Abstract

The Giralia and Marrilla Anticlines are in the north-western part of the Carnarvon Easin, North West Division, Western Australia. The Giralia Anticline extends southward for 80 miles from Exmouth Gulf to Salt Lake; the maximum outcrop width across the two anticlines is 18 miles. The Giralia and Marrilla Anticlines are maturely dissected asymmetrical folds of low relief which consist of sediments deposited in Cretaceous and Tertiary time in a shelf area possibly contiguous with the geosyncline of Timor and East Celebes. The Giralia Anticline is the second largest of twelve closed anticlines in the post-Palaeozoic sediments of the Carnarvon Basin north of the Gascoyne River. The vertical closure of the Giralia Anticline on the top of the Boongerooda Greensand is 700 feet, and the closed area is 230 square miles. The anticlines were folded at four different periods, viz. between upper Eocene and lower Miocene, lower Miocene, between lower Miocene and Pleistocene, and Pleistocene or post-Pleistocene.
