英文摘要Katbasu is a gold (and copper) deposit located in an arc on the southern margin of the Hi-Central Tianshan microcontinent. An in-situ method was conducted to acquire trace element concentrations to elucidate the origins and chemistry of the fluid in the Katbasu deposit. This included oxygen isotopes in quartz, as well as sulfur isotopes and trace elements concentrations in pyrite. Trace elements in gold deficient veins have higher concentrations compared to those in the gold bearing veins. The delta O-18 values of gold deficient veins are between 3.9 and 8.1 parts per thousand, which imply a magmatic oxygen isotope signature. In contrast, oxygen isotopes in gold bearing veins range between -1.3 and 5.8 parts per thousand, indicating the involvement of meteoric water in the mineralization system. This data, combined with evidence from alteration style and metal assemblages, shows that the ore-forming fluids at the Katbasu gold deposit is of a magmatic origin. The data also indicates that meteoric water diluted the magmatic fluid and caused an oversaturation of gold, causing precipitation of native gold grains. Trace elements in pyrite show no difference among the veins analyzed. However, they have distinctly different trace element patterns of pyrite from orogenic gold deposits. Based on the delta S-34 values of pyrite (8.3-12.9 parts per thousand), and the lack of coeval regional metamorphism, we conclude that the enriched S-34 at the Katbasu gold deposit is derived from a subducted slab during the Late Carboniferous.
