Mount Aitken

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 The review of eruption points was based on an earlier unpublished manuscript Catalogue of the post-Miocene volcanoes of Victoria compiled by O P Singleton and E B Joyce (Geology Department, University of Melbourne 1970).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

Moggs Hill

Private land:

Vineyard, residence, grazing, abundant outcrop.

Type 9:

Composite lava and scoria volcano.


Mount Aitken is the most prominent of a group of eroded volcanic hills in the Sunbury and Gisborne area. It is asymmetrical with a steep southern face with prominent parallel lava ridges, a small flattened summit with a shallow depression and a long gentle lava flow sloping to the north and west down to the level of the surrounding plain. Details of the geology are not known but the form of the hill suggests similarity with Mount Kororoit i.e. a scoria and lave core covered by final lava flows. The form of the volcano may be due to erosion of a scoria rim that once surrounded a lava-filled crater from which the lave tongue issued to the north. The removal of the scoria rim left the lava as a capping on the summit of the cone.

501 m; 75 m.

State:

Mount Aitken is one of the best examples of this type of eroded volcano. It shows a stage in volcanic landform development that is not widely represented with erosion of a summit lava flow from a scoria cone.
