Abstract

Techniques for recording deep crustal reflections were developed on an experimental seismic survey at Mildura, Victoria and Broken Hill, NSW, during September to December 1968. The survey was carried out preparatory to a seismic reflection survey on the 'Geotraverse' project, a project initiated by the Australian Upper Mantle Commitee to study the Earth's crust and upper mantle along a line across the Precambrian shield in Western Australia.

Lineage

Following recommendations made by the International Union of Geodesy and Geophysics in 1960, many countries throughout the world initiated projects to study the Earth's upper mantle. The Australian Upper Mantle Committee, which was formed to foster and if necessary co-ordinate national projects, has reported on the work in this field up to the end of 1967. In 1965 the Committee recommended that a national project should be undertaken to study the Earth's crust and upper mantle along a line, designated the 'Geotraverse', across the Precambrian shield in the southern part of Western Australia. The Bureau of Mineral Resources (BMR) undertook to assist in this project by carrying out seismic, gravity, and magnetic surveys along the Geotraverse. For several years, attempts to record deep crustal reflections have been made by BMR seismic parties working on conventional sedimentary basin exploration. Deep crustal reflection events were recorded some areas at reflection times down to that expected for the Mohorovicic (Moho) Discontinuity. The recordings made at Mildura suggested that this would be a suitable area in which to carry out experimental work to develop recording techniques applicable for major deep crustal reflection seismic test survey at Mildura, Victoria and at Broken Hill, NSW, from September to December 1968 to develop recording techniques prior to the work on the Geotraverse project in Western Australia.
