6. Farmers Road Quarry - Mirboo

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 (external link) section of the Geological Society of Australia website for details of geological heritage reports, and a bibliography.

Location:	287391. Three kilometres south-west of Mirboo.	Sites 8121-2 to 7
Access:	Farmers Road.
Ownership:	Private Land.
Geology/Geomorphology:	This large quarry provides a clear exposure of the Tertiary Older Volcanics. There are at least two flows of dense, columnar jointed basalt separated by white mudstone and black shale beds up to three metres thick.
Significance:	Regional. Clear exposures of the tertiary basalts are uncommon in the southern area of South Gippsland. In addition this quarry provides a clear exposure of the intercalated sediments, characteristic of the Tertiary Older Volcanics.
Management:	The general principles of quarry management apply here. In this quarry, a section of basalt and the intercalated sediments should be retained. This large, gullied spoil heap from this quarry which spills into, and partly blocks, the Farmers Creek highlights a major problem of quarry management.
