Small anticlinal disturbances of the Bovey Beds appear to be confined to beds within 8 m of the ground surface. Some are sharp piercement structures but the majority are irregular domes of kaolin clay containing lignite. It is suggested that they are formed by periglacial process (congeliturbation) similar to that responsible for the involutions now recorded in many superficial and other unconsolidated deposits in southern England.
