Heavy minerals are mined from two Cainozoic fossil strandlines in the southern Perth Basin. These arcuate, sub-parallel shorelines are situated on the Swan Coastal Plain, and are remote from the modern coast. The Capel shoreline is located 7 km inland and the Yoganup shoreline, 15 km inland, is adjacent to the arcuate-northwest facing Whicher Scarp, at the southern boundary of the plain. In the Yoganup shoreline, high-energy beach environments have concentrated heavy minerals by reworking sand from the Lower Cretaceous Leederville Formation. Heavy minerals were deposited in thin, shallowing-upward sequences along wave-dominated, eroding shorelines cut into pre-Cainozoic sediments.
