Abstract

A field of Middle and Late Pleistocene coastal foredunes occupies much of western Eyre Peninsula, South Australia. The rolling surface reflects the morphology of the stacks of calcarenite dunes that underlie the area. Hardpan calcrete is well developed in relation to the present, as well as to earlier dune surfaces. The region is a typical karst. Some dolines, including several of the larger forms occur high in the local topography and are also aligned in groups. Low permeability calcrete horizons within the dune sequence have probably disturbed groundwater circulation and also form a stable framework preventing major collapse, and preserving both dolines and caves
