3
: the assemblage of two or more crystals or parts of crystals such that they form a twin (see twin entry 1 sense 3)
One of them, a spiral defect, typically occurs when atoms crystallize from a high-temperature vapor. In the other defect, known as twinning, atomic lattices that are mirror images of each other join at a common boundary.
R. Cowen
R. CowenThe two-time Nobel laureate Linus Pauling, for example, championed an arrangement of ordinary crystals called twinning. Twinned crystals grow from separate origins and penetrate each other at odd angles, such as 72 degrees. This might produce a diffraction pattern with spurious fivefold symmetry, even though the underlying structure was conventional. Hans C. Von Baeyer
