Geophysical interpretation of the central Olympic Cu-Au province GIS Dataset
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.

The interpretation was done from airborne magnetic data and drillhole logging. The magnetic data are from numerous government and company datasets and were compiled by GA and PIRSA. Drillhole data are from PIRSA logs and logging by the authors. Gow's interpretation (1996: Geological evolution of the Stuart Shelf and Proterozoic iron oxide-associated mineralization: Insights from regional geophysical data. Unpublished PhD thesis) was the starting point for this work. Geological cross-sections derived from our interpretation were tested using ModelVision.
The model of depth-to-basement was calculated using the ANUDEM topographic modelling algorithm and was based primarily on drill hole data and the mapped limits of basement outcrop. No attempt has been made to smooth the depth-to-basement contours which have been computer-generated from the gridded model.
The vector data was digitised and compiled using ArcInfo 8.0.2. Depth-to-basement data was gridded and contoured using the Topogrid module of ArcInfo 8.0.2 and the Spatial Analyst extension of Arcview 3.2. Geophysical and depth-to-basement images were exported as BIL files from ER Mapper 5.5.
