En opposition avec les magmatistes, une fraction importante des spécialistes a adhéré à la théorie d'une formation du granite par diffusion de substances chimiques dans le milieu solide (ou pour mieux dire : milieu cristallisé). Le milieu se serait trouvé «granitisé» par métasomatose sans passer par un état liquide. C'est la théorie «transformiste» ou «métasomatiste». 2, record 1, French, - transformisme

basic front : In granitization, an advancing zone enriched in calcium, magnesium, and iron, that is said to represent those elements in the rock being granitized that are in excess of those required to form granite.

In favour of the immobility of inclusions, one can recall the classic observations of the alignments of inclusions prolonging in the granite certain layers of the surrounding rock. Such alignments may coincide with differentiation bands in the granite of a hybrid facies, which mark the place of particular layers within the framework of the granite mass, layers which can be continuously followed throughout it. As H. H. Read(1953) says :"phantom stratigraphies within the interior of granite masses are the only proof of a granitization in place". 1, record 10, English, - phantom%20stratigraphy

Van Bemmelen [attributed] the cause of tectonic deformations to a geochemical evolution connected with the diffusion of ions and atoms and expressed by the granitization of originally basic rocks, which would result in a strong diminution of their density. Isostatic readjustment would then be accompanied by important uplifts(...), following which gliding tectonics would take place, involving great masses and even affecting the crystalline crust. Beginning with more or less vertical uplifts, isostatic readjustment would explain the somewhat tangential tectonic structures that are to be observed on the surface. 2, record 11, English, - Van%20Bemmelen%27s%20hypothesis

Le réajustement isostatique entraînerait alors des soulèvements importants (...) à partir desquels jouerait une tectonique d'écoulement par très grandes masses, affectant même l'écorce cristalline; elle expliquerait, à partir de soulèvements essentiellement verticaux, les accidents tectoniques plus ou moins tangentiels que l'on observe en surface. 2, record 11, French, - hypoth%C3%A8se%20de%20Van%20Bemmelen
