Abstract
Expansion-collapse characteristics of interstratified chlorite-montmorillonite were compared with those of montmorillonite and vermiculite. The expansible component of interstratified chlorite-montmorillonite is neither entirely montmorillonitic nor entirely vermiculitic. It shows resistance both to expansion on glycerol solvation after Mg-saturation and to collapse on K-saturation. A model is proposed to explain these experimental results.
