摘　　要：通过对南票煤田晚古生代沉积层中的火山角砾和沉凝灰岩X射线衍射分析及对比 ,确定在火山碎屑岩中有高温矿物透长石的存在 ;结合差热分析确定粘土矿物主要为蒙脱石和高岭石。According to x ray diffraction analysis and correlation on volcanic breccia and tuffite of late Paleozoic deposits from Nanpiao coil field, the high temperature mineral sanidine of pyroclast rocks are determined, and by combining with the differential thermal analysis, the main clay minerals montmorillonite and Kaolinite are ascertained. The results play an important part in studing and further investigation of volcanic event layers from this area.
