9.9: TLQS twinning
TLQS (Twin Lattice Quasi-Symmetry) twinning is a term employed to indicate twinning where the twin lattice is close to a higher holohedry . The degree of quasi-symmetry is commonly measure by the twin obliquity , which depends on the perpendicularity of lattice row / lattice plane [ uvw ] / ( hkl ) defining the cell of the twin lattice .
