煤系高岭岩的XRD曲线特征——对高岭石—地开石混层矿物XRD曲线特征的一点看法

XRD patterns of kaolinic rocks in coal measure: different views on characteristics of XRD patterns of kaolinite-dickite mixed-layer mineral

根据高岭石基面衍射是否加强以及加强的程度 ,将我国煤系高岭岩的XRD曲线分为 3种基本形态类型。介绍了 3种XRD曲线的形态特征 ,并分析了造成高岭石XRD曲线差异的原因 ,同时否定了将基面衍射加强的高岭石看作高岭石—地开石混层矿物。

The XRD patterns of kaolinic rocks in the coal measure are divided into three types according to the basal reflection intensity of the kaolinite in China.It is presented the morphological features of the three kinds of the XRD patterns.The reasons by which the differences are caused among the XRD patterns of the kaolinite are analyzed,and it is negated that the kaolinite of which the basal reflections are enhanced is regarded as kaolinite dickite mixed layer mineral.
