By the use of a model with two kinds of stacking faults it is possible to explain quantitatively X‐ray powder diffraction patterns of disordered kaolinites. The first kind of defect consists of random translations which limit coherent scattering regions in all hk directions except h = k = 0. The second kind consists of shifts between layers of ± n b /3 ( n integer) which limit coherent scattering only in hk directions with k ≠ 3 n . The comparison of calculated patterns with experimental (02,11) and (20,13) bands gives the proportions of different kinds of layer displacements in two disordered kaolinites.
