英文摘要	The Xiadeboli Cu-Mo deposit is a newly discovered porphyry deposit in the southern of Eastern Kunlun tectonic belt, Qinghai Province. We will describe the basic geological futures of the deposit in this paper and study the geochronology, geochemistry character of the porphyry granite and the fluid character of the deposits. The results of zircon SIMS U-Pb of the granite porphyry in Xiadeboli ore district indicate an age of 244. 2 +/- 2. 1 Ma. The porphyry granite is characterized by high SiO2 (72. 00% similar to 74. 92%), Al2O3 (13. 60% similar to 14. 52%) and low K2O (1.86% similar to 1. 72%) contents, belonging to the clac-alkaline series, while the trace elements of the porphyry granite show LREE ((La/Yb)(N) = 11. 83 similar to 5. 64) enrichment, LILE enrichment and HFSE depletion. The main type of the fluid inclusions in the quartz is liquid fluid inclusion while there are also some daughter salt-bearing inclusions and vapor-riched inclusions. The homogenization temperature of fluid inclusions in quartz related to mineralization ranges from 250 similar to 310 degrees C while salinity ranges from 2.77% similar to 32. 27% NaCleqv. There are several reasons for the precipitation in Xiadeboli district, but the most important one among which may be the change of the chemistry/physical condition caused by fugacity gas escaping from the parent fluid during the process of the fluid immiscible.
