Approximately 30 square km of outcrop of Palaeoproterozoic basement rocks in the vicinity of Ameroo Hill were geologically mapped by the author at 1:10,000 scale, with the aim of identifying meso- and macroscopic rock structures and lithologically...

This report briefly describes the physical mineralogy, natural characteristics, current industrial applications, local production history and geology of occurrence of the mineral corundum, at 7 potentially economic, plus several other, apparently...

This report presents detailed industry-derived statistics on the State's output and sales values of earth resource commodities realised during the six month period ended 30 June 2006, and compares the data with that returned for the previous six...

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...

An emplacement age of 1497 ± 38 Ma for the felsic Spilsby Suite exposed on islands in southern Spencer Gulf is anomalously young with respect to magmatism elsewhere within the Gawler Craton, and is approximately 75 to 90 million years younger than the...

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...

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 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 deformed metasediments of the South Australian Willyama Inliers (in the southern Curnamona geological province) preserve petrologic evidence of a complex and protracted metamorphic history. To assist with unravelling this history, there currently...

The purpose of the project is to provide essential data on the hardrock extractive (construction material) resources supplying the Adelaide metropolitan area, in order to be able to: - Critically examine current hardrock supplies and resources and how...

At least 90% of the phosphate was leached with either nitric, hydrochloric or sulphuric acids. Products unsuitable for the surface preparation of steel. The most promising outlet would be for upgrading the P2O5 content of super phosphate fertilizer.
