Coastal cliffs and foreshore, exposure site.
Boscastle to Widemouth SSSI, Cornwall, comprises a coastal section which provides excellent exposures of deformed Carboniferous sediments, folded during the Variscan Orogeny. The site is of major importance for research into the mechanisms and timing of different phases of deformation during the Variscan Orogeny. It is also a classic educational site for learning about structural geology because of the excellent exposure and is visited by numerous university and school parties. The site is robust and the only real threat to its conservation would be coastal defences.
