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.

Location:

260930. 4 kilometres north-west of Mt Deddick.


Abstract:

Silver lead mineralization associated with quartz reefs in Lower Silurian granitic rocks.

Access:

Deddick Track.

Ownership:

Crown land (Snowy River National Park).

Geology:

Lower Silurian granitic rocks in hornblende are intruded by feldspar porphyry, mica diabase dykes and quartz ribbon veins. The latter are associated with silver/lead mineralization.

Significance:

Local.

Management:

This is an old mining area and good collectors specimens may be obtained but control on excavation and removal of material is necessary. The area could be displayed as a site of historical and geological interest.
