Folding at Bude

Cornwall, UK

Sea cliffs (up to ~ 25 m) high and wave-cut platform in the sandstones and shales of the Carboniferous, Bude Formation, ~ 680 m south of Bude Harbour and the "Whaleback". The beds show Variscan folds and related faults. Some folds are upright and others have gently-dipping hinge planes. Faults are common in the hinges. For a description of the folds see Sanderson (1979). The outcrop provides an excellent example to examine the interplay between faulting and folding during deformation.

Single Fault & Fold Structure, Bude

An upright angular anticline in sandstones and shales of the Carboniferous,  Bude Formation, exposed in a sea cliff ~ 40 m high at Upton, ~ 1.5 km SW of Bude. Folding appears to be accommodated by extensional and contractional faults in sandstone beds on the hinge and southern limb.
