Stacking Fault Simulations – II · Exercise files are found here Introduction: In this exercise and the next you will simulate some diffraction patterns from kaolinite clays. Kaolinite, Al 2 Si 2 O 5 (OH) 4, is a 1: 1 layer silicate with a single unique sheet with AlO 6 octahedra on one side and SiO 4 tetrahedra on the other. The layers stack with an offset to ideally form a triclinic C1
