Heaghney Hill

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 The review of eruption points was based on an earlier unpublished manuscript Catalogue of the post-Miocene volcanoes of Victoria compiled by O P Singleton and E B Joyce (Geology Department, University of Melbourne 1970).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.

Lava hill.

Heaghney Hill is a lava mound resting on broad lava base. There are eroded flows to both the north and south forming ridges and small mesas. Dipping lava ridges (squeeze ups or dykes) are prominent and there is abundant outcrop in valleys lateral to the lava flow. The contact with underlying Ordovician sediments is well exposed in the valley of Deep Creek on the west of Heaghney Hill.
