Abstract
The analysis of the gas phase composition of fluid inclusions in quartz from Krasnoye gold deposit (Eastern Siberia) was carried out using Horiba LabRam HR800 Evolution Raman spectrometer. CO2 was found to be the major component of fluid inclusions in quartz; it is formed due to fluid-rock interaction during the destruction of host black shales. CO2 mol fraction (and CO2 density) in inclusions in quartz from the gold-bearing and barren vein were estimated as 96.9–98.6 and 88.3–98.0% mol (1.23–1.29 and 1.25–1.30 g/cm3), respectively. No differences in CO2 and N2 concentrations were found between the gold-bearing and barren quartz veins. The calculation results of the gas phase composition have been confirmed by gas chromatography. Based on our experience, study the composition of fluid inclusions which size is in the range 5–40 μm and located at the depth of about 100 μm from the surface of transparent minerals is promising when using HR800 Raman spectrometer.
