The Adelaide Geosyncline is a deeply subsident Neoproterozoic to Middle Cambrian basin complex in South Australia with a record of at least five major successive rift cycles. Each rift system has its own locus and orientation. Although the rift...

This report is on the Otway Basin, South Australian sector. It covers the structural and tectonic history and the methodology of the seismic interpretation. Contour maps enclosed are time and depth structures of the Sherbrook Group, Eumeralla...

The Gawler Range Volcanics outcrop extensively across the central part of the Gawler Craton. They form a Mesoproterozoic volcanic complex made up of many ash flows, ignimbrites, lava flows and air-fall tuffs. This report is a compilation of...

Wollastonite is a calcium silicate mineral of high temperature metamorphic or igneous origins, which lately has been found to have an increasing range of industrial applications. Its main producing country is China. At Ethiudna, in South Australia's...

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...

This 4-day field trip demonstrates :- Willyama Complex (basement) stratigraphy,- deformation and metamorphic style of the Olarian, Orogeny (including possible recumbent folds), - large blocks of granite and migmatite, up to 800 metres, long, within...

The Cambro-Ordovician Black Hill Norite inlier protrudes through Tertiary marine sediments of the Murray Basin about 85 km east of Adelaide. Available evidence suggests that the complex may be a layered mafic-ultramafic intrusive suite with potential...

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...

During the period March to June 1990, 9 stratigraphic rotary mud/diamond cored holes with a total penetration of 3056 m, including 433.25 m of NQ or HQ cored diamond tails, were drilled by SADME in three cases and by its contractor Rockdril for the...

Specimens from the south-west of the province are similar to those in the rest of the province, except that an alkali amphibole with anomalous optical properties occurs, both in lamproite blocks from the diatreme, and in an outcrop near a crocidolite...

The metamorphic rocks to be examined on the field excursion have been assigned to the Tapanappa Formation (Early Cambrian Kanmantoo Group), a generally monotonous sequence of greywackes with narrow siltstone partings. This formation hosts most...

Fully HQ/NQ cored SADME stratigraphic drillhole Mount Rufus 1 was sited on the western margin of the Karinya Syncline to investigate the nature of the Adelaidean - Early Cambrian Normanville Group contact, and the mineral potential of the area. It...

The Red Creek section is proposed as a reference section for the Heatherdale Shale, Truro Volcanics, Carrickalinga Head Formation and Backstairs Passage Formation for the Karinya Syncline area of the Kanmantoo Trough. To date, 934 metres have been...

Two major belts of anomalous gravity and magnetic intensity are distinguished at the SW margin of the Murray Basin. The main belt is about 420 km long and is arcuate in broad outline. In detail it appears to be controlled by three major linear...

Drilling and sampling of basement rocks underlying the south-western Murray Basin, newly performed by CSR Ltd and SADME, have revealed that a hitherto unknown igneous domain exists there. The most abundant rocks are altered and soda-enriched basaltic...

Sedimentation in the Great Australian Bight (GAB) has occurred in a variety of settings from the initial intra-cratonic rift to the modern carbonate shelf. An extensive palaeodrainage system, remnants of which are still preserved, supplied clastic...

Company exploration within the CURNAMONA 1:250 000 sheet area was reviewed by the study of data incorporated in the open file reports on 42 Special Mining Leases, 80 Exploration Licences and one group of Mining Leases dating from 1961. This data...

The Officer Basin probably formed when the Gawler Craton collided westerly with the Yilgarn Craton during 1300-1000 Ma; the collision-faulted belt of the Fraser-Musgrave Orogen might form the basement of the Munyarai Trough in the eastern part of the...
