Summary:This Upper Carboniferous formation of SW England was deformed soon after being deposited and a complex geometry of folds and thrusts is seen. The deformation initially exploited slumped beds as decollement horizons and resulted in thrust movement to the N, associated with chevron folding, which continued, causing folding of thrust planes and cleavages. The sense of thrust movement changed from N to S and is seen as the effect of backthrusting associated with the migration of the deformation front to the N. [R.E.S.]
