Crackington Haven recumbent folds

A zoomed-in view of the base of the cliff on the north side of Crackington Haven, north Cornwall.

Grey shales and thin turbidite sandstones, (pale grey-brown) of the Crackington Formation (upper Carboniferous) have been strongly deformed into isoclinal recumbent folds by the Variscan earth movements at the end of the Carboniferous.
