Towards the end of 1950, the deep bore which the Shell Development Company was drilling to test for oil on the Morella structure, 35 miles south of Rolleston, entered andesite at approximately 4000 ft. After boring about 200 ft into the andesite, the Company decided to abandon the hole. A new site for a test bore was selected on the Comet anticlinal structure, 60 miles north of Rolleston. Before proceeding with this new test, evidence was needed to ensure that neither a shallow basement nor volcanic rocks existed under this structure. The Bureau was therefore asked to shoot a refraction traverse over the anticline, in order to determine if basement rocks were likely to be present at a shallow depth. As a result the Bureau sent a seismic party to the area during January 1951. Fairly definite evidence was obtained of basement velocities occurring at a depth of less than 3000 ft, and after discussions, a decision was made not to proceed with the drilling of the Comet structure. The results have now been investigated in detail and are presented in this report.
