The eastern Gawler Craton is the location of the Olympic Cu-Au Province, a world-class metallogenic province known for iron oxide - associated copper-gold (IOCG) deposits such as Olympic Dam, Prominent Hill and Carrapateena (Skirrow et al., 2007; Reid, 2019). The Olympic Cu-Au Province is a vast region some 600 km in strike length, with several sub-regions of distinctive geology and mineralisation style. The focus of this report is the southern region of the Olympic Cu-Au Province, in particular the geology of the Yorke Peninsula. This region contains the historical Moonta - Wallaroo mining district, the Hillside deposit in the east, and a range of other prospects and smaller deposits (Conor et al., 2010). This report describes new geochronological and geochemical data obtained from samples that were collected mainly from the Yorke Peninsula. The aim of this project has been to characterise the age and chemistry of the crust in this region. The samples selected are of the Barossa Complex, which is the Proterozoic basement unit of the Adelaide Rift Complex, the Donington Suite, the Wallaroo Group, and granites interpreted to belong to the Hiltaba Suite. These are the main stratigraphic units of the Yorke Peninsula region and, in the case of the Barossa Complex samples, of the reworked eastern margin of the Gawler Craton. As the samples' origins in time extend from the oldest (Donington Suite, c. 1850 Ma) to the youngest (Hiltaba Suite, c. 1580 Ma) stratigraphic units, they provide an insight into the crustal evolution of the region through the later Paleoproterozoic and into the early Mesoproterozoic. The new data have been collected as part of a collaborative project arranged between the Geological Survey of South Australia and the China Geological Survey, Nanjing Key Center. The subject report describes the samples analysed and their analytical results, and provides a brief discussion of their geochronological interpretation. All of the U-Pb dating data are in provided in Appendix 1, and in addition they are available online via SARIG https://map.sarig.sa.gov.au. Whole rock geochemical data and Sr-Nd isotopic data were also collected on selected samples, and they are presented in Appendix 2.
