Abstract

A gravity survey of 3883 stations covering an area of 4000 square miles was conducted in southern Queensland and northern South Australia by GeophySical service International's Party 662 for Delhi Australian Petroleum Ltd, from July to December. 1962. Most of the gravity stations were approximately one-half mile apart but 824 were one-quarter mile stations. In general, stations wel'e set in a four by fifteen-mile grid, although in some areas, particularly in the south-eastern portion of the survey. closer control was established. The survey was designed to determine the major gravity anomalies in the prospect area and to seek structural leads in an area almost devoid of outcrop. Fifteen gravity anomalies of significance were discovered eight of which are related to basement topography while the remainder indicate features within the sedimentary section. Computed sedimentary thicknesses ranging from 3500 feet to 21500 feet were obtained. Seven major anomalies related to basement features are recommended for further detailed geophysical investigation. In this summary, the results of the survey are presented on the Bouguer gravity map at a scale of 1:250 000. The geophysical operation undertaken in the Alton Downs area of the Great Artesian Basin. Queensland and South Australia, was subsidized under the Petroleum Search Subsidy Act 1959-1961.
