This information has been developed from this publication:

  • Sites of Geological and Geomorphological Significance in the Western Region of Melbourne (1986) 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 section of the Geological Society of Australia website for details of geological heritage reports, and a bibliography.

Ripley Bridge - Basalt Pavement

Access:

Geelong to Bacchus Marsh Road.

Ownership:

Private land.

Site Description:

The channel of Little River is here cut into Newer Volcanics basalt. The basalt is strongly jointed and regularly jointed and forms a tessellated pavement in the stream bed.

Significance:

Local. This is a clear and readily accessible example of the nature and influence of jointing in the Newer Volcanics basalt.

Management:

Class 2. Small weirs, culverts or causeways across the channel would obscure the form of the pavement. These should be located away from the best areas of jointed pavement.
