Migmatites are complex, high-grade crystalline rocks that have formed by partial melting. They have been recognised within the crustal rock record across most of geological time, are seen to be developed in various tectonic settings, and can affect a...

The subject field excursion performed in August-September 2000 in part mimicked that held by the GSSA during September 1997, but included 6 additional stops programmed for Day 1 (31st August 2000) to examine Archaean geology at the southern tip of...

Interest in an area near Mount Christie Siding was stimulated by the 1993 MESA Barton Bedrock Drilling Programme, which detected anomalous gold, chromium, base metals and platinoid metals in layered ultramafics. Initially, tenement-wide calcrete...

Gold and copper deposited in the desert sand - covered Archaean basement terrain of the north-western Gawler Craton were the targets of exploration within a contiguous group of licences. Calcrete sampling by hand dug holes or vehicle mounted auger...

Calcrete sampling under an earlier Exploration Licence (EL 2077) in the Moonbi area, 160 km north-west of Tarcoola, had returned an anomalous gold sample of 13 ppb Au. As part of Dominion's brownfields exploration programme for gold resources to...

[ Note - here is only Part 2 of an abstract comprised of 3 separately indexed parts ]. During the third licence year of EL 1971, the joint venturers continued to conduct exploratory drilling of new gold-in-calcrete anomalies that were delineated by...

[ Note - here is only Part 3 of an abstract comprised of 3 separately indexed parts ]. During the fifth licence year, infill calcrete sampling performed at the Monsoon SW prospect (96 samples taken at 100 m x 100 m spacing) delineated two high order...

The Harris Greenstone Domain bedrock drilling program - Phase 1, carried out during May to August 2001, has determined depths to basement, the basement lithology, and has outlined areas of anomalous gold, nickel and chromium geochemistry within...

Geochronology enables us to determine the age of rocks and minerals. The variety of isotopic geochronological techniques give complementary information on, for example, the timing of igneous or metamorphic crystallisation, as is often the case for the...

This report presents the results of a study jointly conducted by the Geological Survey of South Australia and CSIRO Mineral Resources which aimed to enhance the expression of geological structure in geophysical images and to derive depth to magnetic...

Relinquished portions of an exploration tenement lying south-west of Lake Phillipson yielded no anomalous geochemical results (max. 5 ppb Au) from regional calcrete sampling on a 1.6 km-spaced grid, and contained no identified areas of high priority...

Reconnaissance mapping and sampling of an area of poorly exposed Precambrian crystalline basement north of Kingoonya has shown that the regional geology is dominated by intensely folded, discontinuously outcropping banded iron formations that are...

This report presents the results from zircon SHRIMP U–Pb geochronology on seventeen quartzofeldspathic samples from the central-western Gawler Craton. The samples were collected from stratigraphic units mapped as the Archaean to early...

This report book contains SHRIMP zircon U-Pb geochronological data obtained between July 2007 and June 2009, for 10 metasedimentary and meta-igneous rocks from the Mulgathing Complex of the north-estern Gawler Craton. The geochronological study was...

This geotechnical workshop of seminars and core displays, which was held over two days on 5-6 December 2002, aimed to highlight recent collaborative research between PIRSA [MER], Geoscience Australia and the South Australian mineral industry that has...

This regolith material hand specimen atlas displays 246 images of 212 regolith samples which have been collected over the last 30 years by the authors, present and past Geological Survey of South Australia (GSSA) staff and members of the Cooperative...

Shallow Precambrian crystalline basement underlies the greater part of the BARTON 1:250 000 map area. Thicker Neoproterozoic, Cambrian and Carboniferous Permian sediments occur in the northwest, with the southern margin bounded by the Karari Fault...
