Granite pegmatite with Y as dominant rare earth.

The dyke consists of white to grey plagioclase and a large mass of white to
grey, glassy quartz containing large pure crystals of pink or grey microcline. Production in 1943 and 1944 reportedly totalled 8639 tons of quartz and 1525 tons of feldspar (Storey and Vos 1981b p. 164). Both sunstone (Hewitt 1967a p. 21) and zircon (Traill 1970 p. 623) are found here.
