    • n twin A compound crystal one part of which is in a reversed position with reference to the other, as if it had been revolved through 180° about an axis (twinning-axis) perpendicular to a plane which is called the twinning-plane, and is usually a fundamental plane of the given Crystal. Thus if (fig. 1) one half of the octahedron as indicated is revolved through 180° about a vertical axis, the twinned octahedron of fig. 2 results, the twinning-plane being here a face of the octahedron; such twins are common with spinel, and are hence called spinel twins. This is also called a juxtaposition- or contact-tu in, in distinction from a penetration-twin, such as is represented in fig. 3, where each crystal is complete and interpenetrates the other. If the molecular reversal is often repeated in the growth of a crystal, a poly-synthetic twin may result, consisting of successive thin layers or lamellæ of two sets, alternately in reversed position to each other. This is common among the plagioclase feldspars, and is the cause of the fine striatiou often observed on a cleavage-surface. (See albite twin and pericline twin, below.) When the angle between the axes of the two parts of the twin crystal is an aliquot part of 360°, repeated twinning may occur (thus, 3 × 120°, 4 × 90°, 5 × 72°, etc., complete the form); the resulting compound crystal may then imitate (mimetic form) a form of higher symmetry than belongs to the sin*gle crystal, and hence be a case of pseudosymmetry: for example, the twins of aragonite (which has a prismatic angle not far from 120°) have often the form of a pseudo-hexagonal crystal; the six-rayed stellate twins of cerusite give another common example of a repeated twin. In some cases the imitation is so perfect that the true nature of the form can he determined only by an investigation in polarized light.
    • twin To couple; pair; mate; join intimately or link together; said of two united or of one joined to another.
    • twin Specifically, in mineralogy, to form or unite into a compound or twin crystal by a reversal of the molecular structure according to some definite law.
