An interpretation of the pre-Neoproterozoic and Archean rocks of the central Olympic Cu-Au province of the eastern Gawler Craton based on calibrated gravity and magnetic data. The Olympic Cu-Au Province, of the eastern Gawler Craton, lies beneath the sedimentary sequences of the Stuart Shelf. Rocks of the basement are Late Archean metamorphics, and the Proterozoic Donington Suite, Hutchison Group, Wallaroo Group, Hiltaba Suite granitoids and mafic intrusives, and the Gawler Range Volcanics. Except for parts of the Gawler Range Volcanics, none of the basement crops out and is covered by sequences exceeding 3 km thickness, in places. Interpretation of units and structures was via gravity and airborne magnetic data. Some geological calibration was done by checking exploration drill logs or by examining the core. When core was examined, petrophysical properties were measured and used to constrain the interpretation.
