Development of a basin, doughnut and font assemblage on a sandstone coast, western Eyre Peninsula, South Australia

An assemblage of minor sandstone landforms, including rock basins, annular rims or doughnuts and miniature towers with crestal basins (fonts), is described from the Talia coast of western Eyre Peninsula, South Australia. The role of beach etching, the weathering of rock beneath moist beach material, in the sequential development of this assemblage is discussed. The possible role of beach etching in the development of some shore platforms, and in the shaping of angular unconformities and nonconformities covered by marine sediments, is also broached
