Determination of Fine Intergrowth of Low-Fe Epidote and Clinoepidote in the Glaucophane Schist from Mulan Mountain by Electron Probe Microanalysis and Optical Microscopy

摘要: 电子探针和光学显微镜联合分析表明，木兰山蓝片岩中存在斜黝帘石－低铁绿帘石连生体。界面区Fe、Al元素的线扫描曲线研究表明，（Fe,Al)类质同象替代为连生体界面共晶膜的形成机制。木兰山蓝片岩中斜黝帘石－低铁绿帘石连生体的确定，说明电子探针和光学显微镜联合分析可有效确定光学性质和化学成分均相近的微细粒连生体的组成矿物，其结果对认识木兰山蓝片岩的变质演化具有指示意义。
