In our time, the manifestation of significant interest in natural mineral individuals of nanometric dimensions has become natural and necessary. A new branch of geological science, nanomineralogy, has also been developed. An analysis of the data accumulated on this problem made it possible to speak of two ways for the formation of natural nanosized crystals: a) crystallization and b) deformation. The first of them, crystallization, is the natural origin of the crystallization of any mineral individual in its characteristic initial period. Convictions are expressed that all crystalline particles — germs — have nanosizes, and all minerals began their development from nanocrystals. The appearance of individuals of this size is also characteristic of the initial stages of recrystallization of volcanic glasses. Nanoscale values are characteristic, for example, of opals. The second way is deformational, when the development of geological matter is determined by the peculiarities of tectonic evolution, its geodynamics.
