Abstract

The Caswell Sub-basin hosts some of Australia's most valuable hydrocarbon reservoirs that relate to Permo-Triassic inversion, however, little is known about the nature and origin of these events. Results from 2D seismic data and restorations suggests the basin initiated in the Palaeozoic, guided by the collapse of a Proterozoic duplex. The basin margins were subsequently inverted in the latest Permian and intermittently throughout the Triassic, indicating boundary faults accommodated bulk strain during deformation. Mesozoic narrow rifts overprinted the pre-existing wide rift basin along necked zones in the crust, culminating in the separation of Argoland from the North West Shelf.
