Аннотация: The results of the study of mineral indicators of productive parageneses and composition of metal-bearing fluids from arsenide-cobalt deposits of the Bou-Offro - El-Graara (Moroc) ore belt are presented. The applied comprehensive approach to solving this problem, namely, the study of the macro- and microcomponent composition of solПоказать полностьюutions and the gas phase of the fluid, using both classical (thermo and cryometry) and modern accurate quantitative methods (LA-ICP-MS and KR-spectroscopy) involving determination of the isotopic composition of fluid inclusions solutions allowed us to substantiate at a qualitatively new level the polygenicity of substance sources and solutions in the formation of cobalt hydrothermal deposits proper.The results obtained served as the basis for thermodynamic modeling of the conditions of joint transport and deposition of Co, Ni, Cu, Fe, Mg, Ca, Ag, Au, Bi, U, Pt and Pd. Physical and chemical factors of the deposition of native metals: gold, silver, platinum and palladium in the ores of such deposits are revealed. In Ni-Co-As deposits, noble metals were deposited either together with nickel and cobalt arsenides, forming close intergrowths, or as part of mineral parageneses associated with the manifestation of later hydrothermal processes that were substantially separated in time from the stage of formation of cobalt arsenide ores.
