The 2010 GOMA basement drilling program formed part of a collaborative ARC Linkage Project LP0882000 " Unearthing the marginal terrains of the South Australian Craton: Keystone of Proterozoic Australia " arranged between Primary Industries and...

A suite of intrusives (St Peter Suite - new name) along western Eyre Peninsula displays a wide range in composition, texture and relationships. The features are typical for mingling and mixing of felsic and mafic magmas, with U-Pb geochronology...

U-Pb zircon geochronology of the Nuyts Volcanics yielded an age of 1627 +/- 2 Ma, supporting a previous dating of 1631 +/- 3 Ma. The major and trace element compositions, as well as the presence of a tectonic fabric, suggest that the Nuyts Volcanics...

This Report Book contains zircon U-Pb geochronological data obtained between December 2006 and June 2007, for rock samples derived from the Gawler Craton of South Australia. The geochronological study was undertaken as part of the National Geoscience...

This publication has been compiled from a display prepared for the launch of SADME Bulletin 53, held at the Australian Mineral Foundation on 7 December 1987. The importance and diversity of commodities found in the Geosyncline are highlighted in the...

The geology of the Lake Gilles locale in the south-west of the PORT AUGUSTA 1:250k map sheet area is poorly understood. Outcrop of basement rocks there is sparse, and typically occurs along the margins of the salt lake, where it is highly weathered....

Brief description of sampling procedures and sites. All samples analysed by semi-quantitative spectrographic method for precious and rare earth elements. Results in appendix.

The major units present are Middle Proterozoic leucogranites, alkali granites and porphyries, overlain by Pleistocene Bridgewater Formation. Leucogranites contain up to 10% phenocrysts of potassium feldspar and bluish quartz, alkali granites contain...
