Mirolyubovsky latitudinal long-term activation fault had a decisive role in distribution of tungsten-greisens and hydrothermalites of the same granite massif, in which the main ore bodies were localized in meridional discontinuities that cut across Kalbin granites and leucogranites of the monastirskiy complex. At the final stage of the Hercynian tectonic magmatic cycle, the Mirolyubovsky fault was transformed into a fault-shift with displacement of all

Favorable factors of ore formation include the multistage structure of the Kalba-Narym pluton in the form of alternating cross sections of granite plates and enclosing sedimentary rocks, which caused formation of structural traps and screens for pegmatite fields. Apical parts and above intrusive zones of granite massifs, their apophyses, hidden domes and tectonically weakened zones saturated with vein formations are the most promising for the concentration of rare metal mineralization. According to geological and geophysical data, the main ore sites and ore fields are spatially located in a thickened part of granite massifs, above the magmatic-

**The Zharma-Saursky belt** was formed on the northeastern outskirts of the Kazakhstani massif, and it is characterized by complex geodynamic development and polycyclic metallogeny. It unites three metallogenic zones: Charskaya, Zharma-Saurskaya and Sariktas-Sarsazanskaya. Charskaya zone is a structure of regional or planetary rank, and it has a long and complex history of development. Within its limits, the Charsko-Gornostaevsky ophiolite belt is distinguished which is fixed by separate fragmentary outcrops of Precambrian metamorphic rocks, protrusions of hyperbasites, thrust zones and serpentinite melange [2, 18, 21]. In the Precambrian cycle, the primary ores (Cr, Ni, Co, Cu) formed in the oceanic geodynamic environment are associated with the hyperbasite formation (Charsky complex, PR?). The ores belong to the hysteromagmatic chromium, magmatically liquation and hydrothermal copper-

Zharma-Saurskaya zone, located in the central part of the ore belt, developed under the influence of a deep mobile zone (DMZ), was characterized by an elevation of the upper mantle and a high-power metabasalt layer (24 km). The focal part of the DMZ was characterized by high magmatic saturation with a strong development of syncollision intrusions of gabbro-diorite-

Cardinal changes in views on the Earth development and world geological science have occurred in recent years on the basis of provisions of modern geotectonic hypotheses (new global tectonics, tectonics of lithospheric plates, terranean tectonics, plumectonics, and so on). Identification of regular relationships between cyclically directed self-development of geological structures and ore formation processes in certain geotectonic cycles and epochs is of fundamental importance [11]. Mineral and raw materials sector continues to be the basis of economies in many countries, but experts point to the depletion of the world's mineral resources. The most important task is to open new mineral deposits taking into account current trends in world geological science. This is of particular importance for East Kazakhstan region territory—a unique geological test site, where there is an urgent need to replenish ore reserves of deposits exploited by mining and metallurgical enterprises.

The considered territory of East Kazakhstan, located in the Central Asian mobile belt, is a unique geological providing ground that unites many deposits of ferrous, nonferrous, precious, rare metals and other minerals. For decades, accumulated large factual material on geology, tectonics and metallogeny has been traditionally tied up from the positions of classical geosynclinal hypothesis [22]. The Irtysh-Zaisan and Chingiz-Tarbagatai fold systems were distinguished here, including structural-formational zones, ore-bearing structures with their own set of geological and ore formations. In recent years, from the new theoretical positions, the main problematic issues of geodynamic and metallogenic development of geological structures have been considered in a trilogy "Big Altai" (BA) and a number of other publications [2, 3, 6, 20, 21, 23, 24]. Based on these studies results, the emergence and formation of large geological structures in Kazakhstan, Siberia, the Urals and other regions are associated with Eurasian continent disruption into individual slabs, geoblocks, massifs and detachments in the late Proterozoic that migrated and experienced complex development in the evolution of the Paleo-Asian ocean (Buslov, 2011; Geodynamics, 2007). According to paleomagnetic and geodynamic reconstructions, it is assumed that modern geological structures (the Rudnyi Altai, Kalba-Narymskaya, West-Kalbinsky Zones and others) are erratic masses of paleocontinents (Eastern Gondwana, etc.), possibly terranes, that drifted in the Paleo-Asiatic ocean and interlocked in the collision stage (C<sup>1</sup> -C<sup>3</sup> ) when Kazakhstan and Siberian lithospheric plates collided. Paleogeodynamic analysis of the BA structure formation was carried out from the Precambrian to the Cimmerian and Alpine cycles inclusive. As a result of a complex polycyclic development of tectonic magmatic processes and metallogeny in the region, a system of ore belts and metallogenic zones that unite many types of mineral deposits was formed.
