| 英文摘要 | Miansawa gold deposit is located in the west margin of the Yangtze craton, at the eastern margin of the Tibetan. The gold deposit occurs in the mylonitic granite and (or) plagiaplite, controlled by NNE-trending ductile-brittle ductile shear zone. The gold mineralization occurs mainly as auriferous quartz veins with minor sulfide minerals. Fluid inclusions in pyrite have He-3/(4) He ratios of 0.69 to 0.82 Ra, whereas their Ar-40/Ar-36 ratios range from 251 to 509. The He and Ar isotope data indicate mixing of fluids of mantle and crustal origin. The delta(34)S values of pyrite are from - 1.8 to 2.2 parts per thousand, with an average of 0.5 parts per thousand, suggesting a mantle source. Hydrothermal quartz has delta(18)O values between - 2.5 and 0.7 parts per thousand and deltaD values between - 64 and - 93 parts per thousand, indicating mixing of magmatic and meteoric fluids. The paper concludes that the noble gas isotopic data, along with the stable isotopic data suggest that the ore-forming fluids is a mixture between mantle-derived fluids and meteoric water, the gold mineralization are the results of the collision between India plate and Asia plate, associated with sklip-slip faults in the Oligocene. |
