These are sections with numerous geochemical anomalies and ore occurrences of Mo, U, V, Zn, Cu, Au, Ag being confined to. In the of Krivoy Rog zone carbonaceous rocks are present at the different levels of the section of the krivorizhskaya series. The thickest sections of carbonaceous rocks are typical for the upper - the gdantsevskaya - suite. The of graphit contents reach 2-8% but in local sites carbonaceous schists contain up to 30-40% of graphite. The highest of Cu, Zn, Au, Ag, concentrations often with is noticed in the areas of supply of deep carbon-bearing fluids. А carbon-rich rocks, ассогding to its main isotope-geochemical data similar of Кarelian shungites, was discovered in the Мlуinkivski part of within schist rocks of gdantsivska suite. Intensely tectonized carbonaceous rocks and spatially conjugated with them sulphide-quartz-argillizite metasomatites have brightly manifested geochemical speciation with high geochemical background of Au, (Pt, Pd). Considerable elevation of Cu, Pb, Zn, Ag, Au concentrations have bееn fixed in the zones of tectonic-metasomatic transformations of graphite-containing rocks manifestations of shungite-like rocks (?13С is up to -35‰), and dolomite horizons (?13С is up to +12,8‰) are specific. is noticed in the areas of supply of deep carbon-bearing fluids. The conclusion about necessity of detailed study the ore manifestation on the "contact K2 - K3" type is proposed. Researches in non-traditional useful minerals will make it possible to increase of Krivoy Rog region.5481 Product Description popup.authors Возняк Дмитро Костянтинович Мельников Вололдимир Степанович Пономаренко Олександр Миколайович Юшин Олександр Олександрович popup.nrat_date 2020-04-02 Close
