Mount Pierrepoint

This information has been obtained from the report: Eruption Points of the Newer Volcanic Province of Victoria by Neville Rosengren. This report was published in 1994 and was prepared for the National Trust of Australia (Victoria) and the Geological Society of Australia (Victorian Division). The review of eruption points was based on an earlier unpublished manuscript Catalogue of the post-Miocene volcanoes of Victoria compiled by O P Singleton and E B Joyce (Geology Department, University of Melbourne 1970).

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 value. Reference should be made to the most recent reports. See the Earth Science Heritage (external link) section of the Geological Society of Australia website for details of geological heritage reports, and a bibliography.

Location:37 46 30S 142 03 30E (external link): 7322-3-4 (Tarrington) 930186. 3 km SE of Hamilton. Kurtzes Road.


Dundas

Land Tenure/Use:

Private land. Bare, grazing and water storage tanks. Small disused quarry on lower northern slope.
Type 1:Lava cone with crater.

The broad low basalt lava cone has a shallow crater open to the north. The lavas are deeply weathered and flow boundaries are indistinct. K-Ar dating of basalt from Mount Pierrepoint gave an age of 3.90 (+/-) 0.10 million years.

280 m; 30 m

Regional:
A good example of the degree of weathering and soil development on one of the earlier eruption points of the Newer Volcanics Province. This is one of a small number of lava flow volcanoes to have evidence of a crater.

Class 3:
Maintenance in rural land use will protect the significant values of the site.
