amblygonite
phosphate mineral composed of lithium, sodium, and aluminum phosphate [(Li,Na)AlPO4(F,OH)], that is an ore of lithium. It occurs in lithium- and phosphate-rich granitic pegmatites, often in very large, white, translucent masses. It has been mined at Keystone, S.D., and in South Africa, Zimbabwe, and several other countries. Clear material from Hebron, Maine, has been faceted as a gemstone.
