Abstract

The Bureau of Mineral Resources seismic party carried out a seismic survey in the Bonaparte Gulf area of north-western Australia between 16th June and 13th October, 1956. The initial objects of the survey were to obtain regional information on the thickness of the sedimentary rocks and on the tectonics of the Bonaparte Gulf Basin, and to establish the applicability of the seismic method in the area. During the course of the survey the party was directed to transfer its attentions to obtaining some detailed information on the Spirit Hill Anticline. This latter work was carried out in response to an application by Westralian Oil Pty. Ltd., which was anxious to select sites for a test boring programme. The seismic results indicate a maximum thickness of sediments of about 20,000 feet in the Carlton Basin and 14,000 feet in the Burt Range Basin. The rocks in both these basins have been folded to a considerable extent and the reflections suggest unconformities within both basins. The seismic reflection method proved successful in indicating geological structure at depth in most of the areas tested.

Lineage

The seismic party set up camp at the abandoned Ninbing homestead on 16th June and began operations on 20th June. The seismic traverse was begun at S.P.1 on the Weaber Group. about 5 miles to the south-east of Ninbing, and continued in a north-e23ter1y diroction through a break in the Weaber Range. As no reflections were obtained north-east of S.P.9, surveying of this portion of the traverse ceased at S.P.48. The survey was then continued to the south-west of S.P.1, beginning at S.P.54, a quarter of a mile from S.P.1. This part of the traverse extends as far as S.P.126 (drilled in hard Upper Proterozoic rocks) and reflections were obtained over most of its length. Two cross traverses, each one mile long, were completed through S.P0.. 57 and 71.^The first gave horizontal reflections and the second indicated a north-west component of dip of about 10°. In a further effort to obtain information on the northeastern part of the traverse, pattern shots of 13 holes and 36 holes were fired at S.Ps. 33 and 28 respectively, but no reflections were obtained. Refraction surveying on this portion of the traverse was also unsuccessful.
