Structure styles and tectonic evolution of the Abrolhos Sub-Basin, Perth Basin, Western Australia

Abstract

Based on examination and re-interpretation of 2D seismic and well data, three groups of faults were recognized in the Abrolhos Sub-basin: a) major normal faults transecting the Permian, Triassic and Jurassic, b) small normal faults developed in the Early Permian, and c) small normal faults developed in the Triassic and Jurassic.
