The Paleozoic to Mesozoic Southwest Margin is an under explored region of the continental margin of Australia and includes the Southern Carnarvon, Perth and Mentelle Basins, as well as the Naturaliste and Wallaby Plateaus. This study presents new interpretations of basement domain distribution, composition and structural geometry beneath the Southwest Margin basins. Basement is defined as the economic basement for petroleum systems and represents all igneous and metamorphic rocks of Late Neoproterozoic/Early Cambrian age and older, as well as any younger plutonic intrusions and Mesozoic oceanic crust (e.g. Nicholson et al., 2008; Borissova et al., 2010a; Jones et al., 2011). The interpreted maps extend from Naturaliste Plateau in the south to the Southern Carnarvon Basin and Wallaby Plateau in the north. In addition, they link the Archean Yilgarn Craton and surrounding Proterozoic mobile belts in the east through to the Early Cretaceous oceanic crust of the Indian Ocean to the west, and are therefore not constrained by the coast line or crustal type.
