A seismic reflection traverse was surveyed across the Perth Basin through the township of Gingin. The traverse was planned to give information on the thickness of the sedimentary section, the structure of the Basin, and the aplicability of the seismic method as a tool for both regional and detailed investigation. The traverse was chosen to cross a major negative gravity anomaly (-110 milligals at Gingin) and to cross the so-called "Hill River Fault". A considerable thickness of section was indicated (in excess of 17,000 feet) and tectonic structure, not apparent in the surface geology, was shown. A deep-seated anticline, the Gingin anticline, was discovered.
