Abstract
The coastal landforms of the Townsville area indicate an evolution which can be traced back to at least the last interglacial high sea level phase. A maximum sea level of approximately 15 feet was attained during this late Pleistocene transgression. It was accompanied by a sub-humid climate in which pedimentation was a major process. This dry climate was maintained during at least the early part of the regressive phase, but became more humid during the maximum of the glacial stage. The rise in the level of the sea during the Holocene has been paralleled by a desiccation of climate. The Holocene transgression in the area reached a maximum level of about 12 feet approximately 4250 years ago, leaving well-defined traces of this level on the mainland and off-shore islands. Landforms and deposits may be indentified with each of the climatic and eustatic oscillations described. A morphoclimatic influence is indentified in past and present landforms of the area.
