英文摘要	The Hongshi gold deposit is one of typical deposits from the Kanggurtag gold belt in the Eastern Tianshan, Xinjiang, NW China. Fluid inclusion and H, O, C, and S stable isotopic studies on the deposit have been carried out in this paper. The obtained data from fluid inclusion study indicate that the ore-forming fluids are rich in CO2 and characterized by middle-low temperature, low salinity, and middle-low density. Concurrently, hydrogen (delta D-SMOW = -104 parts per thousand similar to -63 parts per thousand) and oxygen (delta O-18 = -13.8 parts per thousand similar to 15.5 parts per thousand, delta O-18 = - 1. 7 parts per thousand similar to 6. 1 parts per thousand) isotopic compositions of quartz, and carbon (delta C-13(PDB) = - 3. 5 parts per thousand similar to - 2. 7 parts per thousand) and oxygen (delta(18) O-PDB = -28.9 parts per thousand similar to -26.5 parts per thousand delta 18O(SMOW) = 1. 1 parts per thousand -3.5 parts per thousand) isotopic compositions of calcite indicate that the ore-forming fluids are derived from the both the deep fluid and the magmatic fluid, and mixed with meteoric water at last stage. Sulfur isotopes of pyrite range -11.5 parts per thousand similar to 3. 8 parts per thousand with average value of 1. 73 parts per thousand, implying the sulfur of ore-forming materials is characterized by deep-seated sulfur similar to that of meteorite. Briefly, the mineralization process of the Hongshi gold deposit can be summarized as follows In the regional shearing regime, the deep fluids rich in metallogenic elements flow upward inside the shear system, and mixed eventually with the shallow fluids, and experience the replacement with country rocks. Finally, metallogenic elements concentrate and deposit within the shear zone due to the change of physical-chemical conditions in the shallow level.
