19.5 Kennett River - Emerged Platform

This information has been developed from the publications:
  • Sites of Geological and Geomorphological Significance in the Western Region of Melbourne (1986) by Neville Rosengren
  • Sites of Geological and Geomorphological Significance on the Coast of Port Phillip Bay (1988) by Neville Rosengren.
  • Sites of Geological and Geomorphological Significance in the Shire of Otway (1984) by Neville Rosengren.
Geological heritage sites, including sites of geomorphological interest and volcanic heritage sites, are under regular revision by the Geological Society of Australia, especially in the assessment of significance and values. Reference should be made to the most recent reports. See the Earth Science Heritage (external site) section of the Geological Society of Australia website for details of geological heritage reports, and a bibliography.

Location:19-516198. Road cutting immediately north of the Great Ocean Road bridge across the Kennett River.

Ownership:

Crown land (Road Reserve).

Geomorphology:

The road cutting reveals a flat surface cut into the Mesozoic rocks and covered by landslip and fan deposits. An incision into the surface filled with rounded boulders has been termed a gulch by Gill (1973) who interpreted the surface as an emerged (interglacial) platform. This is one of several similar features identified as emerged platforms by Gill which occur in cuttings on the Great Ocean Road between Cumberland River and Browns Creek. Their age and actual mode of origin remain uncertain.

Significance:

State. Coastal features that suggest different sea levels in the past are of particular interest in studies of the tectonic and geomorphic evolution of the Otways. This site is clearly displayed and is a valuable reference and research site in this regard.
