Cambrian sediments in the Arrowie Basin were deposited on a rifted continental margin. Four distinct depositional regimes, ranging from a western, tectonically stable shelf, through platform-ramp to eastern slope and trough-synclines, can be...

Surveys recently conducted in England, Ireland and Australia have shown that there are major spatial variations in the 'light' [molecular weight] hydrocarbon gas content of rocks which are closely related to the presence of underlying mineralisation....

Exploration of an area located 55-70 km east-southeast of Leigh Creek, where it was hoped that undiscovered Mississippi Valley - type lead-zinc mineralisation might exist within slightly folded Lower Cambrian strata, has consisted of 1:25,000 scale...

The availability of rainwater, and possible harvesting techniques and storage media are investigated. Reasonable amounts of rainfall occur, but falls are interspersed by long droughts. There are problems with silting up of dams, and with protecting...

Examination of an historically worked occurrence of stratiform base metal mineralisation near Balcanoona in the central Flinders Ranges, 50 miles east of Copley, has involved intensive geochemical sampling of abandoned mine adits, old dumps,...

Stream sediment sampling, conducted by Kennecott as follow-up to a 1966 regional surface geochemical reconnaissance programme looking for stratabound Mississippi Valley - type base metal deposits in the central Flinders Ranges, has located a small...

Evaluation of the base metal potential of minor historical copper workings within folded lower Cambrian strata, in an area located 25 km north of Quorn, failed to identify significant geochemical or geophysical evidence for shallowly buried...

A number of base metal occurrences in the northern Flinders Ranges, previously classified as syngenetic, diagenetic and epigenetic in nature, appear to have resulted from metalliferous brine-sediment interaction with autochthonous and allochthonous...

The reported presence of high geochemical zinc values in the Parachilna Formation rocks exposed there prompted Kennecott Explorations to include the Reaphook Hill outlier of Lower Cambrian sediments into its regional investigation of the stratiform...

Follow-up geological investigations to stream sediment and soil base metal anomalies earlier disclosed in the Ten Mile Creek area have concluded that the mineralised sources found for the two broadest lead and zinc anomalous zones do not indicate the...

An area located approximately 12 miles north of Quorn was re-issued to Kennecott over a reduced licence acreage, to permit further investigation of Cambrian Parachilna Formation and Wilkawillina Limestone strata which had shown anomalous copper, lead...

Reconnaissance geochemical exploration for possible economic stratiform copper deposits hosted by Adelaidean and Lower Cambrian sediments in an area of the northern Flinders Ranges located east of Blinman has consisted of aerial surveys,...

As part of a regional stratiform base metals exploration programme, the conduct of a helicopter-assisted stream sediment geochemical sampling survey (506 samples assayed) did not reveal any anomalies of interest.

Eleven traverses of rock chip samples were collected during a preliminary prospecting programme in SML 339 in the Reaphook Hill region of South Australia. While no obvious zinc or manganese deposits were located during investigations of the Lower...

Previously detected low-level geochemical anomalies for Cu, Pb and Zn were confirmed by follow-up stream sediment and soil sampling. Field inspections were made by helicopter of selected anomalous areas in the Upper Proterozoic and Lower Cambrian...

3414 geochemical reconnaissance stream sediment samples were taken over an area of 277 square miles for NFM during the period December 1969 - August 1971, and analysed for anomalous Cu/Pb/Zn in Sturtian-Marinoan to Lower Cambrian bedrock...

Exploration of an area located approximately 30 km south-east of Copley was aimed at finding possible Irish-type stratiform lead-zinc(-silver) sulphide mineralisation in localised sub-basin environments associated with growth faulting and brecciation....
