Twin lattice
A twin operation overlaps both the direct and reciprocal lattices of the individuals that form a twin; consequently, the nodes of the individual lattices are overlapped (restored) to some extent (twinning (effects of). The lattice that is formed by the (quasi)restored nodes is the twin lattice. It corresponds to the crystal lattice in twinning by merohedry and to a sublattice of the crystal (individual) in twinning by reticular merohedry.
