摘　　要：对云南九顶山斑岩铜钼矿含矿石英脉中的石英流体包裹体分析表明,九顶山铜钼矿成矿流体属于Na Cl-H2O型,均一温度集中在260-320℃,盐度集中在6.50%-10.60%,成矿流体为中低温、中等盐度性质。流体包裹体压力及深度分析显示,成矿流体主要在浅成低压环境下形成,流体演化过程中压力逐渐释放,深度逐渐降低。The ore-forming fluid of the Jiudingshan porphyry Cu-Mo deposits is the NaCl-H20 system based on research of characteristics of the fluid inclusion and the ore-forming is characterized by low temperature and lower salinity. The temperature concentrated between 260 ℃ and 320℃and the salinity concentrated between 6.50% and 10.60%. Pressure and depth analysis shows that ore-forming fluid mainly formed in low pressure shallow-seated environment, and the pressure and depth were gradually reduced with fluid evolution.
