摘　　要：大方庆阳煤矿区龙潭煤系和茅口灰岩界限粘土岩分析结果表明:该层粘土岩为黄铁矿质高岭石粘土岩,对其化学成分中Na2O、K2O、MgO、CaO和Pb的研究认为,该层粘土岩是在安静低能、酸性介质还原环境下,为受峨眉山玄武岩影响的火山事件沉积粘土岩。The claystone between the Longtan coal series and the Maokou limestone in the Dafang region, Guizhou is characterized by higher TiO2 and Pb, low MgO and CaO which suggests it was formed under reducing conditions related to the Emeishan basalt eruption.
