GCR Site /SSSI/CGS name: Hollicombe HeadCorbyn’s Head CGS (proposed)
Grid reference: SX898619- SX908633
Description (GCR statement of Interest or CGS description) and lithostratigraphy :
[Provisional] Permian: Foreshore and cliff exposures between Hollicombe Head and Corbyn’s Head provide key, readily accessible exposures of conglomerates and sandstones of the Permian ‘red bed’ sequence of the Torbay Breccia Formation. These exposures include the stratotype of the Corbyn’s Head Member at Corbyn’s Head. The member is characterised by mediuim to coarse grained sandstones, commonly cross-bedded and varying in colour from reddish brown to buff and pale greyish, which pass upwards into conglomerates. The latter include clasts of sandstone, quartz and limestone. Thin beds of reddish or greenish mudstone are also present and some
show mudcracks. The sandstones indicate deposition in seasonal rivers and the conglomerates suggest more proximal alluvial fan conditions. Reasons for registration as a RIGS site: The site shows a sandstone dominated sequence within the breccias and conglomerates of the Torbay Breccia Formation, including the stratotype of the Corbyn’s Head Member, of regional lithostratigrafical importance. The area has a high educational potential due to easy access in the heart of the Torbay seafront [Exeter Group: Torbay Breccia Formation (including Corbyn’s Head Member)]
