8. Frenchman Gully Peridotite

This information has been developed from the publications:
  • Sites of Geological and Geomorphological Significance in Central Gippsland (1981) by Neville Rosengren, M.S McRae-Williams and S.M Kraemers,
  • Sites of Geological and Geomorphological Significance on the coast of Port Phillip Bay and in the Catchment of Westernport Bay (1984, 88) by Neville Rosengren.
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:423302. Three kilometres north-north-west of Aberfeldy, 2.5 kilometres north-east of Violet Town.

Access:

Walk from Violet Town Track.

Ownership:

Crown Land.

Geology/Geomorphology:

A peridotite dyke is exposed in Frenchman Gully. The exposure is largely moss covered but is recognisable by the large rounded boulders which contrast with the surrounding soils developed on Norton Gully Sandstone.

Significance:

State. Peridotites are rare in Victoria and the Frenchman Gully outcrop is the largest known in the state.

Management:

Access to the peridotite dyke is difficult as it involves a strenuous walk down steep gradients from the Violet Town Track. This affords the site some protection. Excavation or mining in the area of the dyke must ensure that the exposure is not obscured.
