| 摘 要： | 通过对X-射线衍射和扫描电镜的黏土资料分析，确定兴安岭群一、二段黏土组合并阐明其分布特征。研究表明兴安岭群兴一段凝灰泥岩或泥岩中有7种黏土组合，在凝灰岩、凝灰质砂岩和砾岩中有7种黏土组合；兴二段凝灰泥岩或泥岩中有6种黏土组合，在凝灰岩、凝灰质砂岩和砾岩中有7种黏土组合。兴一段以伊利石和绿泥石高含量、兴二段以高岭石、伊利石高含量为其特征。

| Abstract: | Using X-ray diffraction analysis and SEM observation,the clay complexes and their characteristics of members 1 and 2 of Xing'anling Group are determined and the distribution characteristics of clay minerals in space are interpreted. The research shows that in Member 1 of Xing'anling Group the tuffaceous mudstone or mudstone has seven types of clay complex;and tuffaceous sandstone and conglomerate has seven types of complex. The tuffaceous mudstone or mudstone in Member 2 has six types of clay complex and the tuff,tuffaceous sandstone and conglomerate have seven types of complex. In plane distribution,the contents of the chilkinite and chlorite in the Member 1 are higher than those of other clay minerals. The contents of kaolinite and chilkinite in the Member 2 are higher than those of others. |
