The direct lattice element about which a twin operation is performed. Twins are classified accordingly in:


  • reflection twins, if the twin element is a lattice plane (the twin plane)
  • rotation twins, if the twin element is a lattice direction (the twin axis);
  • inversion twins, if the twin element is an inversion centre (the twin centre).
