摘要
产于甘肃山丹平坡矿区太原组中段顶三槽煤层夹矸中的I/S混层矿物为IS型有序混层。它主要由Na-Ca或Ca-Na型蒙皂石层和似2M_1型伊利石层组成。混层矿物的原始物质主要为火山凝灰质,并且形成于蒙皂石向伊利石的成岩转化过程中。
Illite/Smectite mixed-layer minerals in clayrock band between Dingcao and Sancao coalbeds of Taiyuan Formation in Pingpuo Mine Area of Shandan County, Gansou Province are IS-ordered mainly made up of Na-Ca or Ca-Na type smectite layers and 2M_1 polytype illite layers. The original material is princiaplly volcanic tuff, formel in the process of transformation of smectite to illite.
