Port Phillip Bay Survey 1957–1963. Geology and geomorphology

Abstract

Port Phillip Bay lies in a tectonically controlled depression in which recurrent faulting has occurred from Palaeozoic to recent time. Stratigraphic and geophysical evidence indicates maximum vertical dosplacemtn in the sunkland of more than 2,000 feet.\rVariations in lithology and topographic relief affect the coastal landforms developed on the east and west. On the east coast, cliffs and shore platforms are more common than on the west; beaches are broader and off-shore bars are larger and more complex. Coastal sand ridges which are rarely developed on the east are common on the west......
