(a) Whole-rock powder XRD patterns for the dioctahedral samples studied. Plg denotes plagiclase, I illite, Qz quartz and Sm smectite. The dashed lines, from left to right, indicate the 001, 020, 131 and 060 smectite reflections, respectively. (b) XRD patterns of the oriented aggregates of the dioctahedral samples. Red denotes air-dried oriented aggregate, blue denotes ethylene glycol-solvated oriented aggregate and green denotes heated (823 K) oriented aggregate. |
