Abstract
A detailed mapping and geochemical and geochronological study of the Hiltaba Suite in the Tarcoola Region, South Australia, shows significant greater variation in composition than is allowable under the definition of Suite. By extending this work into the rest of the Gawler Craton using existing datasets, the Hiltaba ‘suite’ can be shown to be co-magmatic with the Gawler Range Volcanics. Together the magmatic rocks are grouped as the Gawler Range-Hiltaba Volcano-Plutonic event, and the intrusives themselves grouped as the Hiltaba Association Granitoids. A four-fold Supersuite classification is applied to both the intrusive and extrusive units. A great variation in compositions within the GRHVP reflects source and emplacement conditions. These variations can be correlated to different mineralisation styles observed in the Central Gawler Gold Province and the Olympic Copper-Gold Province.
