Title: Applying geophysics for 3D paleochannel imaging.
Abstract: In predominantly arid Western Australia, paleochannels contain sand-dominated intervals that host water that is of potential interest to farmers, explorers and indigenous people. In many cases, the depth of the paleochannel marks the depth of cover above potentially prospective bedrock. The Cenozoic-era Yangibana paleochannel, composed dominantly of sands and clays, is incised into the Proterozoic granitic basement of the Gascoyne Province. This study demonstrates how the integration of different geophysical methods can improve the currently available paleochannel maps of Western Australia. The methods used in this study add depth information to the paleochannel geometry and increase its resolution.
