4. (Crystallog.) A compound crystal composed of two or more

reference to each other.

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.
