Mount Warrenheip

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 The review of eruption points was based on an earlier unpublished manuscript Catalogue of the post-Miocene volcanoes of Victoria compiled by O P Singleton and E B Joyce (Geology Department, University of Melbourne 1970).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 34 30S 143 57 30E (external link); 7622-1-1 (Warrenheip) 600367. 9 km E of Ballarat. Forbes Road.

Mount Warrenheip.

Buninyong.

Land Tenure/Use:
Public land on top half, surrounded by private land. Access road to top. Forested, no outcrop.

Type 5:
Scoria cone with crater.

Mount Warrenheip is a composite breached scoria cone from which issued a number of lava flows. There is a deep, well-defined central crater which has been breached on the northern side. On the southern side, the cone rises abruptly above older weathered lava flows but the topography around the northern side is irregular as younger lava flows issued from here via the explosive breach of the cone. These lava are dated at 2.53 (+/-) 0.15 million years. Small parasitic lava vents occur around the base. With 170 m of local relief, Mount Warrenheip is one of the higher scoria cones in Victoria. The lavas include olivine-rich xenoliths and megacrysts of clinopryoxene and orthoclase. Road cuttings expose coarse volcanic agglomerate and thin pods of lava.

741 m; 170 m.

Regional:
A major example of a breached scoria cone although not as obvious as Mount Buninyong. It is one of the few major scoria cones substantially in public ownership and forested. It is an important megacryst site.
