Abstract

A description is given of lateral variations displayed by the Cenomanian Limestone in the cliffs, landslips and beach-blocks between Haven Cliff and Pinhay Bay. By comparison with the better-exposed sections around Beer it is suggested that, as in the Beer district, the lateral variations in thickness and lithology reflect periclinal folding during Cenomanian times. The axes of the elongated periclines in the Beer District have a more nearly north-south trend than those east of Seaton. This swinging round of the periclines is ascribed to the resistance offered to a fold system developing under northerly directed compressive forces by the Cornubian Massif in the west.
