| 英文摘要 | Sanjia gold deposit is a typical lode gold deposit in the Muping-Rushan gold belt of Jiaodong Peninsula, eastern China. Gold occurs mainly in pyrite- and polymetallic sulfide-quartz vein/veinlet stockworks. Fluid inclusions in the altered wallrocks and gold ores show CO(2)-H(2)O-NaCl fluids of three main types, namely H(2)O-CO(2), CO(2)-rich and aqueous inclusion. Early milk white quartz contains original H(2)O-CO(2) inclusions. In the pyrite quartz vein and polymetallic-sulphide quartz vein, CO(2)-rich inclusions occur in isolation or cluster with large range of H(2)O/CO(2), whereas the aqueous inclusions occur as secondary trails in microfractures cutting earlier quartz grains. On occasion CO(2)-rich inclusions with variable aqueous phase were co-occurrence within the same clusters, and mostly homogenize to liquid or vapor at the same temperatures, indicating immiscibility did occur at the deposit. Quartz and calcite in the late ore-forming stage developed original aqueous inclusion. Microthermometric data show the homogenization temperatures of the CO(2)-H(2)O inclusions in the early ore-stage fall in the range between 280 and 416 degrees C. Homogenization temperatures, obtained mainly from CO(2)-rich inclusions with relatively small CO(2) bubbles in the main ore-stages, range from 210 to 330 degrees C. Homogenization temperatures of H(2)O aqueous inclusions at same stage with CO(2)-rich inclusions are between 253 and 377 degrees C, Homogenization temperatures (to liquid) of the aqueous inclusions in the late stage range from 176 to 207 degrees C. Fluid immiscibility caused by change of mineralizing stress possibly led to the gold precipitation at Sanjia. |
