This report provides a summary of high-precision chemical abrasion-isotope dilution-thermal ionisation mass spectrometry (CA-IDTIMS) U-Pb geochronology performed on zircon grains from five samples of Hiltaba Suite granites collected at locations...

A new generation, second edition MARREE 1:250 000 scale geological map and its explanatory notes have been published. These documents represent the conclusion of the Geological Survey of South Australia's latest geological mapping program (1993 to...

SA_STRAT is the department’s computerised database of stratigraphic units, comprising named formal stratigraphic units and unnamed mapping units. All current stratigraphic units are tagged with a GIS Search Code unique to each unit and used...

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,...

Investigations aimed at revising the stratigraphy of the Mount Woods Domain in the north-eastern Gawler Craton have identified numerous metasedimentary and intrusive units. The dominant metasedimentary package has been classified and named the Skylark...

The Corunna Conglomerate is a sequence of unmetamorphosed fluvial to shallow marine sediments, comprising conglomerates, sandstones and siltstones, which were deposited in active fault grabens in the eastern Gawler Craton. It is found on the...

The Mineral Systems Drilling Program (MSDP) was a $3.5M cash and $4.11M in-kind collaborative drill program involving government, researchers, service providers and the minerals industry. The objective of the MSDP was to further the understanding of...

This geochronological study was undertaken within the scope of the Mineral Systems Drilling Program (MSDP), a program that was aimed at improving the understanding of the geology and prospectivity of the southern Gawler Ranges margin area on northern...

Proterozoic basement outcrops consist of syn and post- Kimban Orogeny granitoids, volcanics and basic dykes. Their rock type geochronology, field relationships and regional correlation are reported. Previous economic mineral investigations, plus...

An interpretation of intrusive dykes of Gairdner Dyke Swarm for South Australia. As these dykes are largely hidden below younger sediments and soil, the dataset is synthesised from subsurface drillhole and geophysical data, combined with limited...

During two separate sorties conducted over the period 2 October to 22 March 2018, most of the LAKE EYRE 1:250k map sheet area was flown under contract to the SA Government and Geoscience Australia as part of the PACE Copper Gawler Craton Airborne...

The SHRIMP zircon dating study described herein was undertaken as part of the National Geoscience Agreement (NGA), as a collaborative research project between the Geological Survey of South Australia (GSSA) and Geoscience Australia (GA). Eight samples...

The St Peter Suite has been previously interpreted to have formed in a subduction-related setting; however, there are limited data with which to assess this interpretation. This report comprises two parts. The first is a summary of Sensitive High...

A strong total count radiometric anomaly (to 10 x background) was encountered on the western shoreline of Lake Torrens, about 20 miles south-east of Andamooka, during the course of reconnaissance aerial radiometric surveying. Detailed tests to...
