Figure 6

Degree of crystallinity of smectitic and interstratified components of the paleosol samples and the parent material. (a) Examples of profile fitting analysis obtained for clay samples of selected horizons; (b) Full width at half maximum (FWHM) of paleosols and rock samples. The lower the FWHM, the better the crystallinity and vice-versa. Smectitic component of P1 and P2 in red and blue, respectively. Interstratified component of P1 and P2 in green and orange, respectively. Smectite of rocks samples in pink. Each symbol represents one horizon. Note the smectitic component is more crystalline than the I/S component. Smectite from the rocks has a higher crystallinity with lower FWHM values.
