Dune calcarenite and shore platforms at Cape Otway, Victoria

Auteur :
BIRD, E. C. F.

Description :
Cape Otway is a bold headland cut in Lower Cretaceous sandstones, bordered by cliffs and shore platforms. It is partly overlain by Pleistocene dune calcarenites and Holocene calcareous dunes resulting from eastward migration of aeolian sand from beach sources on the western shore. Locally, this material has spilled over the eastern shore, where there are sectors of cliff and shore platform cut in Pleistocene dune calcarenite, interrupting the Lower Cretaceous outcrop. It is deduced that the Pleistocene dunes spilled over an old cliffed coastline and on to a shore platform that had emerged as the result of sea level lowering. The present coastal features are thus very close to Pleistocene coastal features (cliffs, shore platforms) developed when the sea stood at almost the same level. (The A.).
