Аннотация: The article discusses the fundamental issues of Geology and metallogeny of Tuva and adjacent territories of Central Asia. The Tuva-Mongolian segment is one of the largest stable geological blocks of the Central Asian folded belt (TMS TSASP). New information on geochronology and metallogeny of endogenous processes manifested in tsasПоказать полностьюp TMS was obtained. In the late Precambrian - early Paleozoic, they were associated with the specific evolution of the Paleoasian ocean, the nature of the interaction of volcanic island arcs with the oceanic plate and the conditions of the crowding of acretic prisms. In the Vend-Cambrian period, systems of island arcs and inter-arc basins were formed. In the result of shear dislocation and protrusion of ultrabasic rocks, the subsequent formation of the granitoid massifs in collisional stages and manifestations of post-magmatic processes that formed deposits of polymetallic, rare - and noble-metal right ores. The long-term nature of evolution caused the multi-act nature of the accretion belt with the age shift of accretion, collision and post-collision processes, each of which is associated with a certain complex of magmatic and ore formations, which was the main reason for the manifestation of the General lateral metallogenic zonality not only in the selected time intervals, but also with the spatial combination of different age mineralization in the same tectonic zones.
