Abstract

Maps, plots and data sheets of average source rock richness, quality and maturity for five Mesozoic time slices are presented for offshore Northwest Australia (Carnarvon to Arafura basins). These maps/data facilitate regional assessment of the source rock potential of the region, and provide a framework for future exploration of the region's petroleum systems. The maps were compiled at a scale of 1:3 million, and are supplemented by two-way-time isopach maps for each time slice derived from interpretation of Geoscience Australia's regional seismic grid of the area (approximately 35,000 line km). Age vs TOC, S2 and HI, and source rock crossplots were also compiled from screened raw Rock-Eval pyrolysis data and displayed as inserts in the maps. The maps and open-file data used in the compilation of the maps can be viewed directly, or printed as a hard copy.
