Raitt, J.S. & Turpie, A., 1965. L065, L066, L068 & L069 Southern Carnarvon Basin seismic reflection and refraction survey, WA, 1963, 1964. Record  . Geoscience Australia, Canberra.

Abstract

A seismic reconnaissance, traverse was surveyed for 20 miles along an east-west line,. 10 miles 'north of -Carnarvon, as part of a regional investigation of the southern part of the Carnarvon Basin, W.A. Both reflection and refraction techniques were used, and the results were Correlated, where possible, with the known formations in the Pelican Hill bore. Several reflecting horizons could be followed although reflections from below the level of the Cretaceous/Palaeozoic unconformity were badly interfered by multiples. The refraction method was successful, and recorded three main refractors with velocities of 14750.ft/sec, 18400 ft/sec, and 20,280 ft/sec. The main feature of the section obtained is a broad antiform within the Palaeozoic sediments, shown particularly by the 20 2 280 ft/sec refractor, which is_a good marker. for structural mapping. This marker has been tentatively correlated with the Dirk Hartog Dolomite, which would suggest that the strata underlying the Gneudna Formation in the Pelican Hill bore belong to the Nanyarra Greywacke rather than the Tumblagooda Sandstone. Overall the profile of the 20 2 280 ft/sec marker has a slight west dip from about 4000 feet at the eastern end to about 5000 feet at the western end of the traverse. The Cretaceous/Palaeozoic unconformity was fairly flat at a depth of about 1500 feet. Indications from the reflection cross-section and from the profile of the 18,400.ft/sec refractor are that the sediments between the two above horizons are similar in structural attitude to the deeper horizon.

Lineage

During the months of July and August 1964, the No. 2 seismic Tarty of the Bureau of Mineral Resources (BMR) carried out a seismic survey along the southern-boundary of Boolathana Station 10 miles north of Carnarvon. The work done an this traverse forms part of a more general seismic investigation of the southern part of the Carnarvon Basin. In particular this traverse was designed to examine the stratigraphic and structural position of the Devonian sediments encountered in the Pelican Hill bore. The traverse was laid along a fence track, but access was hampered by heavy rains, which flooded the many clay-pans along its length. Work was conducted from a camp situated on the traverse, where it crossed - the north-west coastal highway 14-miles from Carnarvon.
