[en] The features of lithium, rubidium and cesium distributions in preliminary separated metamorphogenic-metasomatic and ultrametamorphogenic intrusive facies of granites have been considered. In mineralogic and geochemic investigations the samples have been analysed by the flame photometry. From the data obtained the main differences are evident in the lithium, rubidium and cesium content. The lithium content is 2 - 4 times as low as its clark for granites and increases from the metamorphogenic-metasomatic facies to the intrusive one. The rubidium content in biotites increases with the total concentration of metal in rocks k-Feldspars are the main rubidium carriers in granites and the most part of rubidium atoms is connected with them. In this case biotite is a mineral-concentrator. Granites of the Byelorussian anteclis stand out for the low cesium content, 2.3 - 3.3 times as low as its clark for persilic rocks. Mean contents of this element slightly increase from the metamorphogenic-metasomatic series to the intrusive one. The features of rare metal distribution are supposed to be due to the trend of geological development and the conjugated geochemical processes in the crust
