Picture of Pillow Lava on Anglesey

Fantastic views, glorious beaches and interesting geological formations including pillow lava can be found on Llanddwyn Island on the Isle of Anglesey. The rocks are basalt pillow lava of the Gwna Group, which erupted beneath the late Precambrian to early Cambrian sea. Erupting lava chilled quickly against the water with the blobs of lava expanding like a balloon to form the shape we know as pillow lava. In combination with the limestones and lavas, Llanddwyn Island is one of the most spectacular field localities in the UK.
