中文摘要：

云南罗平富乐铅锌矿是川滇黔铅锌成矿域内赋矿层位最新的大型铅锌矿床,成矿流体研究薄弱,铅锌成矿作用过程的认识缺少实际地球化学依据。对该矿床及邻近矿点中闪锌矿流体包裹体的研究表明,该区矿床（点）闪锌矿中流体包裹体以气液相包裹体为主,其次为含子矿物多相包裹体,显微测温获得闪锌矿流体包裹体均一温度主要分布在120~160℃和180~210℃两个区间,盐度分布在4%~10%和16%~22%两个区间,矿区存在低温和中温两类成矿流体,该类流体属于少量油田水混入的Na~＋-Mg~（2＋）-SO_4~（2-）-Cl~-型流体,结合富乐矿区矿体及矿石组构特征分析,该区成矿流体具有低温和中温流体混合特征,在成矿流体混合部位形成富厚矿体。该成果为认识该区铅锌成矿作用提供了新的地球化学证据。

英文摘要：

This paper focuses on sphalerite-hosted fluid inclusions from Fule lead-zinc deposit and outskirts in Luoping County; liquid-vapors fluid inclusions are the main types for the microscopic observation. Ore-forming fluid is mixed with little oil-field water, and is beating Na＋-Mg2＋-SO42-Cl- fluids. The homogenization temperature is mainly in the ranges of 120-160 ℃ and 180-210 ℃; the salinity has two peaks at low salinity（ 4%-10% NaCleq ） and high salinity（ 16%-22% NaCleq）. Those results reflect that mining area has a mixture of medium- and low-temperature fluid. Combining the characteristic of the ore-body and fabric of minerals, two types of the ore-forming fluids are forming rich ore-body by mixture action. Results provide new geochemical evidence for understanding lead-zinc mineralization in the area.
