Abstract

A refleotion traverse was shot across the centre part of the Giralia Anticline in the Carnarvon Basin of Western Australia, in an attempt to verify the unconformity between Mesozoic and Palaeozoic sediments shown by a previous traverse across the northern part of the anticline. Shallow seismic events recorded were of good quality and correlated very well with surface geology. They also indicated two faults in places where steep dips in surface beds might, by anaJogy with the northern end, be expected. Deep events were in general of poor quality and inconsistent. However, over approximately a mile of the traverse, they were of good quality and indicated nonconformity with the shallow events.

Lineage

The Giralia Anticline extends for about 65 miles from the head of the Exmouth Gulf sou-chwards to the Lyndon River, in the Carnarvon Basin, Western Australia. During September, 1951, a seismic party of the Bureau of Mineral Resources completed a reflection traverse (Traverse "A") across the northern part of the anticline. The major conclusion from this survey was that an angular unconformity exists between the Mesozoic sediments in which the anticline had been mapped, and the underlying Palaeozoic sediments. The structure at depth below the axis of the surface anticline and beneath the unconformity was shown to be synclinal. To verify the existence of this unconfol"'mity, reflection Traverse "C" was shot during October and November, 1951, at Cardabia, about 22 miles south of Traverse "A".
