Clevedon Shore
Clevedon Shore is a 0.38 hectare geological Site of Special Scientific Interest adjacent to the Severn Estuary at Clevedon, North Somerset, notified in 1991.
It is the side of a mineralised fault, which runs east-west adjacent to the pier, and forms a small cliff feature in dolomitic conglomerate on the north side of Clevedon Beach, containing cream to pink baryte together with sulphides. The minerals identified at the site include: haematite, chalcopyrite, tennantite, galena, tetrahedrite, bornite, pyrite, marcasite, enargite and sphalerite. Secondary alteration of this assemblage has produced idaite, Covellite and other Copper sulphides.
The site is listed as a Geological Conservation Review site as several of the minerals found here are rare, in particular the beudantite. The presence of copper and arsenic is unusual for the Mendip district.
