我国各地膨润土的矿物学性质

Mineralogical Properties of Various Bentonites in China

摘要: 运用X射线衍射分析技术对我国不同产地膨润土的矿物学性质进行考察；利用K值法测蒙脱石含量。实验表明，各地膨润土具有蒙脱石的含量较高且均为二八面体的矿物学特点；可能由于所处的矿层或局部地球化学环境不同，使得相同矿床的不同颜色膨润土矿物的蒙脱石含量有所差异。

Abstract: X ray diffraction analysis method was used to investigate the mineralogical properties of bentonites from different regions of China. The contents of montmorillonite in bentonites were determined by K value method. The results show that the contents of
