| 摘 要： | 为了探讨玄武岩铜矿成矿流体的特征,对滇黔交界地区峨眉山玄武岩铜矿3个成矿期次铜矿石中石英和方解石的气液包裹体进行了激光拉曼成分研究和均一温度、盐度测定,对古石油包裹体通过荧光显微镜进行了成分鉴定.结果表明:第1、2期次成矿流体主要为盆地卤水,其气液包裹体气液比小(一般5%～10%),w(NaCl)为8%～22%,气相为...

| Abstract: | In order to understand the characteristics of ore-forming fluids of the Emeishan basalt copper mineralization in adjacent area of northeastern Yunnan and western Guizhou,studies on the composition,homogenization temperature and salinity of the fluid inclusions and palaeo-petroleum inclusions in quartz and calcite of three metallogenic stages have been carried out by means of laser Ramman microprobe,fluorescent microscope and micro-thermometry.The results show that the ore-forming fluids of the first and the... |
