摘要
A new selected area electron diffraction (SAED) pattern was found from Fe-illite. The lattice of the ED pattern can be described as a compound tessellation of {3,6}[79{3,6}], which is based on a large coincidence-site lattice (CSL) with oriented crystal associations rotated by a non-crystallographic angle 26°. This phenomenon corresponds to the plesiotwinning of Fe-illite and has been never reported in the nature so far.
