Abstract

Seismic reflection studies in the Perth Basin, between the coast and the Darling Range, 30 miles north of Perth, were conducted in an attempt to derive a suitable recording technique for obtaining reflections when shooting on the Coastal Limestone formation, to investigate geological structure in the basin,and to supplement hydrological studies being madeby the Geological Survey of Western Australia. Experimental work occupying half of the survey period failed to yield a technique for obtaining seismic reflections on the Coastal Limestone, but led to reflections being obtained across the major part of the basin, Record quality with a fairly heavy technique was poor to fair in the western half of the basin off the Coastal Limestone but improved considerably to the east. A complex geological section in the west gave way to a more concordant thick synclinal section in the east, terminated at its eastern end by the Darling Fault. Of interest is an apparent anticlinal reversal of dip in beds lying deeper than 7000 ft,with the reversal axis near the centre of the major gravity 'low' of the basin.

Lineage

During the period mid-March to mid-June 1964, the No. 2 Seismic Party of the Bureap of Mineral Resources carried out a seismic survey in the Wanneroo - Bullsbrook area, approximately 30 miles north of Perth, Westekn Australia. Two east-west reflection traversea were recorded using a continuous profilingmethod: Traverse A, over the Pleistocene Coastal Limestone formation; and Traverse B to the east of the Coastal Limestone outcrops, on a Pleistocene sand formation. In previous seismic surveys in the Perth Basin, difficulty has been experienced in obtaining reflections when shooting on the Coastal Limestone, a thin (about 200 ft thick) Pleistocene formation which crops out in a narrow belt along the coast. In this survey, experimental shootingwas conducted in this formation in an attempt to develop a successful shooting technique: Traverse B was shot across the basin from the edge of the Coastal Limestone area to the Darling Escarpment (the eastern margin of the Basin) to investigate the structures of the Basin, and in particular to ascertain whether faulting of the type found in the Rockingham/Mundijong seismic survey in 1956 (Moss, 1962) was present.
