摘要
Abstract
Fluid inclusions in the gold-bearing quartz veins at the Um Rus area are of three types: H2O, H2O-CO2 and CO2 inclusions. H2O inclusions are the most abundant, they include two phases which exhibit low and high homogenization temperatures ranging from 150 to200℃ and 175 to 250℃, respectively. The salinity of aqueous inclusions, based on ice melting, varies between 6.1 and 8 equiv. wt% NaCl. On the other hand, H2O-CO2 fluid inclusions include three phases. Their total homogenization temperatures range from 270 to 325℃,and their salinity, based on clathrate melting, ranges between 0.8 and 3.8 equiv. wt % NaCl.CO2 fluid inclusions homogenize to a liquid phase and exhibit a low density range from 0.52 to0.66 g/cm3. The partial mixing of H2O-CO2 and salt H2O-NaCl fluid inclusions is the main source of fluids from which the other types of inclusions were derived. The gold-bearing quartz veins are believed to be of medium temperature hydrothermal convective origin.关键词
