The north coast of Cornwall has a distinctive geology that is unlike anywhere else in the British Isles. It is dominated by granite which forms the backbone of the Cornish peninsula. The outlying edges of this granite mass are made up mainly of slate which has very different physical characteristics. Both rock types, igneous and metamorphic, have been transformed over millennia by heat, pressure and the movement of the surrounding ocean.
