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.

Mount Delegate (A), a monadnock of Ordovician sediments with radial drainage systems (arrowed).


Exposures of Ordovician sediments with associated pyrite mineralization monadnock and radial drainage pattern.


Mount Delegate Road.


Predominantly Private Land with a small enclave of Crown Land.


Ordovician sandstones and shales are exposed at the peak and on the steep eastern slopes. The sediment are fractures and crossed by quartz veins, some of which reach one metre in width. The veins are associated with sulphide and gold mineralization, and several abandoned shafts and adits remain on the eastern slopes of the mount.


The Mount Delegate monadock rises 400 metres above the surrounding plain. A radial drainage pattern has developed from this isolated peak. This pattern is disrupted to some degree by the orientation of the major streams, the Bendock River and the Haydens Bog Creek, along fault lines.
Regional. Mount Delegate is an unusual example of a monadock and together with the associated drainage characteristics is of considerable geomorphological interest.


Because of the area covered by the site the value of the significant geological and geomorphological features is unlikely to be seriously reduced by localised disturbance, e.g. road works, extractive industries or agriculture.
