摘要
赣南是我国最重要的钨矿产地,漂塘钨矿是赣南的一个重要的大型石英脉型黑钨矿床,含矿石英脉具有多阶段矿化的特征。本文采用"流体包裹体组合"(FIA),这一国际上近年来提出的适用于多阶段流体活动的包裹体研究新方法,对漂塘钨矿主成矿阶段,即黑钨矿—锡石—硫化物—石英脉阶段的含矿石英脉中流体包裹体进行岩相学和显微测温研究,并运用显微激光拉曼光谱测试技术对不同流体包裹体组合(FIA)中单个流体包裹体成分进行测试。结果表明,主成矿阶段具有明显的两期流体活动特征,流体组分主要为水溶液,不含或只含少量的CO_2。
Piaotang tungsten deposit is one of the most important quartz-vein type wolframite deposits in Southern Jiangxi Province where is the most important tungsten producing place in China, The wolframite-bearing quartz veins have the characters of multistage mineralization. ＂Fluid inclusion assemblage＂ （FIA）, which has been successfully applied to the research of multistage fluid activities recently, was adopted to the petrographic and mierothermometrie study on the fluid inclusions in the wolframite-bearing quartz veins from the major mineralizing stage of Piaotang tungsten deposit. The components of the individual inclusions from different FIAs were determined by Raman mierospectroscopy. This study shows that the major tungsten mineralizing process experienced two stages of fluid activities, and that the main component of fluid is H2O with minor or without CO2.
