    RareElement Granitic Pegmatites Rare Earth and Critical

    Pegmatite bodies that contain minerals in which these elements are essential structural constituents constitute less than 1 to 2 of all pegmatites in a given pegmatite-bearing terrane, and the economic production from many such bodies is limited by their small size i.e., they may be economic in grade, but not for mechanized mining. Because pegmatites are found in cratons and orogenic belts, however, pegmatite-hosted
