The Curnamona Province has been host to widespread magmatic activity, with several periods of granite emplacement recorded, variously extending from the late Palaeoproterozoic to early Mesoproterozoic. Mesoproterozoic granites and volcanic rocks occur extensively across the Curnamona Province, ranging in age from ~1600 to 1570 Ma. The volcanics were extruded over the eroded surface of the Palaeoproterozoic Willyama Supergroup. Some of the Mesoproterozoic granites and volcanics display similarities to the Hiltaba Suite granite and Gawler Range Volcanics (GRV) of the Gawler Craton. Classifying the granites and volcanic rocks into suites and supersuites, and determining the extent of each suite, may provide insight into new areas with potential for finding economic mineralisation, because geological knowledge of the systematic relationship between granite type and associated mineralisation is already well established (Wyborn et al., 1996). Many of the granites and volcanics present in the Curnamona Province have similar ages and share many geochemical characteristics with the Hiltaba Suite granites and the GRV of the Gawler Craton; hence there is potential for the existence of IOCG Olympic Dam-style deposits in the Curnamona Province. There is also a direct relationship of uranium, thorium and REE mineralisation with the granites formed in the Crocker Well region. Of equal importance is Cu-Au-Mo mineralisation in the Portia - Kalkaroo region, where there is a strong but indirect relationship between granites and mineralisation. Disseminated molybdenite is also reported from at least one granite body in the Olary Domain. Understanding the relationships between these granite suites and related mineralisation will allow for the identification of areas having untested mineral potential. The various granitic and volcanic suites, that may include granite, granodiorite, diorite, migmatite, monzonite, trondhjemite, adamellite, alaskite, gneiss, basalt, trachyte, rhyolite and gabbro rock types, are distinguished apart on the basis of existing and new geochemical data. Also available are new geochronological data, which place further constraints on the timing and duration of magmatism in the Curnamona Province during the Mesoproterozoic.
