The stratigraphic correlation chart of the Northern Carnarvon Basin reflects the subsidence history of this basin. It has been dominated by simple thermal sag following the creation of the Exmouth, Barrow, Dampier and Beagle Sub-basins during the Early to Middle Jurassic rifting event. The simple thermal-sag model accounts for the post-rift sedimentary architecture of the Northern Carnarvon Basin, notably in areas starved of sediments. The depositional environments were dominantly siliciclastic deltaic to marine throughout the Triassic to Cretaceous. Carbonates dominate the Late Cretaceous to Cainozoic sedimentary sequences forming a blanket over the entire basin.
