    Neodymium and strontium isotopic composition and rare earth elements (REE) distribution pattern have been determined in whole rocks and minerals were separated from host metamorphic rocks and disseminated sulfide ores of the Blagodat gold deposit. Isotopic data are given to construct few isochrones that could be reflected an age of main stages of metamorphic and metasomatic alteration in rocks varieties during a successive accumulation of gold in structural traps. The significant temporal range in the forming of the studied rocks can be interpreted as an evidence of multi-stage tectonic destruction accompanying with trust-folding processes, shear deformations and development of local fracture zones that had place from the Late Riphean to Middle Paleozoic time. According to isotopic data basic ore-forming processes were realized in the relatively narrow interval from 690 to 750 Ma that correspond to a beginning of continental rifting on the western margin of Siberian craton. Chemistry and trace element distribution are closed for host and auriferous schists and mainly showed differences in the composition initial sedimentary units. The middle negative value Ξ΅Nd (from -14 to -16) and very high positive value Ξ΅Sr (from +570 to +725) are mostly corresponded to that of upper continental crust matter. The role of synchronic granite intrusions in the studied area can be only estimated due to a generation of thermal energy and crustal fluids

Prevailing confideness of gold-bearing projects to the Korda and the Uderey Riphean suites is revealed on the basis of statistical analysis. Deposits are developed in folding and fault metamorphism zones in the area of flexure bending of Riphean strata by intruding granitoid masses. Ore-bearing hydrotherms are genetically associated with ultramorphism and granite formation zones. The main types of structures of ore fields are folding zones: in S-shaped disjunctive faults at the limbs of line anticlines; complicating the limbs of compensational synclines in contacts with granitoids; in the contact area (non-conformity) of Lower Proterozoic and Riphean strata; in trough sedimentation basins. Nepheline intrusions take a specific position in gold-bearing occurrences of the Yenisey Ridge. Their commercial value requires study. The age of gold mineralization of the Yenisey Ridge corresponds to the range of 847-605 MA. In some deposits there probably was a stage of re-distribution of gold-ore mineralization during the Devonian Age (364-368 MA)

Prevailing confideness of gold-bearing projects to the Korda and the Uderey Riphean suites is revealed on the basis of statistical analysis. Deposits are developed in folding and fault metamorphism zones in the area of flexure bending of Riphean strata by intruding granitoid masses. Ore-bearing hydrotherms are genetically associated with ultramorphism and granite formation zones. The main types of structures of ore fields are folding zones: in S-shaped disjunctive faults at the limbs of line anticlines; complicating the limbs of compensational synclines in contacts with granitoids; in the contact area (non-conformity) of Lower Proterozoic and Riphean strata; in trough sedimentation basins. Nepheline intrusions take a specific position in gold-bearing occurrences of the Yenisey Ridge. Their commercial value requires study. The age of gold mineralization of the Yenisey Ridge corresponds to the range of 847-605 MA. In some deposits there probably was a stage of re-distribution of gold-ore mineralization during the Devonian Age (364-368 MA)
