Deposit: A granite pegmatite dike strikes N50E and cuts pre-Cambrian metadiabases, hornblende schist, and gneisses for a distance of 600 ft. Maximum width of the dike is 70 ft; the average is 40 ft. In places, quartz and white feldspar show a graphic structure. Fine-grained aggregates of quartz and feldspar enclose some pink microcline crystals several inches in diamter. Some muscovite books are up to a foot wide but contain numerous dark iron spots. Tantalite-columbite crystals are associated with green beryl along fractures in the wall rock. Black tourmaline crystals up to several inches long are found in metadiabse and schist wallrock and as fine-grained veinlets in the pegmatite. Andradite(?) garnet is a minor accessory mineral. (Bull. 50, p. 132-133)
