    4. (Crystallog.) A compound crystal composed of two or more
    crystals, or parts of crystals, in reversed position with

    Note: The relative position of the parts of a twin may be
    explained by supposing one part to be revolved 180[deg]
    about a certain axis (called the twinning axis), this
    axis being normal to a plane (called the twinning
    plane) which is usually one of the fundamental planes
    of the crystal. This revolution brings the two parts
    into parallel position, or vice versa. A contact twin
    is one in which the parts are united by a plane
    surface, called the composition face, which is usually
    the same as the twinning plane. A penetration twin is
    one in which the parts interpenetrate each other, often

    form, cruciform, geniculated, etc.
