Rocks at Swine Den south of Cullernose Point
Sandbanks Limestone, one of the oldest Carboniferous deposits (quarried in the foreground) is thrown into several 'whale-back' folds. The fold axes run north-south and their folds are asymmetric, being steeper on the west (shore) side. Between these folds and the Whin Sill of Cullernose Point there is another big fault and it has been suggested that horizontal movement on this fault might account for the whale-back folds with their asymmetry. The limestone contains fossil fragments of trilobites, crinoids (sea lilies), brachiopods and corals. A similar folding of the Sandbanks Limestone occurs north of Dunstanburgh Castle at Greymare Rock NU2522 : Greymare Rocks

Behind is the headland of Cullernose Point composed of the Whin Sill, a dolerite intrusion, which here shows well developed columnar jointing.
