CORNISH GRANITE - Hingston Down Quarry, Cornwall
« backCORNISH GRANITE
Hingston Down Quarry, Gunnislake, Cornwall
A nice sample of granite with sparkling crystals of muscovite mica.
Cornish granite varies in texture but is usually speckled with white feldspar crystals, translucent quartz, and muscovite and biotite mica. It has been widely used as a building stone in Cornwall and as a decorative stone worldwide.
Granite now forms the backbone of Cornwall, part of the Cornubian batholith, created during the Variscan mountain building episode in the late Devonian and Carboniferous periods.
