Wiebenga, W.A. & van der Linden, J., 1953. Gravity survey in the Fitzroy Basin, Kimberley Division, Western Australia, with special reference to the Nerrima structure. Record  1953/064. Bureau of Mineral Resources, Geology and Geophysics, Canberra.

Abstract

The Fitzroy Basin is situated south-east of Derby in the Kimberley Division of Western Australia. Results are given of a semi-detailed gravity survey which was made of the portion of the basin between longitudes 123°40' and 124°30' and latitudes 18°05' and 18°40'. The survey disclosed a large basin structure at least 7,000-8,000 feet deep and a few minor anomalies which may prove important. It is not known whether the higher density formation at 7,000-8,000 feet depth in the basin represents Pre-Cambrian basement or sediments of Devonian or Ordovician age. The position of, and displacement on, the Fenton Fault system were indicated. A detailed gravity survey of the Nerrima structure confirmed the existence of faults which had been mapped by the Bureau's geological and seismic parties, but was unable to determine the depths to which these faults penetrated. Seismic refraction work and test drilling are recommended south of the Fenton Fault, between Barnes' Flow and Mt. James, to disclose the nature of the higher density formation. Recommendations are also made for an extension of the detailed gravity survey to areas in which anomalies were revealed by the semi-detailed survey.
