Комиссия IMA по новым минералам и названиям минералов: нормы и рекомендации по номенклатуре минералов, 1998 Закономерное размещение между слоями

Regular interstratifications of two or more minerals are accepted as separate species if the kinds of layers, their relative proportions, chemical compositions, and regularity of interstratification in three dimensions on a micrometric or nanometric scale have been well documented. Such information can commonly be obtained by transmission electron microscopy (TEM) using lattice-imaging techniques. However, if the evidence for regularity of stratification is based on X-ray diffraction data, then the criteria of Bailey (1981) should be applied.

Example: A regular interstratification of talc and a trioctahedral smectite qualifies as a separate mineral species, aliettite.
