Abstract
Stacking faults in lizardites 1T (polytype group A) have been studied by analyzing the oblique-texture electron diffraction patterns in combination with a numerical simulation of diffraction patterns. The simulation of diffraction profiles was performed for finite (10-layer) sequences using the statistical Markov model in the quasi-homogeneous approximation. Diffraction criteria are revealed, which indicate the presence of defects in lizardite 1T; these defects are related to the change in the layer orientation by 180° and displacements of adjacent layers by a/3. It is shown that in the case of the statistical distribution of defects, along with pairs of adjacent layers with layer packing features typical of polytype groups D and B, there are also sequences of layers 1T(A), correspondingly rotated by 180° or displaced by a/3 and 2a/3 with respect to the layers in the 1T matrix. The data obtained give deeper insight into the variations in layer packing in lizardites 1T.
