South Australia

Abstract

South Australia has a relatively simple coast whose general trend and outlines reflects the regional structure. The nature of the rocks exposed in the coastal zone has determined the amount of erosion. Describes formation of the coastal dunes, more than 80% lime. Most of the coast is exposed to strong westerlies. Coastal forms include cliffs (with little coastal plain), dunes, stacks and sea caves, smooth and flat platforms, and the possibly doline formation of Waterloo Bay. Gives details of the coastal morphology of each region. Other features include granitic inselbergs, boulder beaches (Kangaroo Island) and longitudianl desert dunes. (C.J.U.)
