| 英文摘要 | The saridala gold deposit, xinjiang uygur autonomous region, is located in the east of west tianshan, the north of the middle tianshan axis. it is a medium sized gold deposit in the wangfeng gold belt and its host rocks are the precambrian sericite quartz phyllonite and early paleozoic granitoid. the saridala gold deposit is obviously controlled by the shenlidaban ductile shear zone showing hydrothermal alteration of pyritization, sericitization, silicification, albitization and carbonation. the vein crosscutting relationships and mineral replacement suggest that the ore forming process includes the early, middle and late stages. in the quartz of saridala gold deposit, four types of fluid inclusions (fis) are identified as co(3)-h(2)o (c-type), pure co(2) (pc-type), aqueous water (w-type) and daughter mineral-bearing (s-type). the early-stage quartz contains primary c-type fis with homogenization temperatures of 301.0 similar to 491. 4 degrees c. the middle-stage quartz trapped all the four types of fis, of them the c-type fis account for the majority. the c-type fis, composed of co(2) + h(2)o +/- n(2), have the salinity of 0.43% similar to 10. 91% nacleqv. and homogenization temperatures of 255.8 similar to 475. 0 degrees c. trapping pressure in middle stage estimated from the c-type fi ranges 115. 1 similar to 307. 5mpa, corresponding mineralization depth of about 11km. the late-stage quartz contains only the w-type fis with the salinity of 1. 32% similar to 15. 58% nacleqv. and the homogenization temperatures of 146.2 similar to 254. 6 degrees c. therefore, the ore fluids in the early and middle stages are characterized by meso- to hypothermal, co(2)-rich and low salinity, which are considered as the nature of metamorphic fluids, whereas the late-stage fluids are low temperature, low salinity and co(3)-poor. depressurized fluid-boiling or phase separation caused gold precipitation in the middle-stage. the saridala gold deposit is a meso-to hypozonal orogenic gold deposit. |
