Brief description

A four and a half month seismic survey has been carried out in the Poole Range area of the Fitzroy Basin by C. G. G. where both the reflection and refraction methods have been tested. Reflection experiments lead to a high multiplication of geophones and shot-holes patterns. However, tests were too limited and too scattered to allow for definite conclusions regarding the best recording procedure. The refraction method has been used to provide information regarding the extension at depth of Poole Range surface anticline. The same method was used for a reconnaissance survey on the regional gravity anomaly 16 A. Besides shallow markers, two and sometimes three deep markers were followed simultaneously. The results obtained during the survey indicate that: Poole Range surface structure has no extension at depth; - Two high zones, separated by a narrow trough appear to correspond to the gravity anomaly 16 A. The eastern high zone is a wide dome with a closure of about 4,000 ft at the level of the deeper marker. The western high zone corresponds to a shelf-like area of the deeper marker. It is overlain by sedimentary formations where facies changes are suggested by rapid variations of the marker's velocities. This is the shallowest area of the survey with a 15,000 ft/ sec marker at a depth of less than 10,000 ft. Delimination of the most interesting structural locations would require the carrying out of supplementary traverses. A tentative interpretation makes the deeper marker a probable Proterozoic level with depths ranging from 15,000 feet to 30,000 feet. The two others might represent Devonian and Ordovician formations.
