British Geological Survey Petrology Collection sample number MC 7383. At this deposit the mica occurs in a coarse dyke-like mass of white muscovite pegmatite twenty-five feet in width which cuts the highly injected pelitic Moine schists of the district. The body contains large masses of barren white quartz which particularly along the northern margin are accompanied by books of mica up to eight inches in length and two inches or so in thickness. The mica belongs to the ruby type and most of the books are perfectly clear and of excellent quality.
