为探讨西华山钨矿床流体的稀土元素和微量元素特征，明确热液和成矿物质的来源，揭示成矿流体性质，采用高精度电感耦合等离子质谱（ICP-MS）方法对该矿石英脉流体包裹体的微量和稀土元素进行了分析测试。结果表明，流体包裹体中稀土元素总量变化大，主要表现为轻稀土富集，轻、重稀土内部分异程度不均一，轻稀土分馏程度明显大于重稀土分馏程度；δEu变化范围比较大，大部分样品表现为δEu的负异常；微量元素之间的比值反映出西华山钨矿床成矿物质从深源到浅源，主要来源于岩浆，同时又有少部分来源于大气水循环作用淋滤围岩地层所产生的矿物质，成矿流体处于流体演化的晚期热液低温阶段。

The paper analyzes and tests the inclusions in quartz of REE and trace elements by using ICP-MS for showing hydrothermal and ore-forming materials and understanding REE and trace elements characteristics of the fluid inclusions of Xihuashan Tungsten Deposit. REE in fluid inclusions changes, mainly for LREE enrichment, light and heavy rare earths vary within some degree of heterogeneity, significantly greater than the degree of LREE HREE fractionation fractionation;δEu range is relatively large, the majority of samples performanceδEu negative anomaly;trace reflects the ratio between the tungsten deposit into Xihuashan minerals from deep to shallow, mainly from magma, while there are a small part of the water cycle from the role of atmospheric leaching of the rock strata produced minerals, ore-forming fluids in low-temperature hydrothermal fluid evolution in advanced stages.
