  • 4. (Crystallog.) A compound crystal composed of two or more crystals, or parts of crystals, in reversed position with reference to each other. [1913 Webster]
  • 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 very irregularly. Twins are also called, according to form, cruciform, geniculated, etc. [1913 Webster]
