The monograph presents the results of a study of cobalt-copper-pyrite deposits associated with ultramafic rocks, using the example of paleoisland-arc structures in the Urals. The heterogeneity of deposits is determined by: 1) two-stage formation of mineralization associated with different geodynamic regimes; 2) the formation of ores in various ways - hydrothermal-sedimentary, sedimentation and hydrothermal-metasomatic. For the first time, monoclinic Co-sulfoarsenide - alloclasite, Co-Ni-Fc-diarsenides: lellingite, saf-florite, rammelsbergite and krutovite, as well as the distribution and forms of gold precipitation, which is closely associated with sulfoarsenides and arsenides of cobalt, nickel and gland. A comparative analysis of ancient and modern cobalt-containing pyrite ores from ultramafic rocks has been carried out. The conclusion is made about the possibility of revealing sulfide ores in ultramafic sheets of accretionary prisms of modern island arcs. For specialists in the field of ore geology and mineralogy, graduate students and students.
