Twin"ning, n. (Crystallog.)
Definition: The assemblage of two or more crystals, or parts of crystals, in reversed position with reference to each other in accordance with some definite law; also, rarely, in artificial twinning (accomplished for example by pressure), the process by which this reversal is brought about. Polysynthetic twinning, repeated twinning of crystal lamellæ, as that of the triclinic feldspars.
– Repeated twinning, twinning of more than two crystals, or parts of crystals.
– Twinning axis, Twinning plane. See the Note under Twin, n.

4. (Crystallog.)
Definition: A compound crystal composed of two or more crystals, or parts of crystals, in reversed position with reference to each other.
Note: The relative position of the parts of a twin may be explained by supposing one part to be revolved 180Âş 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 very irregularly. Twins are also called, according to form, cruciform, geniculated, etc.
