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 in the Gippsland Lakes Catchment (1984) 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 for details of geological heritage reports, and a bibliography.


730250. Benambra Creek north of Pendergast Lookout, 14 kilometres north-east of Benambra.


Scarp formed by faulted lineament, alluvial basin and gorge in Triassic syenite.


Beloka Road.


Partly Crown Land and partly Private Land.


Ordovician sediments have been metamorphosed by the intrusion of Triassic syenite in this area. The syenites terminate the Buenba Fault and are well exposed in a short gorge section of Benambra Creek. The Buenba Fault lineament is marked by a prominent scarp.


Three major physiographic features occur in this area. Benambra Creek has cut a broad alluvial valley, flanked by terrace, in Ordovician sediments. The alluvium is bounded on the west by a prominent scarp and in the south by Triassic syenites of the Mount Lemster Complex. The syenites are evidently more resistant to erosion than the surrounding Ordovician sediments and down cutting by Benambra Creek in these rocks has produced a short gorge section.


Local. The effects of varying lithology and structure on stream valley shape are well displayed at this site.


Because of the area covered by the site, the value of the significant geomorphological features is unlikely to be seriously reduced by localised land disturbance.
