在山西省境内,高岭石质粘土岩以夹层粘土产于上石炭统太原组煤系地层中,该岩石在煤系中广泛分布。作者对怀仁县和山阴县某些地区的高岭石质粘土岩样品进行了研究,发现某些高岭石质粘土岩主要由粗粒矿物组成。应用各种方法测定的结果认为,它们不是高岭石,而是一种高岭石-地开石混层矿物。 In Shanxi Province, kaolinite stratum clay is produced by interlayer clay in the coal measure strata of the Upper Carboniferous Taiyuan Formation, which is widely distributed in coal measures. The authors studied kaolinite stony clay samples in Huairen County and some parts of Sanyin County and found that some kaolinite clay rocks are mainly composed of coarse-grained minerals. The results of various methods of determination suggest that they are not kaolinite but rather a kaolinite-dickite mixed mineral.
