= Overlap of lattices =

By effect of a ''[[twinning operation]]'', both the direct and reciprocal lattice of the individuals forming a twin are overlapped. Overlapping (restoration) of nodes belonging to different individuals can be: (i) exact and total ([[twinning by merohedry]]); (ii) exact but partial (i.e. only a fraction of the nodes of an individual lattice is restored; [[twinning by reticular merohedry]]); (iii) total but approximate ([[twinning by pseudomerohedry]]), approximate and partial ([[twinning by reticular pseudomerohedry]]).
[[Twin lattice]], [[twin index]] and [[twin obliquity]] are entries related to the overlap of lattices.
