L. N. Warr & B. Durning write: Although the modelling of the Padstow Confrontation is controversial, the papers of Andrews et al. 1988 and Selwood & Thomas (1988) show general factual agreement. It is accepted that within the area of polyphase deformation constituting the confrontation zone, folding, ductile shearing and thrust faulting represent the interaction of two regional patterns of F1 folding. First folds to the south of the zone (F1s) face northwards, whereas to the north the first folds (F1n) face south.
During our NERC-sponsored 1:10000 Mapping of the BGS Camelford sheet, a regional scale south-facing F1n syncline has been recognized which approximates to the St Minver syncline of Reid et al. 1910. The importance of this early structure has not been recognized by Andrews et al. 1988 and we believe it is crucial to the understanding of the chronology of events within the confrontation zone. North of Polzeath, Andrews et al. (1988, p. 780, fig. 6) have constructed a south-facing anticline with a long right-way up limb between Tresunger's Point and Pentire Point and a short overturned limb from Pentire to Gravel Caverns. We question the existence of such an anticlinal fold because the strata between Tresunger's Point and Gravel Caverns can be seen to be regionally overturned. This section forms part of the northern overturned limb of the St Minver syncline which continues to south of Polzeath; the shorter normal limb occurs south of Polzeath at Greenaway's Beach. We consider this to be the first phase of
