A regional geological interpretation of newly-acquired magnetic data for the majority of the Musgrave Block (central Australia) has been compiled at 1:250 000 scale. This report outlines the methodology and results of interpretation. Highlights of...

The Mingary 1:100 000 map area in the north-east of the state covers part of the Curnamona Province. Five suites of basic intrusives have been identified in the area. The most widespread is a series of amphibole-bearing sills which, having an...

The enigmatic Radium Ridge Breccias (Drexel and Major, 1987) of the Mount Painter Inlier in the northern Flinders Ranges have fascinated geoscientists since the first major attempt to understand the geology during and immediately after World War II....

Identification of a fibrous mineral, two samples of which were retrieved from a small open pit at abandoned mine workings located 2.5 km west of Rowland Flat in the Barossa Valley, on the bank of the North Para River, was made using X-ray diffraction...

This report presents the results of a Terranechron [registered brand name for this proprietary technique] study of detrital zircons from modern stream sediments of the Gawler Craton. The Terranechron approach involves obtaining uranium - lead decay...

After two years of negotiation with traditional owners and the Anangu Pitjantjatjara Land Council, the Geological Survey Branch of PIRSA's Minerals, Petroleum and Energy Division (MPE) commenced stratigraphic drilling on the 15th May 2002, in the...

The proposed Lake Gairdner 'section 12 determination' area has the potential to host significant mineral deposits. The area lies close to two major geological boundaries; to the immediate north is the Yerda Shear Zone, and to the west, the Yarlbrinda...

A field mapping project was set up by PIRSA to investigate the age, origin and emplacement history of newly discovered [by Goldstream Mining NL on EL 2222] volcanic rocks within the Mount Grainger Anticline, close to the town of Oodla Wirra. Outcrop...

Over the period from 1955 until 1976 an outcrop of Ordovician porphyritic rhyolite was quarried for road-sealing aggregate and rail ballast from two quarries at Mount Monster, 12 km south of Keith. The total recorded production was 548,000 tonnes....

The Mount Woods Domain (sometimes termed Mount Woods Inlier) is located ~850 km north of Adelaide along the Stuart Highway. The nearest major population centre is Coober Pedy, which lies ~70 km north-west of the northern domain boundary. Geologically,...

Reconnaissance investigations of outcropping rocks of the western and central Mulgathing Complex reveal a series of pelitic and psammitic sedimentary rocks, interleaved with generally mafic to intermediate composition meta-igneous lithologies. The...

Seven samples of Proterozoic basement rocks, representing syn and post-tectonic leucocratic melts that formed during the Kimban Orogeny within the Donington Suite and within cross-cutting Tournefort Metadolerite mafic dykes on the southernmost Eyre...

Detailed petrological descriptions of 16 surface and near surface samples of intrusive ?igneous rocks obtained from nine localities spread around Terowie, Eurelia and Bangor have shown that they are intensely altered and weathered, making confirmation...

Gem-quality varieties of beryl occur rarely in South Australia and exist in insufficient quantities to be of current economic interest. Non-gem grade beryl, by contrast, is a widespread accessory mineral in many pegmatites of South Australia, but, at...

The aim of this report is to provide a summary of the present status of the geology of the Olary Domain, Curnamona Province. It gives a comprehensive, referenced description of all known interpretations of Willyama Supergroup basement stratigraphy,...

The Square Kilometre Array (SKA) is a proposed radiotelescope receiver network that, when constructed, will have an effective collection area of one square kilometre, making it up to 100 times more sensitive than any present-day instrument on Earth....

In his two month - long technical secondment from PIRSA to Canadian major nickel explorer and producer Inco Ltd, the mode of genesis of the Reid Brook Zone of the Voisey’s Bay nickel-copper mineralised magmatic system was analysed by the author using...

Includes abstracts with the following titles: 1) How magnetotellurics (MT) works, and an overview of new central Australian MT results (Kate Selway) 2) Latest MT traverse results: western Gawler Craton (Stephan Thiel) 3) A constrained 3D...

This field guide presents an introduction to the geology and tectonics of the south-eastern Gawler Craton, particularly as observed at the Corny Point locality. Topics covered include the detrital zircon age distributions within the Corny Point...

ELA 2002/00154 is made up of three geographically separate sub-areas aligned in a north-easterly direction along the Bulgunnia Shear Zone. Neither the northern nor the central sub-areas have any basement rock outcrop, with the depth of younger cover...
