英文摘要	The dating of fluid inclusions of quartz yields an Ar-Ar isochrone age of 320.4+/-6 Ma. Three types of fluid inclusions have been identified with the homogenization temperature ranging from 157degreesC to 362degreesC. The homogenization temperature consists of two groups. The first group varies from 157degreesC to 166degreesC, and the second from 232degreesC to 362degreesC. Their chemical composition is dominated by Na+-Ca2+-Mg2+ and Cl-. The relative concentration of ions is characteristic by Na+>Ca2+>K+>Mg2+ and Cl->SO42-->F-. The deltaD and delta(18)O values indicate that the ore-forming fluid originates from mixing of multi-source water. The Sarkobu gold deposit has experienced two mineralization stages: gold was enriched during the volcanic-exhalative-sedimentary process in the early stage, while the gold deposit was finally formed under compression-shearing during the orogenic period.
