This document aims to establish an appropriate geological framework and resource potential baseline for DEM's knowledge about lime sand on Kangaroo Island (KI), by showing and discussing what new lime sand resource areas are available, based on the...

Much of the Gawler Craton (in South Australia) is covered with soil and other regolith materials that hide basement rocks and hinder mineral exploration. In the western parts of the Gawler Craton, for example, weathered basement rocks are covered by...

Stratigraphic drilling has been undertaken by PIRSA in the South Australian portion of the northern Murray Basin to investigate the stratigraphy and sedimentology of the Cainozoic sedimentary sequences, as well as the heavy mineral sand potential of...

The middle Palaeoproterozoic rocks (2000-1800 Ma) on southern Yorke Peninsula are part of the Cleve Subdomain in the eastern Gawler Craton, which is separated from the younger Moonta Subdomain by the Warooka Fault Zone. The rocks contain a group 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...

Komatiitic greenstones were first recognised in South Australia from drillcore at Lake Harris on the Gawler Craton by Mines and Energy SA personnel in 1991. Subsequent petrography and detailed aeromagnetic data interpretation led to targeted drilling...

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...

The central Gawler Craton is blanketed by thin sedimentary cover that ranges in age from Neoproterozoic to Quaternary. Locally, though, such cover can reach a maximum of ~500 m thickness in Permian glacial valleys or rift structures. This guide...

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 Musgrave Province is largely incorporated within the Anangu Pitjantjatjara Lands and includes cratonic crystalline middle Proterozoic basement rocks of the Musgrave Province proper, as well as mantling younger sedimentary rock successions...

The Niton Corp. XL-700 series portable XRF analyser was trialed by members of the Musgrave Team, PIRSA Geological Survey Branch, to determine its viability for use in the field by DME and exploration company personnel. Analyses of soil (250 micron...

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...

The results of a 1982 State-wide hydrogeochemical survey showed the Musgrave Block to be anomalous and potentially mineralised. In 1997 a groundwater quality survey was undertaken for the remote communities in the Anangu Pitjantjatjara Lands. Water...

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...

The Boomerang gold prospect is located 650 km north-west of Adelaide in undifferentiated Proterozoic rocks incorporated within Archaean Harris Greenstone Belt mafic lithologies of the Gawler Craton. The prospect was originally discovered using...
