| 摘 要： | 赣南西华山钨矿床是一个闻名中外的大型石英脉型钨矿床。为探讨成矿流体性质以及演化过程,本文对西华山石英脉型钨矿床主成矿阶段含矿石英脉中流体包裹体进行了岩相学、显微测温学研究和激光拉曼光谱分析。结果显示,西华山钨矿床的流体包裹体以H2O-NaCl型为主,局部发育H2O-NaCl-CO2型。流体热焓-盐度图解表明成矿流体以混合作用为主,局部沸腾在热液系统演化中作用不大。通过对沸腾包裹体的测温数据进行计算,得出西华山脉型钨矿成矿压力约为27～87 MPa,矿床形成深度约为1.0～3.3 km。

| Abstract: | Xihuashan tungsten deposit is a famous large quartz-vine type wolframite deposit in Southern Jiangxi Province,China.To investigate the characters and evolution of ore-forming fluid,the fluid inclusions associated with the wolframite-bearing quartz veins were investigated by using microthermometry and the Raman microprobe.The fluid inclusions are mainly liquid-rich aqueous inclusion(H2O-NaCl type) and H2O-CO2-NaCl inclusions are found in 538 level of mining.Enthalpy-salinity plot indicates that mixing appear... |
