1959 Amer. Mineralogist 44 1067 [The geometrical relationship between two crystals] may usually be expressed by any one of several possible twin operations, which (as is well known) are all the symmetry operations that are deficient in the merohedral crystal symmetry but are present in the next-higher merohedry.
1980 Proc. National Acad. Sci. U.S.A. 77 278/2 This behavior suggests that the crystals suffer from twinning by merohedry about the a3 axis.
1998 Amer. Mineralogist 83 631 The crystal showed twinning by merohedry according to m210, which was accounted for in the calculations.
