摘　　要：本文叙述了贵州大方伊 /蒙不规则间层粘土 (I/S)的矿物学特征 ,包括矿物组成、化学成分、谱学特征、显微形貌特征以及理化特征 ,并对其应用前景进行了探讨。结合XRD和HRTEM两方面证据 ,获得了关于该矿物在C轴方向上的堆垛方式 ,三种以上共存的间层作用类型有力地证实了其不规则性。This paper respectively describes the mineral and chemical composition, the characteristics of X ray diffraction (XRD), Fourier transform infrared spectrometric (FTIR), thermal analyses and micro morphological characteristics (by PM, SEM and HRTEM) for the mixed layer illite/smectite from Dafang, Guizhou. It is observed that there are more than three kinds of interstratifications or stacking sequences between the mica layer and the smectite layer in the direction of axis C, proved by XRD indirectly and by HRTEM directly. The good properties in ion exchanging, absorption and acidity, will make it applicable as catalyst and absorbent.
