英文摘要 | The Hongyuan Mo deposit is a newly discovered porphyry-type deposit in the West Junggar region, Xinjiang, which occurs fine vein and disseminated mineralization. Main ore mineral is molybdenite, followed by chalcopyrite and pyrite. It develops hydrothermal alteration. Based on fluid inclusion studies, we find it different from typical porphyry Mo deposit, with the existence of CH, in ore-forming fluid, belonging to NaCl-H2O-CO2-CH4 fluid system. Geochemical data of biotite shows a slightly high oxygen fugacity in the granite crystallization stage. The C isotope data of CH, in ore-forming fluid is ranging from -31. 08 parts per thousand to - 26.44 parts per thousand, indicating the source of crustal organic carbon. Stage I, the early stage of mineralization, the homogenization temperature mainly is 340 similar to 360 degrees C, with high temperature-high salinity and low salinity fluids, weakly reduced fluid, Mo, Cu and other metal minerals are enriched in fluid, with little Mo, Cu mineralization, developing muscovite alteration at high temperature. Stage If, the main stage of mineralization, the homogenization temperature mainly is 280 similar to 300 degrees C, low salinity, the combined action of boiling, atmospheric water and reducing environment causes a large amount of precipitation of Mo, Cu and other metal minerals, forming the main ore body, with sericitization alteration. Stage III, the late-mineralization stage, the homogenization temperature mainly is 160 similar to 180 degrees C, fluid changes to low temperature and low salinity, with weakened mineralization and carbonatization alteration of wall rock. |
