英文摘要The Cu-Mo mineralization of Xilekuduke porphyry Cu-Mo deposits in northern Junggar is related with veins of andesite porphyrite and dacite porphyrite. The alterations include K-feldspar alteration, sericitization, epidotization, the chlorite is developed outward and skarnization is developed in the deep. Mo mineralizations dominate in the shallow and Cu-Mo mineralizations in the deep. Quartz veins from Xilekuduke porphyry Cu-Mo deposit contain fewer fluid inclusions in quantity and smaller in size, also fewer gas inclusions and more CO, gas inclusions and daughter mineral inclusions than the typical porphyry Cu-Mo deposits. Further more, the daughter minerals in Xilekuduke porphyry Cu-Mo deposits mainly are NaCl but not KCl. There occur more boiling CO(2)-rich fluids in the molybdenum-rich region, but more inclusions bearing big daughter minerals without any boiling inclusions in the chalcopyrite-concentrated region. The mineralization of molybdenum chiefly related with the boiling of CO(2)-rich fluids, porphyry alteration and skarn alteration. Molybdenum mainly originates from the crust, and copper is mainly related with the high-salinity magmatic fluid that directly exsoluted from the melting of basic magma and skarn alteration, it chiefly originates from the upper mantle. The mineralization temperature ranges of molybdenum is from 280 to 530 degrees C, mostly between 300 similar to 400 degrees C. The late mineralization temperature is between 180 similar to 300 degrees C, and that of copper mineralization is below 350 degrees C. The characteristics of the ore-forming fluid reflect the features of the fluid mixing between the crust source and the mantle source and the mixing of magmatic hydrothermal fluids and the meteoric water.
