British Geological Survey Petrology Collection sample number MC 7403. The deposit was investigated during the Second World War as a source for commercial grade muscovite for use in a range of electrical and other industries. A pegmatite is a very coarse-grained igneous rock with a grain size greater than three centimetres. Pegmatites often contain mineral suites that are otherwise rare such as lithium, beryllium and rare earths and are often economically important.
