Реферат:	eng: The geochronological and geochemical parameters of the Raduga muscovite-fluorite-euclase-beryl deposit, located within the Kizir-Kazyr zone of rare-metal magmatism, were determined. In contrast to other deposits and ore occurrences located in this zone and represented by alkaline granites enriched in rare-metal mineralization, the formation of the Raduga deposit is associated with the metasomatic transformations of carbonate rocks. The age of this deposit, estimated by Ar-40/Ar-39 dating of muscovite fromberyllium fluorite-muscovite greisens, is 469.3 +/- 4.5 Ma. It corresponds to the age of the ore-bearing alkaline granites. The dykes developed within the deposit are similar in composition to those within rare-metal alkaline-granite massifs, one of which is located a few kilometers from the deposit. The character of the Be-Li ore mineralization in the Raduga deposit is in good agreement with the geochemical specialization of the Early Paleozoic Kizir-Kazyr metallogenic zone. The revealed features of the relationship between the Raduga deposit and rare-metal deposits confined to alkaline granites suggest a variety of mechanisms involved in the formation of rare-metal deposits of the Kizir-Kazyr metallogenic zone. Thus, it allows us to expand the approaches for prediction and exploration of rare-metal deposits in the region.
