Detail of granite at Knockvologan
Granite at Knockvologan beach - this alkali-granite, approximately 414 million years old, is composed of potassium-rich orthoclase feldspar, and smaller amounts of plagioclase feldspar, together with quartz and biotite mica. At Knockvologan, the granite contains a darker material called tonalite, an igneous rock which was formed at the same time as the granite.
