TEM image and various magnification of newly formed 2M illite. a TEM image of illite with 2 and 1 nm stacking sequence. The 2M polytype is confirmed by the selected area diffraction pattern. b Layer termination of a illite crystal. The step of two layers are shown by the arrows. The stacking sequence is 1 nm. c HRTEM image of the illite stacking sequence. The 2 nm periodicity is related to the 2M polytype
