Of the well's total depth of 1495 metres, the top 433 metres are fossiliferous, for which this report outlines the stratigraphy as determined from selected drill cores and cuttings. The biostratigraphy of the sequence studied in Mallabie 1 proves the...

The molluscan faunas of the Upper Eocene Wilson Bluff Limestone and Miocene Abrakurrie and Nullarbor Limestones are identified and figured. The brachiopods of the Wilson Bluff and Abrakurrie Limestones are identified.

Ballast of moderate quality is won from an indurated fragmental limestone capping on the Nullarbor Plain. The assumption that ballast is available all over the Plain is valid, but the thickness of the cap rock zone varies from place to place. There is...

Samples obtained from five quarry faces and one outcrop on the Transcontinental Railway are classified into 6 types of material, probably representing at least four generations ranging from Nullarbor Limestone to superficial material from the surface.

Preliminary maps were compiled by photointerpretation with limited geological ground control. Some topographic features and photo - lineaments are considered structurally significant and may reflect faults with NE - ENE and NW orientations. The...

Two limestone samples from an area 80-105 km north of Cook, towards the northern margin of the Eucla Basin in South Australia, are identified as Nullarbor Limestone of ?late Lower and Middle Miocene age. The former, coarsely calcarenitic, has...

Outcrop and subsurface samples taken from various sources, that represent all the Cainozoic marine formations of the eastern Eucla Basin, have been studied. The current stratigraphic knowledge of these formations in SA is summarised. A marine...

This report deals with the stratigraphy and economic geology of an area on the eastern margin of the Eucla Basin and the western margin of the Gawler Block. The area is centred upon the FOWLER 1:250 000 map area. The stratigraphic section of the...

This report summarizes results of drilling to obtain water supplies for construction of the Eyre Highway, to the beginning of June, 1973. Drilling problems in the limestone have been encountered. Production from open trenches has been moderately...

Seismic experiments were carried out in early 1974 over gravity and magnetic anomalies in the northern Eucla Basin in South Australia to determine whether results could be obtained using a directed line source in an area where dense, cavernous...

Drilling and pump testing of selected bores along the Eyre Highway between Penong and Eucla was completed in August, 1973. Water supplies have now been established all along the route. This report contains final results of the survey. Geology and...

An area situated on the eastern margin of the Nullarbor Plain has been explored for possible economic sedimentary uranium deposits that may have formed in Tertiary strata underlying the Nullarbor Limestone. The target porous sediments are those...

An area centred approximately 200 km north-west of Ceduna was taken up initially to explore for possible buried nickel mineralisation, and subsequently was farmed out to companies interested in assessing its base/precious metal and sedimentary uranium...
