Bigg-Wither, A.L. & Davies, J.S., 1964. L053 Westbourne seismic reflection and refraction survey, south of Tambo, QLD, 1961. Record  . Geoscience Australia, Canberra.

Abstract

Aeromagnetic and gravity surveys were made in the Tambo-Augathella area by Magellan Petroleum Corporation in 1959 and 1960 respectively. A probable fault shown in the magnetic interpretation is almost coincident with a zone of steep gravity gradients which was interpreted as indicative of a fault or of steeply dipping strata. However, the normal gravity interpretation would indicate a deeper cross-section to the south-east of this zone, whereas the magnetic interpretation suggests that the fault is downthrown to the northwest. The present survey was undertaken by the Bureau of Mineral Resources to find out which interpretation was the more probable. A reflection seismic traverse was shot at right angles to the closed gravity 'high' and across the zone of steep gravity gradients. Results show that the closed gravity 'high' is the expression of an anticline and that the zone of stoep gravity gradients is caused by steep dip to the south-east on the flank of the anticline. The gravity interpretation is therefore found to be more representative of actual conditions.

Lineage

A seismic survey was undertaken by the Bureau of Mineral Resources during 1961 in the Westbourne area to the south of Tambo, Qld. The area lies in the northern half of the area covered by the:"Augathella sheet of the 1:250,000 map series. It is in the north-eastern portion of the Eromanga Basin which forms the western portion of the Great Artesian Basin. Aeromagnetic and. gravity surveys were made under the Commonwealth Petroleum Search Subsidy Act 1959 in the Tambo-Augathella area by Magellan Petroleum Corporation in 1959 and 1960 respectively. There was little agreement between the magnetic and gravity interpretation. The object of this seismic survey was to try to find which interpretation was the more representative of actual conditions. It was planned to use both refraction and reflection methods of seismic exploration to provide structural information across a steep gravity gradient coincident vdth, but in the opposite sense to, a fault interpreted from the magnetic results.
