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.

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:

Unconformity (A-A'), between Silurian sediments (S) and Buchan Caves Limestone, (Dla) at Old Paddock Creek tributary.

Abstract:

Angular unconformity between Buchan Caves Limestone and Silurian sediments.

Access:

Walk from Old Hut Creek Track.

Ownership:

Private land.

Geology:

An angular conformity between Buchan Caves Limestone and Silurian sediments is exposed at this site, where thick, bedded, dark grey Buchan Caves Limestone overlies thinly bedded Silurian siltstone and shales of the Cowombat Siltstone. Towards Mt Walterson, a conglomerate lens in the Cowombat Siltstone is exposed in the creek bed. Two caves are known on the ridge to the north and a breached doline on the spur south of the creek.

Significance:

Regional. The relationship between the Buchan Caves Limestone and the Silurian sediments is well displayed at this site. The caves may prove to be more extensive.

Management:

Land use which would obscure the outcrop should be prohibited. Small-scale quarrying in the area of the contact would enhance the site by increasing the quality of the display. The management principles outlined for limestone regions apply to this area.
