22. Mt. Ararat - Older Volcanics Eruption Point

This information has been developed from one or more of these publications:

  • Sites of Geological and Geomorphological Significance in the Westernport Bay Catchment (1984) by Neville Rosengren.
  • Sites of Geological and Geomorphological Significance in the Western Region of Melbourne (1986) by Neville Rosengren
  • Sites of Geological and Geomorphological Significance on the Coast of Port Phillip Bay (1988) by Neville Rosengren.
  • Sites of Environmental Significance in the Flood Plain of the Upper Yarra Valley Region (1983) by Neville Rosengren, Douglas Frood and Kim Lowe (as part of a study of Sites of Environmental Significance by the University of Melbourne for the then Upper Yarra Valley and Dandenong Ranges Authority).
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 (external link) for details of geological heritage reports, and a bibliography.



Location:Nar Nar Goon - 726861. Immediately north of the Princess Highway seven kilometres east of Pakenham.

Access:

Princes Highway.

Ownership:

Private land.

Geology:

Mount Ararat is the highest point of a north-south trending ridge of Older Volcanics basalt. It is conical in form and has been identified as an eruption point.

Significance:

State. This is one of number of Older Volcanics erosion residuals on and south of the ranges in the northern part of the Westernport catchment. It is one of the small number of localities identified as an eruption point of the Older Volcanics lavas.

Management:

Class 2. Quarrying could be permitted on the slopes as this would assist in displaying the nature of the eruption point. Extensive construction or close subdivision of the upper slopes and crest should be prohibited as this would mask the nature of the volcanic features.
