A basaltic dike dipping into the cliff away from the camera viewpoint. Some concentration of plagioclase crystals can be seen in the centre of the dike. The dike is Palaeogene in age, related to the opening of the North Atlantic (and related locally to the Carlingford Igneous Centre), and intrudes near-vertical beds of Silurian turbidites of the Longford-Down Inlier (Southern Uplands in Scotland/N England)
