Аннотация:In this paper, we determine the PTX parameters of the fluids that formed the Olimpiada gold–sulfide deposit using microthermometry and Raman spectroscopy of carbonic (CO2-N2-CH4) and aqueous-carbonic inclusions in quartz. Low-gold-bearing metamorphogenic pyrrhotite–quartz veinlets were formed with the participation of oxidized (CO2/CH4 = 10–100) nitrogen–carbon-dioxide fluid at 410–360°C and 2.4 ± 0.2kbar. Gold–arsenopyrite mineralization was formed by deep reduced (CO2/CH4∼1)methane–carbon-dioxide–nitrogen fluid in the temperature range of 360–300°C at 1.2 ± 0.1 kbar while gold–antimonite mineralization was formed by nitrogen–methane fluid at 290–240°C and 0.8 ± 0.1 kbar. Gold transport was carried out in a boiling environment in carbonic phase.
