In a search for East Alligator River - type metamorphic uranium deposits, a review of previous geophysical data plus the conduct of ground and airborne radiometric surveys disclosed a number of anomalies in an area on central Eyre Peninsula extending...

North Ltd's Barton Project commenced in 1990 across a number of licences progressively taken out over the western Gawler Craton, which eventually came to include EL 1865. Initial exploration for heavy mineral sand in the Barton-Ooldea area, 100-200...

WMC's Stuart Shelf exploration activities from 1975 to 1985 have sought mainly Olympic Dam style mineralisation (copper - uranium - precious metals in haematitic breccia host rocks), with lesser emphasis directed at: possible distal analogues of the...

The Gawler Range Volcanics show only trace amounts of molybdenum, silver and tin. In the Tarcoola area, significant amounts of tin in altered granite near Warna Rock Hole and high silver and lead values at Pinding Rocks are worthy of follow up....

Middle Proterozoic red granite is quarried near Calca, 35 km SE of Streaky Bay on western Eyre Peninsula. It is ideally suited as dimension and monumental stone, being fresh, uniform in texture and colour, and comparatively free of defects. It is...

Examines numerous outcrops illustrating the geological and tectonic evolution of the region. This excursion is based on the EPIC tour of the Geological Society of Australia 8th Australian Geological Convention excursion series in February 1986. This...

By 30 June, 1980, mapping of about two-thirds of YARDEA had been completed. Work to date has been concentrated mainly on the Gawler Range Volcanics which extend over most of the northern two-thirds of YARDEA. About 80% of the volcanics have been...

Brief summary progress report.

Volcanism associated with the Middle Proterozoic Gawler Range acid volcano-plutonic province was initiated in the Kokatha area by the construction on Archaean basement of a large stratovolcano composed mainly of tholeiitic basalt and potassic basaltic...

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...

This excursion guide is a refinement of a 6-day excursion led by Parker, Fanning and Flint in 1980 at the height of economic interest in the basement geology of the Gawler Craton. The interest in those days was for Alligator River - style uranium...

Outcrops of Proterozoic rocks consist of a complex suite of comagmatic intrusives which exhibit a variable degree of deformation and are correlated with the Early Proterozoic Lincoln Complex. On southern Saint Peter Island, felsic volcanics,...

Extensive field geological mapping, augmented by petrological and geochemical studies, reinterpretation of company drilling and water-bore logs and a nine-hole drilling programme has detailed the geology of the KINGOONYA area. The stratigraphy spans...

This 5-day field excursion was mounted by the GSSA to inform government and industry participants about significant newly identified geological features within the central Gawler Craton which are the subjects of ongoing study. The itinerary chosen...

Reconnaissance sampling of Mesoproterozoic Hiltaba Suite granite on northern Eyre Peninsula, to identify all potentially quarryable granite varieties, was carried out by MESA during 1996/97. A total of 157 outcrops were inspected and 99 samples...

Archaean and Early and Middle Proterozoic rocks of the north-western Gawler Craton have features which suggest good prospectivity for base metals, precious metals and other commodities. However, outcrop is poor and there has been relatively little...

This report summarizes information on 10 South Australian mineral deposits with individual aggregate gold resources and/or historic production of 1 tonne or more. By far the largest is the Olympic Dam Cu-U-Au-Ag deposit, with a measured and indicated...

Silica Beach, 45 km SSE of Streaky Bay, is the source of a well sorted and well rounded, very coarse-grained sand, extracted in limited quantities since 1970 for filtration and other uses at Whyalla Steelworks. Sand and gravel are derived locally from...

Volcano-plutonic rocks of the Nuyts Archipelago represent a discrete phase of felsic magmatism at about 1630 Ma. Associated with the Nuyts Volcanics are grey alkali granites, leucogranites and leucoporphyries - here defined as the Saint Francis...
