Over 12 000 tonnes of barite have been produced, 11 km SSW of Oraparinna Barite Mine in Class B Environmental area. 4000 tonnes remain in blocks, fragmented sheets and shallow dipping veins + 10 000 tonnes if deepened, and 2500 tonnes inferred east of...

The Musgrave Block is a large area of Precambrian crystalline basement situated in the north-western corner of South Australia, and extending into Western Australia and the Northern Territory. Geological mapping has revealed large areas of granulite...

SADME and exploration companies have carried out magnetic, gravity, and seismic surveys in the basin since 1961. Areas of significant sedimentary thicknesses have been found in troughs which contain rocks of Permian, Devonian, and Cambrian age below...

Detailed gravity survey indicates a Tertiary palaeochannel, 1 km wide, incised into Cambrian - Precambrian bedrock. This depression is difficult to correlate with bedrock depressions in the Port Gawler area. The palaeochannel may be of interest for...

A proposed new group of 2000-tonne silos to be constructed alongside a railway line near Millicent will have their footings in limestone. 146 gravity stations on a 5 m grid have delineated a 10 m wide strip of possibly cavernous rock at depths of less...

A gravity survey was conducted along streets around Scotch College to establish the depth to basement below the college grounds. This information was required to help site a water bore. A major fault runs diagonally across the college grounds. The...

This outline was compiled from available seismic and drilling data. Renewed exploration activity has shown the need to upgrade information relating to the Permian and the ?Cambrian sub-basins beneath. 2 seismic programmes, to clarify the structural...

Model has been constructed from magnetic, gravity and seismic data from EL 370 (Aquitaine and Delhi), of a shallow horst of granitoid basement in the southeast of Yadlamalka 1:50 000 area, and, under the lake, a basin, up to 4 500 metres of dense...

An intensive search for copper and base metals was carried out 1965 - 1972 by both companies and SADM, with no discoveries being made. Geophysical and geochemical methods were used extensively.

A gravity survey was carried out in the Mallala-Balaklava area located about 56 km north of Adelaide as shown on Fig. 1. Twelve days were spent in fieldwork. Reduction and interpretation of results occupied a further fourteen days.

The Stuart Shelf region is a stable platform of Carpentarian and older crystallisation basement which is overlain by flat-lying Adelaidean and Cambrian sediments. It extends eastward from the exposed crystalline Gawler Block area to the mobile...

Tonnages and gold content of tailings and slimes stockpiled at the Government Stamp Battery at Peterborough were calculated from hand auger drilling and mining return records. The amount of recoverable gold was determined by mineralogical and...

Detailed gravity survey was made to locate boundaries of coal-bearing areas, since coal found near Lock appears to be associated with Bouguer gravity minima in the basin. Additional observations and drilling of possible targets will be required to...

From 1973 - 1978, 2000 tonnes of barite were produced from Bairstow Lodes and 16 tonnes in 1966 from nearby Tom Hill Lode. The lodes were mapped, surveyed and sampled. The steep barite lodes have formed in a fractured zone which cuts the enclosing...

Gravity results indicate the position of a major fracture accompanied by minor en-echelon fractures. Relative throws have been computer modelled corresponding to drill hole and previous basement depth data. Resistivity results produced pseudo...

This report is a chronological record of geophysical surveys carried out in the eastern and western portions of the Officer Basin region within South Australia, from 1954 to 1978. It contains references to all known documents relating to the...

Seven gravity traverses were established along roads immediately west of the Eden-Burnside fault zone in the Magill, Burnside and Parkside districts. By relating the observed gravity minima to increased thicknesses of Quaternary sediments (clays and...

Exploration for a suitable underground gas storage target in the Northern Adelaide Plains was initiated in 1964. Prior to the present investigation, four other areas have been examined and rejected as target areas, mainly due to the shallow depth of...
