The determination of the type of stacking in mixed-layer clay minerals

Abstract

X-ray scattering distribution from monodimensionally disordered structures as a function of degree of randomness has been investigated in connection with practical application to the study of two- component interstratified clay minerals, by means of the interference function formula recently developed by G. Allegra. The positions in reciprocal space of the maxima of functions calculated for several statistical configurations and for pairs of spacings occurring in mica-montmorillonite type interstratified minerals, are tabulated. A direct application of these data to the interpretation of some classical and original diffraction patterns is also given
