Physicochemical Conditions of Ore Formation at the Kalguty Mo–W Deposit: Thermodynamic Modeling

Thermodynamic modeling was carried out for the formation of Mo–W ores at the Kalguty deposit (Gornyi Altai). The modeling was based on the physicochemical conditions of Mo–W ore formation estimated from fluid inclusion data. Quartz–wolframite veins of the deposit were formed under the influence of homogeneous reduced carbonate–chloride fluids, which showed elevated W and Sb concentrations. Pyrite–chalcopyrite–molybdenite mineralization was...
