HyVista Corporation was contracted by PIRSA during July 2012 to process HyMap airborne hyperspectral scanner data acquired over the Mount Painter region of SA on 28/3/1998. The nominal pixel size acquired was 4.5 m x 4.5 m, within a surveyed area of...

The northern Flinders Ranges region is underlain by rocks predominantly belonging to two contrasting geological provinces: the metamorphic and igneous Palaeoproterozoic to Mesoproterozoic Mount Painter and Mount Babbage Inliers, and the sediments of...

This publication highlights how the availability of minerals is crucial to providing the basic requisites of life, or else, to fundamentally contributing for the manufacture of vital requisites such as food, clothing, heat, light and shelter, in order...

South Australia has had a very long geological history traceable back for over 2000 million years. It has areas of ancient basement rocks and of younger rocks representing most of the geological column, which are exposed at the surface or have been...

South Australia's famous desert opalfields supply about 80% of the world output of precious opal, with current production coming almost entirely from the major fields at Andamooka, Coober Pedy and Mintabie, each of which is expected to increase output...

This handbook is a selection of shortened reports by geologists of the South Australian Department of Mines and Energy dealing with some of the semiprecious and ornamental stones in this State. It is not intended to be a comprehensive review of these...

The opal occurs 15 km S of Mintabie in both bedding plane partings and vertical joints in the Wallatinna Formation a basal unit of the Early Cambrian Observatory Hill Beds. Small quantities of precious opal were found but potential is limited.

The purpose of this data package is to provide end-users with the GIS datasets used for the 2009 modelling of mineral potential in the Northern Flinders Ranges. The package contains subsets of SA 1:100 000 scale surface geology (polygons) and...

XRD, X ray powder photography, electron probe microanalysis and ICP atomic emission spectrographic analyses were carried out on thermally altered rocks. The high temperature origin of the mineral assemblage in the more strongly altered rocks is...

The subject report gives the results of two aspects investigated by Amdel regarding the treatment of South Australian oxide copper ores, viz. 1) the collation of leaching data for various mineralogical types of copper ores, that are available in Amdel...

Base metal and gold exploration undertaken over a lengthy period since 1980 in the Yudnamutana Hill area, 20 km north-west of Arkaroola, has comprised detailed geological mapping of major basement and cover stratigraphic units and known mineral...

Following recognition of the likely young age of the sources of the Abminga area magnetic anomalies, and the discovery of a number of diamond indicator minerals in sediments to the west of the Peake and Denison Ranges, the Allandale joint venture...

Results of reconnaissance geochemical sampling of outcrop and lag gravels of ?Birksgate Complex ferruginous quartzites within the eastern Musgrave Block did not justify further exploration for potential Broken Hill-style exhalative Pb-Zn-Ag deposits.

Previous drilling by WMC at the Kartanya prospect, 30 km west of Rudall in the central-southern Eyre Peninsula, yielded several high grade Fe intersections with up to 1% P and 140 ppm Zn. Reassaying of drillhole samples returned reduced levels of...

Interpretation of available SADME/BMR airborne magnetic survey data, and subsequent ground magnetic and gravity surveys to define five targets, were conducted in the area between Watson Siding and Ooldea, prior to drilling two rotary percussion holes...

As part of a regional search for diamondiferous kimberlite, stream sediment sampling of ?54 sites in the Wharton Hill area failed to reveal any kimberlite indicator minerals. However, heavy mineral concentrates from samples taken at four sites in the...

CRA's acquisition and interpretation of aeromagnetic and ground magnetic surveys, plus its gravel and stream sediment sampling, have successfully located a few kimberlites in the Truro area, 70 km north-east of Adelaide, where a large number of...

Recent company reconnaissance studies have shown the presence of anomalously high Ta and Nb in sodic granites in the Mount Painter area. Herein a preliminary account is given of the field relationships, petrology, geochemistry, mineral chemistry and...

Reconnaissance geological mapping of existing, previously quite productive opal workings in the White Hill area of the Stuart Range 'Breakaway' country, 100 km south-east of Coober Pedy, was followed by exploratory and infill narrow-hole auger deep...
