| 摘 要： | 本文在对塔山煤矿的矿井概况和区域构造背景介绍的基础上，阐明了塔山煤矿煤系地层粘土资源的分布特征，对形成粘土岩的物质来源和成因类型进行了探讨，指明了塔山煤矿煤系地层中的粘土矿物主要是以沉积作用为主的高岭石粘土岩，其次是火山喷出物质在水介质中经蚀变作用和风化残积物在海水碱性介质中，由于地球化学分凝作用再沉积而成，最后总结了塔山煤矿主要粘土矿物——高岭石的形成条件。

| Abstract: | A brief introduction has made to Tashan coalmine general situation and tectonic setting. Expounded coal measures strata clay resource distribution features, discussed claystone mass origin and genesis. Pointed out clay minerals in coal measures strata are mainly deposited kaolinitic claystone, secondly volcanic ejecta altered and weathering residual in water media and sea water alkaline media then resedimented through geochemical segregation. |
