Abstract
The Upper Carboniferous Bude Formation of North Cornwall and Devon underwent deformation, beginning shortly after its deposition, which resulted in a complex geometry of folding and thrusting. The deformation initially exploited slumped beds as décollement horizons and resulted in a significant northerly translation of thrust sheets. The development of chevron folds, for which the area is famous, commenced at this stage but continued, causing folding of thrust planes and cleavages. During the deformation the dominant sense of thrust movement switched from a northerly to a southerly direction and this is interpreted as the effect of backthrusting associated with the northwards migration of the deformation front.This publication has 19 references indexed in Scilit:
