Ore-forming Π‘onditions of the Blagodat Gold Deposit in the Riphean Metamorphic Rocks of the Yenisey Ridge According to Geochemical and Isotopic Data
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

Minerals of precious metals of nanosize are widespread in gold-sulphidic ore deposits and especially complex deposits. The microβ and nanomineral complex of precious metals in the nepheline rocks of Kuznetsk Ala Tau, which are the ores of aluminous manufacture has been studied. The attention of geologists is paid to large and unique congestion of precious metals in the form of micron and nanosize particles of minerals. Working out of comprehensible technologies of ore-dressing and metallurgical repartition of concentrates is necessary for industrial development of such deposits.

one of the richest gold-bearing world provinces. 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

one of the richest gold-bearing world provinces. 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)
