Prismatic pyramidal crystals from a vein in the Cretaceous Bulldog Shale are identified as possible celestite.

21 specimens of volcanics and felsic gneisses are heterogeneous in both original lithology and the extent of metamorphic and metasomatic alteration. Strong granitic metasomatism may indicate concealed granitoid plutons. Continuation of andesitic...

Reserves of 12.1 million tonnes of dolomite are indicated, but are conditional upon removal of 2.2 million tonnes of waste dumps and of 5.8 million tonnes of phyllite.

2 small vertical lodes which cross cut dolomite, contain inferred reserves of 1100 tonnes of oil drilling grade barite. Selective mining should also yield industrial grade, if deeper barite is less iron stained. Neither lode has been worked.

Includes surface and subsurface stratigraphic data, and a geological map at 1:500 000 scale. 18 bores were re-logged.

The Electricity Trust of South Australia requires a source of high grade limestone or dolomite to be used in the planned industrial firing process for brown coal from the Wakefield coal deposit. A SADME survey of available literature, supplemented by...

Petrology of 174 rocks indicate that 5 deformation phases (D1 - D5) are present within this dominantly schistose domain. Describes many samples which contain gneissosity, schistosity or crenulation.

South Australia has been a traditional source of non metallic minerals. Those minerals currently being mined that offer scope for expansion is – Barite – In pigments, drilling muds, the manufacture of barium chemicals and for medical purposes...

Describes rocks from 3 areas formerly mapped as Flinders Group. Granites in each area are distinctively different, but metasediments are similar.

Byilkaoora 1, a stratigraphic well drilled in the northeastern part of the Officer Basin in South Australia, intersected aeolian and fluvial sandstones and mudstones overlying 224 m of fine-grained, dolomitic, calcareous and argillaceous sediments...

Stratigraphic sections were measured through the Callanna Beds and lower Burra Group, by tape and air photo enlargement, at the following localities: (1) north-east of Kingston Dam, (2) south-east of Dome Hill and (3) west of Callanna Homestead. At...

A detailed description and interpretation of the carbonate lithologies present in drill cores recovered from two recently completed SADME stratigraphic wells have revealed that the Observatory Hill Beds in the Marla area were deposited in a shallow...

EML 3554, 9 km NW of Tumby Bay, contains 3 separate marble outcrops, each 40 metres wide, of similar mineralogy, which are isoclinally-folded Katunga Dolomite of the Hutchison Group of Lower Proterozoic age. The marble quarries where mapped, surveyed...

A visit during September 1978 to two United Kingdom water authorities, Wessex and Yorkshire, proved very worthwhile. Aspects of investigational techniques, waste disposal, and groundwater abstraction effects on river flow were examined....
