The CHILDARA 1:250 000 geological map covers part of the Precambrian Gawler Craton in north-western Eyre Peninsula, much of which is blanketed by Cainozoic and Mesozoic deposits. The oldest rocks are a complex assemblage of granitic gneisses and...

Wilkinson 1 stratigraphic well was drilled by the SA Department of Mines and Energy in mid-1978, about 250 km south-west of Coober Pedy, in the Tallaringa Trough. Here a thick section of Cambrian claystones, limestones and evaporites, at least 594 m...

Three stratigraphic wells (Ooldea no. 1, Reid no. 1, and Reid no. 1A) were drilled by the South Australian Department of Mines during 1976 in an area that includes margins of the Officer, Arckaringa and Eucla basins. Principal objectives were to test...

Isolated outcrops of Archaean to Early Proterozoic basement and Phanerozoic cover were visited by helicopter over BARTON and the western part of TARCOOLA in May 1988. This report summarises the technical and costing aspects of the survey, and...

MESA was contracted to find a groundwater supply for the Oak Valley Community. It was identified that the water's salinity was required to be less than 40,000 mg/l for desalination, and that the yield needed was 1 l/s. The investigation included a...

Two groups of samples from Eyre Peninsula have been analysed. The Elliston samples are correlative with the Polda Formation, probably in the latest Middle Jurassic. The younger Middle Eocene E04-1 sample indicates the presence of Pidinga Formation,...

The Oak Valley Community requires a more convenient water supply. If potable groundwater cannot be found then a supply suitable for purification must be found. Current requirements are a supply of 1 L/s of water of salinity not greater than 40 000...

A Transient Electromagnetic (TEM) survey was used to prospect for groundwater at three locations on the road between Yalata and Ooldea, on the thesis that water would be available in either deeper overburden or fractured basement. Overburden targets...

The palynofloras from eight drill cuttings samples taken from the depth interval 107-181 m KB in SADME Wilkinson 1 are described and dated. The youngest palynofloras are correlated with the Upper Nothofagidites asperus Zone, and are dated as latest...

Volcanic rocks from the Wirrulla region include dacites, rhyodacites and rhyolites. They comprise both magmatic and pyroclastic types, and are similar to the Gawler Range Volcanics. Sedimentary rocks from the same region include quartz sandstones...

Three drill cuttings samples were assigned a Late Eocene age.

A sample of carbonaceous mud was assigned a Late Eocene age.

Four horizons were mapped (top of basement, top of Permian, top of Cretaceous and Sea Floor). The Denman Basin is a 50 km wide, north-south trending depression in Early Palaeozoic - Precambrian bedrock, infilled with up to 400 metres of Permian...

The Duntroon Basin is located in the centre of the Southern Rift System between the Bight and the Otway Basins, west and SW of Kangaroo Island. It is limited to the north by the Proterozoic Gawler Craton. The formation of the basin is related to the...

Sediments analysed from VB06 and VB07 are correlative with an early phase of the Garford Formation, either in the Middle Miocene or the Early Miocene. The environment of deposition appears to have been fairly open marine, or at least an estuarine...

A sample examined from the CAR03-1 exploration drillhole is Late Eocene in age and correlative with the marginal marine upper part of the Pidinga Formation.

A replacement well for Tallowan 1 was drilled 100 metres east of Tallowan 2 to a depth of 72 metres. Production tests showed that the well was capable of producing 3.5 L/s with 6.4 metres of drawdown. Groundwater with a salinity of about 10 000 mg/L...

The Nundroo basement drilling project was proposed in February 1987 by SADME's Regional Geology Branch as the first phase of investigation of the little known rocks of the south-western Gawler Craton. Previous drilling in this area had been restricted...
