According to the rock-forming minerals, four types of rare-metal pegmatites are distinguished. type Imicrocline pegmatites, type II--albite- microcline pegmatites, type Ill--albite pegmatites, and type IV-albitespodumene pegmatites. The content of alkaline and rare elements in these types is not always similar, usually ranging rn rather narrow limits in well developed veins of the same types. The following elements are characteristic of the different types: type I-K, Be; type II-- K, Na, Ta, Be, Cs, Rb, Tl, and Li; type III--Na, Li, Be, T; Nb,and Sn; type IV--Na and Li, and sometimes Nb and Sn. The formatron of the different types and the different degree of their enrichment by alkaline and rare elements may be explained by the initial geochemical specificity of the pegmatite melts. (auth)
