The Coompana Drilling Project was the culmination of a number of years of precompetitive geophysical data acquisition, analysis and interpretation. It set out to retrieve new basement samples from beneath the Nullarbor Plain that would allow program...

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...

Exploration for Proterozoic sedimentary-hosted mineral and energy resources can greatly benefit from geochronological methods that date the depositional age of sedimentary rocks that predate the Early Cambrian evolution of biomineralizing organisms....

The Mesoproterozoic (~1590–1586 Ma) Gawler Range Volcanics (GRV) comprise a sequence of A-type dominantly felsic volcanic rocks which were extruded in the central part of the Gawler Craton as part of a volcano-plutonic Silicic Large Igneous Province...

This report presents geochemical constraints on the evolution of the Minbrie Gneiss and Carpa Granite, two magmatic units occurring in the southern Gawler Craton. These two units were previously assigned to the Palaeoproterozoic Lincoln Complex,...

This data package is a compilation of recent exploration company data (see Env 6858), and some SADME data, including quartz-vein geochemistry, drillhole analytical data, fluid inclusion data, and a summary of U-Pb and lead isotope analyses. No attempt...

Age determinations on 5 granulites produced a metamorphic age of 1564 - 97 Ma, and an age of 1545 - 73 Ma on 7 gneisses. They do not support previously assigned ages based on lithological correlations, but indicate a metamorphosed ?Early Proterozoic...

Hallett Cove is one of South Australia’s foremost natural science treasures. Exposed examples for prime geological concepts of superposition of strata, depositional unconformities (representing time breaks), and folding and faulting of sedimentary...

The Tarcoola Goldfield region is located in the central Gawler Craton, and forms the northern portion of the Central Gawler Gold Province. Gold deposits underlying the Tarcoola Ridge and adjacent areas have been exploited by in excess of 50 historic...

The National Argon Map is an AuScope-funded pilot project (2020–2021). The project aimed to compile a national-scale 40Ar/39Ar geochronology map and to analyse new samples to fill the gaps in national coverage of this dataset. The Geological Surveys...

The Cultana basement 3D Geological Model covers a region which includes the Roopena, and western half of the Cultana, 1:100,000 mapsheet areas. The subsurface geology that has been modelled comprises a succession of deformed Palaeoproterozoic...

During the period 23 February to 14 June 2017, most of the ANDAMOOKA 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 Survey. The intent of this survey...

During the period 19 January to 12 May 2017, near-coast onshore parts of the NULLARBOR and FOWLER 1:250k map sheet areas were flown under contract to the SA Government and Geoscience Australia as part of the PACE Copper Gawler Craton Airborne Survey....

During fine weather intervals within the period 21 June to 30 September 2018, the southern half of the CHILDARA 1:250k map sheet area and the onshore two-thirds of the STREAKY BAY 1:250k map sheet area were flown under contract to the SA Government...

The latest knowledge of the surface geology of South Australia is displayed on the 2020 edition of the state geology map newly released by the Geological Survey of South Australia (GSSA). It is a product of the GSSA’s ongoing statewide geological...

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...

A 74 station, single profile ground gravity survey was acquired by personnel of the Geological Survey of South Australia (GSSA) during September-October 2020 in an area to the south-southeast of Manna Hill township. All gravity readings were made at...

The Curnamona Province basement 3D Geological Model is a product of PIRSA's early 3D modelling trials conducted using 3D GeoModeller software. The work began with identifying the statigraphic units that were to be modelled. Due to the regional scale...
