Abstract: Isotope composition of graphite carbon in the main industrial vein and near-vein greisens of the Kalgutinsk rare-metal deposit (Mountainous Altai) has been studied. Formation of graphite is connected with allocation of carbon during partial oxidation of primarily restored ore-forming metal-bearing fluid. The content of Сorg in a vein - 0,036 %, in greisens - 0,022 %. Carbon is characterized by «light» isotope composition, ?13Сorg in a vein-23,9, in greisens - 25,3 ‰. The «weighting» of the element upwards on revolt of the vein, which is explained by fluid evolution, is revealed. Regular fractionation of isotopes in the system vein - near-vein greisen is established. Isotope fractionation varies in vein's sections, differs by capacity and content of ore components. The conclusion is drawn on homogeneity and the deep nature of carbon.
