英文摘要	Gold deposits in the Junggar-Eastern Tianshan of North Xinjiang area, formed in Carboniferous and Permian which completely tallies with the post-collisional time, space and geodynamics background in this area, and represented a result of tectonicmagma-mineralization activity of the post-collision event as well. Fluid inclusion in quartz from the typical gold deposits is characterized by small size, predominant gas-liquid phase, rare daughter-mineral, and containing small and less CO, inclusions, while the ore-forming fluid is low salinity and medium-low temperature. Same deposit type yields similar water-source of ore-forming fluid, whereas different type yields distinct water-source. Characteristics of deep-source S and Pb isotope from ore mineral and REE from pyrite and fluid inclusion prevent a deep-source ore-forming material. The gold element upwards moves in Au-S complex form. The C isotope shows that the carbon of fluid is derived from mixed source by mantle and strata, and that carbon of fluid from the structurally-controlled -altered -dyke type gold deposits occurred in carbonaccous elastic rocks is mainly organic carbon. It is obviously that the biogenic organic carbon derived from sedimentary strata in this area plays an important role on transportation and unloading of deepsource gold.
