Abstract

Recent geophysical and geologic investigations have revealed the presence of belts of gentle domes and anticlines, possibly related to strong transcurrent basement faults, in the Mesozoic-early Tertiary formations of the central and western Great Artesian Basin of Australia. In this region, a thick sequence of marine Cretaceous shales includes possible petroleum source beds and also constitutes an impermeable capping to highly porous Triassic and Jurassic sediments which overlie or wedge out against unmetamorphosed marine Paleozoic strata, some of which are known to be bituminous.
