acquiring and interpreting multi-disciplinary geophysical, geochemical and geological data. The
primary intended impact of this work is to provide the mineral exploration industry with pre-competitive
data and knowledge that reduces risk and encourages mineral exploration in the region.

Total Magnetic Intensity (TMI) greyscale Image of Australia 2019 with Variable Reduction to Pole (VRTP)

This image is a greyscale image of the Total Magnetic Intensity (TMI) Anomaly Image of Australia with Variable Reduction to Pole (VRTP).
Total magnetic intensity (TMI) data measures variations in the intensity of the Earth magnetic filed caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. 
A variable reduction to Pole is aimed at locating magnetic anomalies exactly above their source bodies and without any distortion. The  image is created from the 2019 variable reduction to Pole of the TMI grid with a grid cell size of ~3 seconds of arc (approximately 80 m). This image only includes airborne-derived TMI data for onshore and near-offshore continental areas.
The image provides a better interpretation of the magnetic data by giving an accurate location of magnetic source bodies.

AUSGeoid98 v.1.0 data files: Port Augusta (si53-04)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

The Paterson 3D VRML model

Note: 3D VRML model is no longer supported
The Paterson 3D VRML model of the Cottesloe Syncline region in the northwest Paterson Orogen was created using 3D GeoModeller. 3D GeoModeller is an emerging technology that constructs 3D volumetric models based on a range of geological information. The principal benefit of 3D GeoModeller is that it provides geoscientists with a rapid tool for testing multiple working hypotheses. The models were built by members of the Paterson Project, as well as model building specialists within Geoscience Australia as a two-fold exercise. The primary purpose was to test the capabilities of 3D GeoModeller, while the secondary purpose was to evaluate the project's understanding of the 3D geology of the study area. 
Two 3D models of the Cottesloe Syncline were constructed, the first one utilising geological observations only from the geological map, and the other including the outcrop observations as well as an interpreted solid geology of the area. The resultant Cottesloe Syncline models, including two dimensional maps and images, were exported from 3D GeoModeller and transformed into Virtual Reality Modelling Language (VRML), enabling a wide audience to view the model using readily available software. For more information on how the Paterson Project used 3D GeoModeller to construct the Cottesloe Syncline model, see Constructing geologically-constrained 3D models using 3D GeoModeller.
Geographic extent
The Paterson Orogen is located in Western Australia and is situated between the Pilbara Craton to the southwest and the Canning Basin to the northeast. The Cottesloe Syncline 3D model covers an area of 30 x 35 km and is situated in the northwest of the Paterson Orogen.
Content
The Paterson 3D model and associated data sets consist of: a scanned image of the central portion of the Broadhurst 1:100 000 geological map sheet; an image of the Digital Elevation Model; input geological observations from the geological map; additional observations based on an interpreted solid geology; 3D surfaces of the various geological units based on the geological observations; and 3D surfaces based on the geological observations and the interpreted solid geology. 
Software required
Geoscience Australia's X3D and older VRML models require the free plugin BS Contact and work best with the web browser Internet Explorer version 6 or higher.
Size
Approximately 7.5MB Startup download is 69KB - the remaining datasets download when selected.

This GSV Horsham VIMP Vic pot tho ura totg 4band radiometric grid geodetic has a cell size of 0.0005 degrees (approximately 50m). The data used to produce this grid was acquired in 1994 by the VIC Government, and consisted of 73755 line-kilometres of data at a line spacing between 200m and 400m, and 80m terrain clearance.  The grid was produced by applying the colours red to the Potassium ground concentration, green to the Thorium concentration and blue to the Uranium concentration. The colours were clipped to a 99% linear scale. These colours were transparent over a shaded Total Count. This clipping will necessarily introduce some artefacts into the ratio grids in areas of very low radioelement concentrations. The 3-band image was superposed on the sun shaded TC grid of the same survey to produce the final image.
