GSNSW Exploration NSW Area D Surat Basin uranium grid geodetic

This GSNSW Exploration NSW Area D Surat Basin uranium grid geodetic is an airborne-derived radiometric uranium window countrate grid for the NSW DMR, Discovery 2000,1994-95, Area D, Surat Basin survey. 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 uranium (K), uranium (U) and uranium (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.
This GSNSW Exploration NSW Area D Surat Basin uranium grid geodetic has a cell size of 0.00072 degrees (approximately 75m). The data are in units of counts per second (or cps). The data used to produce this grid was acquired in 1995 by the NSW Government, and consisted of 117000 line-kilometres of data at 400m line spacing and 80m terrain clearance.

Resource potential of the Proterozoic−Paleozoic Carrara depocentre, South Nicholson region, Australia

A comprehensive geochemical program was carried out on rock samples collected in the NDI Carrara 1 drill hole, the first stratigraphic test of the newly discovered Carrara Sub-basin located in the South Nicholson region of northern Australia. The drill hole recovered continuous core from 284 m to total depth at 1750 m and intersected approximately 1120 m of Proterozoic sedimentary rocks, unconformably overlain by 630 m of Cambrian Georgina Basin carbonate-rich rocks. Total organic carbon (TOC) contents from Rock-Eval pyrolysis highlight the potential for several thick black shales to be a source of petroleum for conventional and unconventional plays. Cambrian rocks contain an organic-rich section with TOC contents of up to 4.7 wt.% and excellent oil-generating potential. The Proterozoic section is overmature for oil generation but mature for gas generation, with potential for generating gas in carbonaceous mudstones showing TOC contents up to 5.5 wt.% between 680 and 725 m depth. A sustained release of methane (up to 2%) recorded during drilling from 1150 to 1500 m suggests potential for an unconventional gas system in the Proterozoic rocks from 950 to 1415 m depth, which exhibit favourable organic richness and thermal maturity. The Proterozoic rocks, which are comparable in age to the sediment-hosted deposits of the Century Mine, contain local occurrences of lead, zinc and copper sulfide minerals providing hints of mineralisation. The combined geochemical results offer the promise of a potential new resource province in northern Australia.

AUSGeoid98 v.1.0 data files:  (sd55-15)

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.

Correlation between lithospheric resistivity and gold deposits in southeast Australia: statistical and geological significance

Gold deposits form in a range of geodynamic settings and styles of deposition, associated with specific characteristics in fluid source and chemistry. These differences may lead to differences in the minerals that are deposited in the ascent pathway, and thus alter the physical properties that can be measured at different levels in the lithosphere. Models derived from magnetotelluric data are sensitive to lithospheric resistivity variations and have been increasingly applied to mineral exploration, with evidence emerging for a spatial association between many mineral deposits and lower crustal conductors.
Southeastern Australia has estimated resource of ~5000 t gold contained within a variety of deposit styles. A resistivity model of this region was recently published from Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) data under a collaborative project between Geoscience Australia, the Geological Survey of New South Wales, and the Geological Survey of Victoria. This showed a strong spatial correlation between lower crustal conductors and gold deposits. In this presentation we examine the statistical and geological significance of this correlation for different deposit styles. We demonstrate that there are clear differences in the resistivity expression between different styles of gold deposition. The variability may reflect differences in the fluid source chemistry and geodynamic setting of the deposits, and will have important implications for the exploration of these resources.

The R502 series of maps has been replaced by the National Topographic Map Series (NTMS). The R502 series consists of 542 map sheets and covers Australia at a scale of 1:250,000. It was compiled from aerial photography, but only about one quarter of the series was contoured. The standard sheet size is 1 degree of latitude by 1.5 degrees of longitude. Transverse Mercator map projection and Clark 1858 datum were used. Coverage of the country was completed in 1968.

Summary Of Data And Results Bass Basin, Tasmania Esso Bass No. 1 And No. 2 Wells Of Esso Exploration And Production Australia Inc. (Formerly Esso Exploration  Australia Inc.)

Esso Bass No. 1 Well was drilled by Global Marine Australasia pty Ltd. using "Glomar Ill", for Esso Exploration Australia Inc., in Tasmanian waters of the offshore Bass Basin. about 88 miles east of King Island. The well was spudded on 21 July 1965, reached total depth of 7717 feet on 8 September. and was plugged and abandoned on 14 September 1965. A full programme of logging and coring was undertaken.
The Bass Basin, lying entirely between Victoria and Tasmania, covers an area of approximately 25.000 square miles. From magnetic data. it was inferred to contain a thick sedimentary section; from seismic data and extrapolated regional geology. The sedimentary section was thought to include Tertiary sediments favourable for petroleum generation and accumulation. The well was thus designed to gain stratigraphic information on the Tertiary and upper part of the Mesozoic sedimentary section in the
north central Bass Basin. and. in particular. to test the petroleum potential of a postulated reef-type anomaly in the Miocene section.

Towards 3D maps of alteration under cover: Regional constrained 3D inversion of potential field data from the Olympic Cu-Au province, South Australia

Regional-scale constrained potential field inversions can be used to map rock types, alteration, and structure. This is particularly valuable when basement is obscured by younger cover. The methods outlined in this study have been applied to a 150 km Ã— 150 km region around the giant Olympic Dam copper-uranium-gold deposit, where abundant haematite, sulphide, and magnetite alteration produce strong potential field signatures despite thick cover. The results are used to develop the first 3D map of magnetite and haematite/sulphide alteration for the Olympic Cu-Au province, and show that the alteration around known Cu-Au mineral occurrences can be detected using coarse regional-scale inversions. The provision of a reference model in the inversion formulation permits geological observations to be introduced into the inversion process to guide the inversion towards more geologically reasonable results. This allows hypotheses regarding 3D geological architecture to be rigorously tested for compatibility with potential field data. An iterative procedure of inversion followed by updating the reference model allows 3D maps of alteration and structure that are consistent with both the known geology and observed potential field data.
