SA Gravity Survey 1998A7 (P199857), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 SA Gravity Survey 1998A7 (P199857) contains a total of 138 point data values acquired at a spacing of 100 metres. The data is located in SA and were acquired in 1998, under project No. 199857 for None.

Curnamona 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 Curnamona total count grid geodetic has a cell size of 0.00083 degrees (approximately 86m) and shows the terrestrial dose rate of the Curnamona, SA, Broken Hill Exploration Initiative, 1995. The data used to produce this grid was acquired in 1995 by the SA Government, and consisted of 62542 line-kilometres of data at a line spacing between 100m and 400m, and 60m terrain clearance.

L004 Northwest Cape, Carnarvon Basin Seismic survey, WA, 1951

The seismic survey made by the Geophysical Section of the Bureau of Mineral Resources to assist in the search for oil in the Carnarvon (North-West) Basin of Western Australia. The seismic field work in the Carnarvon Basin was confined to one field season, i.e., from April to December 1951, and consisted of surveys on the Capa Range and Giralia Anticlines. Both refraction and reflection methods were used. The purpose of the seismic work was to determine if the structures at surface extended to depth and thus establish if a suitable site for a deep exploration drill hole exist.
The seismic work has shown that seismic methods are applicable in the investigation of possible oil-bearing struotures in the Carnarvon Basin. It is clear from the results obtained on the Giralia Anticline, that investigation with a view to tile selection ot deep drilling sites cannot be carried out thoroughly
without seismic surveys of selected areas.

This GSV Ballarat Vic pot tho ura totg 4band radiometric grid geodetic is an airborne-derived radiometric Potassium, Thorium and Uranium data over a sun shaded total count radiometric data for the Ballarat, Vic, 1986 (GSV0312). 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 GSV Ballarat Vic pot tho ura totg 4band radiometric grid geodetic has a cell size of 0.0005 degrees (approximately 49m). The data used to produce this grid was acquired in 1986 by the VIC Government, and consisted of 11552 line-kilometres of data at 200m line spacing and 70m 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.

NETGOLD - Weymouth-Cape Portland, TAS, 1993 (P781), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field 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. The data 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.
 These line dataset from the NETGOLD - Weymouth-Cape Portland, TAS, 1993 survey were acquired in 1993 by the TAS Government, and consisted of 4309 line-kilometres of data at 400m line spacing and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

AUSGeoid98 v.1.0 data files: (sf49-05)

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.

Alice Springs International Map of the World (IMW) 1:1 000 000 topographic map

The International Map of the World (IMW) series is no longer maintained, and printed copies of this map are no longer available. The Australian portion of the series consists of 49 maps. They were produced to an international specification using the R502 series at 1:250,000 scale as source material. Production commenced in 1926 and was completed in 1978. The maps were revised from time to time and the last reprint was undertaken in 2003. Each standard map sheet covers 4 degrees of latitude by 6 degrees of longitude and was produced using a Lambert Conformal Conic projection with 2 standard parallels. The series has recently been superseded by the 1:1 000 000 topographic map general reference.

The age and genesis of the Nifty copper deposit: back to the future

A Nd-Sm isochron from apatite in apatite-chalcopyrite veins mostly in the footwall to the Nifty
deposit indicates an age of 791 ± 43 Ma. As this apatite is paragenetically associated with
chalcopyrite in the veins and in the ore zone, this age is interpreted as the best estimate for the timing
of mineralisation at the Nifty deposit. Consideration of the temporal evolution of Nd values
precludes deposition of the apatite significantly younger than 800 Ma. The U-Pb systematics of the
apatite have been disturbed, resulting mostly in highly scattered arrays that do not have geologic
significance.
Observations on primary fluid inclusions in quartz from the apatite veins suggest low temperature,
relatively high salinity brines. These observations, the geochronological constraints and large ranges
in sulphur isotope values suggest that the Nifty deposit formed early, possibly diagenetically, from
low temperature, relatively oxidised fluids. This inference is consistent with the original model for
the Nifty deposit (Haynes et al., 1993) though less consistent with the tectonic model proposed by
Anderson et al. (2001).
Structural modelling assuming that mineralisation is early shows that the north trend of ore shoots
reported previously on the northeastern limb of the Nifty Anticline is consistent with control by
antithetic normal faults developed during basin formation. If this model is correct, these antithetic
normal faults would trend west-southwest on the southwestern limb of the Nifty Anticline. This
trend has not been adequately drill-tested, and provides scope for additional near-mine exploration
on the southwestern limb of the Nifty Anticline.
