Abstract
This record contains zircon U-Pb geochronological data obtained between July 2001 and May 2003 on diamond drillcore from the Olympic Domain, Gawler Craton, South Australia. The data were collected as part of the Gawler Craton Project; a collaboration between Geoscience Australia (GA) and the Division of Mineral and Energy, Primary Industry and Resources, South Australia (PIRSA). The project aims to provide an improved geological and metallogenic framework for the Gawler Craton, with initial emphasis on the Olympic Domain. The term Olympic Domain (formerly 'Olympic Subdomain'; Daly et al. 1998) refers to the eastern extension of the Gawler Craton, concealed beneath Mesoproterozoic, Neoproterozoic and Cambrian sedimentary rocks of the Stuart Shelf. It also encompasses outcrop and subcrop of the Gawler Craton further south in the Moonta-Wallaroo region of the Yorke Peninsula. The sedimentary cover sequence of the Stuart Shelf is between about 300 and 1000 m thick, and the only knowledge of the underlying crystalline basement comprising the Olympic Domain is derived from exploratory drillholes. The long distances between drillholes impede inter-hole correlations. Thus U-Pb isotope dating of rocks intersected by (diamond) drillcore plays a key role in regional stratigraphic studies, establishing an absolute basis for temporal correlations across the Olympic Domain. This record describes the samples analysed and the analytical results obtained, and provides a brief discussion of their geochronological interpretation. The broader geological implications of the data will be published elsewhere.
