| 英文摘要 | Kuoerzhenkuola gold deposit, located in calc-alkaline volcanic rock in Hercynian island arc, in northwest of Xinjiang, is volcanogenic late-stage hydrothermal ore deposit. The study of fluid inclusions indicates that inclusions in mineralizating early-stage are gaseous inclusions. The homogenization temperature ranges between 308 C and 396 C and The salinity is from 5.86 to 8.41wt% NaCl. The mineralizating major- stage (II, III) is gas-liquid inclusion. The homogenization temperature is 209degreesC similar to 276degreesC (II) and 148 similar to 180 degreesC (III) respectioely, and the salinity is 5.11 similar to 7.86wt% NaCl (II) 2.74 similar to 6.17wt% NaCl (III), respectioely. Composition of fluid inclusions in quartz is measured relatively according to different mineralizating stage, in order to rule out the influence of coexisting inclusions in different mineralizating stage. The result indicates that ore-forming fluid is a type of Na+ - HS- - Cl- - H2O fluid with medium-low temperature and low salinity. Au is transported by the type of auric-sulfur complex and the ore is formed in reduction condition. Hydrogen and oxygen isotopes of fluid inclusions in the mineralizating major- stage are -83.97 similar to89.07 and 1.8 similar to3.2, respectively, and show that the solutions were mainly originated from magmatic water and meteoric water. The fluid mixing and water-rock reaction have caused the deposition of Au. |
