Silurian rocks on the beach in Ireland

To continue the investigation of rocks at Ferriters Cove, I followed the curve of the cove to the right (or roughly northwards), where the Silurian strata become higher, exposing their sharp thin edges as they thrust through the beach surface. At high tide level they are bare – no seaweed or encrusting organisms. As the rock layers pass into the base of the low cliff, they retain their steep angle. However, immediately above the bedrock is a thick layer of broken shards lying almost horizontally but with some perturbations; I don’t know how they got like this but wonder if it has something to do with glaciation. This layer of broken pieces is overlain by softer, looser sediments – possibly more geologically recent aeolian or wind-blown accumulations. The clean, dry rocks have pleasing pale green-grey and orange colours.
