Location:

018493. Spring Creek, west of Buchan Caves Reserve.

Abstract:

Fairy Member Sediments.

Access:

Walking track from Buchan Caves Reserve.

Ownership:

Crown land.

Geology:

The Fairy Bed Sediments are the most important sedimentary sequence in the Gelantipy Rhyodacite. In Spring Creek the sequence is approximately 30 m thick and is composed primarily of limestone. The limestone contains a fossil fauna including conchostracans, ostrocods, gastropods, coprolites and fish teety as well as some plant fragments. A small excavation midway up the northern spur of the creek exposes siltstone and agglomerates of this formation. These are however poorly exposed.

Significance:

Regional. Best exposure of Fairy Member in Buchan area.

Management:

Site quality would be enhanced by the clearing of debris from hillside excavation. The removal of the limestone in Spring Creek should be prohibited.
