The purpose of this study was to determine the extent, thickness and facies of the Permian Arckaringa Basin where it overlies the Officer basin in central northern South Australia. Marine sediments provide important data for sea level curves, and coal-bearing strata can be analysed for vitrinite reflectance. Isopach and structure contour maps can determine the timing of structural events. All such information is necessary for conducting a comprehensive geohistory analysis of the region. The sources of data used for mapping included stratigraphic and other records from seismic upholes, coal exploration and stratigraphic/mineral exploration drillholes, which resulted in 92 points of reference spread across the study area. The derived contour maps were used to make inferences about regional structural trends and tectonic history.
