This report presents the results of a Terranechron [registered brand name for this proprietary technique] study of detrital zircons from modern stream sediments of the Gawler Craton. The Terranechron approach involves obtaining uranium - lead decay...

Includes abstracts with the following titles: 1) How magnetotellurics (MT) works, and an overview of new central Australian MT results (Kate Selway) 2) Latest MT traverse results: western Gawler Craton (Stephan Thiel) 3) A constrained 3D...

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...

High precision geochronological analyses of metamorphic and inherited magmatic zircon grains, which were obtained from stored percussion drillhole samples of a garnet gneiss that occurs within the Commonwealth Hill magnetic anomaly, north-western...

Reconnaissance investigations of outcropping rocks of the western and central Mulgathing Complex reveal a series of pelitic and psammitic sedimentary rocks, interleaved with generally mafic to intermediate composition meta-igneous lithologies. The...

The prevailing model of the crustal-scale architecture of the Musgrave Province (Lambeck and Burgess, 1992) proposes a Moho depth offset of 20-25 km beneath the Musgrave Province to explain early teleseismic arrivals and a regional gravity high. This...

In South Australia, Cambrian massive salt deposits of the eastern Officer Basin occur in troughs lying along the western and north-western margins of the Gawler Craton, and are considered to have been deposited in marginal to open marine environments....

The aim of this report is to provide a summary of the present status of the geology of the Olary Domain, Curnamona Province. It gives a comprehensive, referenced description of all known interpretations of Willyama Supergroup basement stratigraphy,...

In his two month - long technical secondment from PIRSA to Canadian major nickel explorer and producer Inco Ltd, the mode of genesis of the Reid Brook Zone of the Voisey’s Bay nickel-copper mineralised magmatic system was analysed by the author using...

The middle Palaeoproterozoic rocks (2000-1800 Ma) on southern Yorke Peninsula are part of the Cleve Subdomain in the eastern Gawler Craton, which is separated from the younger Moonta Subdomain by the Warooka Fault Zone. The rocks contain a group of...

Stratigraphic drilling has been undertaken by PIRSA in the South Australian portion of the northern Murray Basin to investigate the stratigraphy and sedimentology of the Cainozoic sedimentary sequences, as well as the heavy mineral sand potential of...

A regional geological interpretation of newly-acquired magnetic data for the majority of the Musgrave Block (central Australia) has been compiled at 1:250 000 scale. This report outlines the methodology and results of interpretation. Highlights of...

The great majority of lower Palaeozoic rocks in the Stansbury, Arrowie and Warburton Basins are of Cambrian age, although a few Early Ordovician fossils have been reported from drillholes in the sub-surface Warburton Basin. The Cambrian is the only...

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...

Seven samples of Proterozoic basement rocks, representing syn and post-tectonic leucocratic melts that formed during the Kimban Orogeny within the Donington Suite and within cross-cutting Tournefort Metadolerite mafic dykes on the southernmost Eyre...

The WINTINNA 1:250 000 mapsheet area lies between latitudes 27° to 28° South and longitudes 133°30’ to 135°00’ East. This ~16 400 square km area includes the Marla and Cadney Park settlements, and is crossed by the Stuart Highway and Adelaide to...
