(Volcanic Tuffs with cementstone band - 2007)
The cliffs at North Berwick are of Carboniferous age but are actually volcanic. The vast majority are unfossiliferious. At the middle of Oxroad bay, the cliffs are fine agglomerate green volcanic tuff, Yellow-weathering cementstone bands contain fish remains and pteridosperms.
Towards the east of the bay, near the castle, there is a Vent Agglomerate, red bedded tuffs with large blocks of large basanite boulders can be seen on the foreshore which are outside the vent.
