Abstract: This paper for the first time advances the concept of tectonophysicochemistry. It is concerned with the study of the physical and chemical changes occurring under the action of tectonic forces on crustal materials and is a way to study the intimately associated genetic mechanisms of rock deformation and facies changes through gaining a knowledge of the difference in physicochemieal conditions produced by the tectonics, particularly of the influence and control of the chemical reactions and chemical processes due to the difference in partial hydrostatic pressure produced by t e tectonics. It deals with the study of the basic geological theory that explains the physico-chemlcal conditions linking the branch of geoscience about the textures and structures of crustal materials with the branch of geoseience about the composition of crustal materials, It is of practical value in concrete mineral prospecting.
