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. {"type": "Polygon", "coordinates": [[[115.5, -31.5], [116.25, -31.5], [116.25, -31.0], [115.5, -31.0], [115.5, -31.5]]]} 115.5 116.25 -31.5 -31.0 AU-WA HVC_144637 Published_External Seismic Data seismic survey Seismology and Seismic Exploration geophysics petroleum exploration seismic reflection Download the file (misc) documentDigital Download the file (misc) ZIP Unnamed resource documentDigital HTML
