Dear clay experts,

I am looking for some methods to quantify clay particle (e.g., smectite and illite) orientation through X-ray powder diffraction patterns (or other better analytical or imaging techniques). Could you direct me to some references?

For example, kaolinite orientation index, an old technique is to use the ratio of intensity of a basal reflection to that of a prism reflection (060): I(001)/I(060).

Please reply to my email: zhangg at umass.edu.
