The structural evolution of the Northern Carnarvon Basin, Northwest Australia
MetadataShow full item record
3D and 2D seismic data from the Northern Carnarvon Basin provide an opportunity to analyze the structural evolution of the basin. This is a rift-dominated basin, formed by five phases of extension (Pre-Top Permian, Top Permian, Base Jurassic, Middle Jurassic, and Late Jurassic Extension, versus only the four previously identified) and the Base Cretaceous inversion across the Northwest Shelf of Australia. The first deformation by listric fault initiation in the basin resulted in a newly defined Pre-Top Permian Extension, generating the Exmouth, Dampier, Barrow and Beagle Sub-basins. The magnitude ...
