Figure 5. Multiple XRD patterns of trioctahedral smectite showing the d001 and d060 reflections. The d001 reflection shift from 13.7 to 17.1 Å after glycolation. The peaks at 9.34 Å and 7.05 Å, not expanding after glycolation, suggest the presence of talc and chlorite respectively. GLY = XRD pattern after glycolation.
