An idea of crystal moduli (CM) as minimum aggregates for constructing of complex crystal lattices is introduced. CM arrangement in crystals is described by means of packing groups Ĝ. Twin structure constructions are demonstrated on the base of CM conception for LiNbO 3 , ZnS and KTiOPO 4 crystals. There are next advantages of CM conception: a) Physically not verified versions of twinning appearing in other theories (Klassen‐Nekludova; Blistanov et al. 1975, 1976a) are automatically excluded; b) CM method allows to describe crystal twinning when transition strata between twin blocks appear. The connection between CM conception and crystal growth mechanism is discussed.
