摘要：

Rare-metal Li-F-granitoids (Li-F-bearing granites, ongonites, and elvanites) are now established at six localities in Altai. In five cases they are spatially associated with the massifs of Late Paleozoic-Mesozoic granites of the Kalba-Monastyrka geochemical type, which are also distinguished in having more rare elements, in particular Li. Geochronological dating of Li-F-granites gives two groups of ages: 269-283 Ma for southwestern Altai and 195-183 Ma for Gorny Altai. Rare-metal mineralization is associated with Li-F-granitoids of Altai.
