Transported Aboriginal Artefact Material, Perth Basin, Western Australia

Abstract

THE Perth Basin in south-western Western Australia contains numerous sites of surface and near-surface accumulations of rock flakes, and some of the material has almost certainly been carried for many hundreds of miles. The basin is filled with Proterozoic and Phanerozoic sediments, but outcrop is poor and large areas are covered by sand. In the east, the Perth Basin is bounded by the Precambrian Yilgarn Block, and in the southwest by the Precambrian Leeuwin Block. To the north lie the Precambrian Northampton Block and the sedimentary rocks of the Carnarvon Basin (see Fig. 1).
