ABSTRACT
The features of geological structure and regularity of endogenous deposits location are studied where mineral paragenesis of productive stages are represented by cobalt arsenides, nickel and iron arsenides, as well as associate sulfoarsenides, sulphosalts and sulfides of chalco- and siderophile elements, native metals - silver, bismuth, gold and arsenic, in some cases by pitchblende mineralization. Cobalt manifestations on the mentioned territory are mainly referred to [3-4] two genetic types: hydrothermal and less popular contact-metasomatic. The first of these types is represented by nickel-cobalt arsenide, copper-cobalt sulfoarsenide, cobalt-copper sulfoarsenidefahlore and bismuth-sulphosalt cobalt-bearing vein ore formations, and the second – cobalt-sulfoarsenide skarn, sulfoarsenide-magnetite cobalt-bearing scarn and sulfoarsenide cobalt-bearing listvenite-beresite ore formations. Cobalt ore deposits are usually limited to interblock zones locking activated areas of deep faults, or to splits of confirmed blocks basement. Therefore abundant arsenide nickel-cobalt ores are of some industrial interest, they are concentrated in ore clusters and intersection areas of zones of deep and large regional faults with a huge history of geological development, complex and differentiated intrusive magmatism and intense hydrothermal-metasomatic transformations.
