Abstract The results of studying fluid inclusions in the quartz of ore body no. 6 from the Sovinoye deposit developed by the underground mine workings at a depth of 80 m from the surface are considered. The investigations showed that the ore in the Sovinoye deposit was formed at average temperatures during several stages from weakly concentrated hydrotherms saturated with Na, Cl, Mg, and Fe ions. Such ore-forming conditions are typical of mezothermal gold-quartz veined deposits in the terrigeneous quartz-carbonate strata. The results of FI study by modern methods do not contradict the previously offered metamorphogenic-magmatogenic model of ore formation for the Sovinoye deposit. Ausführliche Beschreibung
