چکیده انگلیسی
Pyrite from the Jintingling deposit has δ34S values (5.5â°-6.1â°) similar to those of pyrite from other gold deposits in the Jiaodong district, indicating that they were related to the same hydrothermal ore-forming system. The δ13CPDB values of calcite (â4.5â° to â5.4â°) in V5 are generally located in the range of magmatic-derived carbon. Fluids of V2, V3, V4 have δD from â64.4â° to â87.1â°, and δ18O from 8.4â° to 0.2â°, located in the compositional fields between magmatic water and meteoric water. Collectively, microthermonetric results and isotopic data indicate that the primary ore-forming fluids were most probably magmatic in origin, with incorporation of meteoric water in the later ore-forming stage. Precipitation of gold was triggered by cooling of fluids, fluid immiscibility and decrease of sulfur in the fluids.
