摘要
本文采用多种电子显微技术 ,研究了内蒙古大青山煤田晚古生代巨厚煤层夹矸隐晶质高岭石泥岩。透射电镜下 ,晶化程度不一、形态复杂多变的玻屑状高岭石和盘旋状埃洛石 ;扫描电镜下 ,泥粒状高岭石和蠕虫状高岭石以及二者所构成的斑状结构等许多具成因意义的微米级 (0 .1～ 10 μm )显微特征 ,充分证明该夹矸层为火山灰蚀变成因 (tonstein)。
By means of electron microscope the authors have studied a dirt band in a mega\|thick coalseam from the Daqingshan coalfield (Late Paleozoic), Inner Mongolia. The dirt band is a cryptocrystalline kaolinite mudstone. Glassy kaolinites and whirling allokites have been observed under a transmission electron microscope; pisolitic kaolinite, worm\|like kaolinite and the porphyritic texture made up of the two under a scanning electron microscope. These microscopic characters have fully proved that the dirt band is of ash\|altered origin, i.e., tonstein.
