L017 & L027 Cookernup seismic reflection and refraction survey, WA, 1955_1956
Seismic reflection traverses were surveyed across the Perth Basin at Cookernup, W.A. These traverses were planned to find the thickness and dip of the Basin sediments adjacent to the Darling Scarp and to discover any faulting or folding within them; also to determine the applicability of the seismic method as a tool for both regional and detailed investigation in this area. Seismic refraction traverses were surveyed to help in the solution of problems encountered in the interpretation of the reflection cross-sections.
The survey indicated a considerable thickness of sediments about 20,000 ft, at the eastern margin of the Basin near the Darling Scarp, and suggested tectonic structure that is not indicated in surface geology, The reflection traverses indicated that sediments (presumably Lower Palaeozoic or Precambrian) lying deep in the Perth Basin may continue underneath the Darling Scarp and abut the granitic gneisses etc. of the Western Australian Shield on an overthrust fault plane. The overthrust fault, if it exists, does not reach the surface, but is covered to a depth of possibly some few hundred feet by younger sediments and also by alluvium eroded from the Darling Scarp. Some reflection and refraction shooting was done in an attempt to test this and other hypotheses, but the results crc inconclusive. Gravity results strongly suggest a normal fault, and if normal faulting is the case, the reflections from beneath the outcropping basement are possibly derived from shear zones, Some probable 'reflected refractions' were also observed. There is scope for further seismic testing but it is considered that conclusive evidence could only be provided by drilling.

The Cookernup area, about 75 miles miles south of Perth, lies in the Perth Basin which extends from Cape Leewin in the south to Geraldton in the north. Gravity work by the Bureau of Mineral Resources, Geology and Geophysics in the Perth Basin (Thyer & Everingham, 1956; and Neumann & Flavelle, in preparation) indicates a considerable
thickness of sediments and shows steep Bouguer anomaly gradients in the vicinity of the Darling Scarp.
During February and March 1955 a Bureau seismic party carried out surveys in the Gingin area, about 45 miles north of Perth, and in the Cookernup area, to verify conclusions drawn from the gravity results, and to continue the study of the Perth Basin l using the seismic reflection method. This was part of a proposal to use the seismic surveys to assist in determining the thickness of sediments and the structure of the Basin at several locations. The Bureau seismic party revisited the Perth Basin in 1956 to do surveys at Busselton and Rockingham; additional work was done at Cookernup in 1956.
