摘　　要：应用化学分析、扫描电镜、X射线衍射等多种手段,对绿泥石-蒙皂石间层矿物进行了分析研究。塔里木盆地存在含绿泥石-蒙皂石间层、不含高岭石和含绿泥石-蒙皂石间层、含高岭石两种基本类型的矿物组合,前者主要见于上第三系—白垩系及石炭系个别层段,后者主要分布于白垩系个别地区。两类矿物组合形成条件有所差异。Interstratified chlorite-smectite minerals in Tarim basin are studied by means of chemical analysis,SEM,X-ray diffraction,etc.There exist two basic minerals combinations of interstratified chlorite-smectite without kaolinite and interstratified chlo rite-smectite with kaolinite.The former is mainly found in several strata or intervals of Neogene-Cretaceous and Carboniferous;the latter is dis-tributed in individual zone of Cretaceous.The forming conditions of these combinations are slightly different from each other.
