9.6 Tertiary Gravels - Gellibrand

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:9-213310. Two kilometres south of Gellibrand and 100 m north east of Site 9.5.

Access:

Gellibrand-Beech Forest Road.

Ownership:

Private land.

Geology:

Gravel beds contained in the Dilwyn Formation include large pebbles of material that has not been derived from the Otway Group. Kenny (1938) suggested that some may have originated in the Grampians area but no further study of origin or mode of transport has been made since his work.

Significance:

Regional. The coarseness of the gravel beds is unusual in the Tertiary sediments of the Gellibrand area.
