Abstract

Towa.:ccis the end of 1960 , the Bureau. of Mineral Resources, Geology and Geophysics made a brief seismic survey in the Winton area of Queensland to resolve an apparent contradiction between the interpretations of gravity and aeromagnetic results previously obtained in the area. Gravity and aeromagnetic results both suggested the occurrence of a large fault or fault zone about 20 miles north-west of Winton, but the gravity and aeromagnetic interpretations differed regarding the direction of throw of the fault. A nine-mile seismic reflection traverse was surveyed across the supposed fault. The seismic results indicate the presence of a large fault or monoclinal fold with dowthrown side nouth-wast as suggested by the gravity values and also a smaller fault or monocline about two miles south-east with downthrown side south-east. The variations in thckness of Mesozoic rocks caused by these features were insufficient to explain the observed Bouguer gravity anomaly values, but the seismic results left open the possibilitues that there may be a considerable thickness of pre-Mesozoic sedimemts north-west of the main monocline or fault. It is postulated that the steep gravity gradient observed may be due to a large fault whose main movement took place in pre-Mesozoic times. Indications are that there is 5000 to 6000 ft of Mesozoic sediments in tha area.

Lineage

From 28th November to 9th December 1960, the Bureau of mineral Resources, Geology and ,Geophysics did a brief seismic reflection survey about 20 miles north-west of Winton in the Great Artesian Basin, Queensland. The object of the survey was to resolve an apparent contradiction between interpretations of gravity and aeromagnetic results previouslly obtained in the area. Gravity and aeromagnetic results both suggested the occurrence of a large fault or fault zone with a south-west to north-east strike, but the interpretations differed on the direction of throw. A seismic reflection traverse about nine miles long was surveyed along the Winton-Cloncurry road, which runs in a north-westerly direction, so as to cross the supposed fault. The seismic traverse was situated on a lease area held by Magellan Petroleum Corporation. The aeromagnetic survey was made in 1956 by Adastra Hunting Geophysics Pty Ltd for Catawba Corporation, the previous holder of the Authority to Proopect. Prior to the Bureau's 1960 survey, no seismic work had been done in the Winton area.
