The ore specialization of carbonatite complexes of Urals-Timan region has been established: niobium and rare earth-niobium - for the Urals’ carbonatite complexes, the rare-earth - for carbonatites of Timan. The carbonatites of Il'menо-Vishnevogorsky miaskite-carbonatite complex (Urals) are a type of industrial niobium deposits (pyrochlore type of ores). The carbonatites of Baiksky ultrabasic complex (The Urals) are rare earth-niobium type deposits (monazite-aeschynite-columbite-pyrochlore type of ores). The carbonatites of Chetlassky complex (Middle Timan) are cerium type deposits of bastnesite carbonatites (with monazite-bastnesite type of ores). The picrite-lamprophire series of Chetlassky complex have diamond prospects. The ore specialization of the Urals and Timan carbonatite complexes are determined by their formational affiliation.

The data on C, O, Sr and S isotope composition of the carbonates, quartz and sulfides from the Tamunier and Vorontsovsk gold-ore deposits, localized in the Auerbakh volcano-plutonic belt are cited. It is established that on mineral isotope characteristics the nearest analogue of mineralization in beresites of the Tamunier deposit is the gold-polymetallic mineralization in jasperoids of the Vorontsovsk deposit. Calculation of the C, O and S isotope composition of the ore-bearing fluid testifies to a participation in ore-formation of two main substance reservoirs - the rock (sea carbonates and biogenic pyrite of host volcanogenic-sedimented series) and the fluid one (metalliferous magmatogene, as well as metamorphogenic fluids connected by the intrusive mass injection).
