We had a great day out today at the Shap Pink Quarry in Cumbria hosted by Steve Elliot of Armstrongs Group. The site covers about 60-70 hectares and is quarried for road stone as well as rock armour. The granite intrusion is Devonian in age (415.6 +/-1.4 Ma) and is remarkable for its megacrysts of orthoclase feldspar which give it its pink hue. These often demonstrate Carlsbad twinning. Mafic inclusions - historically described as xenoliths - are very common and joints in the granite are often coated with pyrite.
