In the Early Mesozoic period intercontinental movements of the Junggar and Tuva-Mongolian lithosphere terranes were accompanied by the deformation of the Paleozoic tectonic substrate and by the formation of a new tectonic system of Inner Asia, the Altai collision belt. The qualitative change of the initial structure covered more than 30% ~35% of the region. and the zonal distribution of these new formations determined the belt configuration and inner peculiarities. Residual mosaic-block terranes of the Paleozoic substrate and specific collision systems are distinguished and described in this paper. The main elements of these structures are crumple zones (collision sutures). Analysis of the rock massif regional dynamometamorphism and the spatial distribution of stress-formations in Altai is the principal peculiarity of the method for recognizing the Early Mesozoic collision system. Tectonites of destruction zones (D-tectonites ) . cataclastic flow (C-tectonites ) and plastic flow (P-tectonites) are the members of these formations. Each kind of tectonites is specific for conditions of the initial substrate transformation during the collision and has its own indicator peculiarities. Isotopic dating of stress-formations in Altai gives 260~230 Ma.
