Short summary

This paper uses seismic reflection methods to image and better constrain fault and basin architecture at depth in a region of northern Australia thought to be highly prospective for oil and gas as well as sediment-hosted lead–zinc mineralisation. A better understanding of these architectural constraints is essential for the delineation of fluid pathways, barriers, and potential traps where these commodities may have accumulated.
