Part of the book: New Frontiers in Tectonic Research
General regularities in the formation of tectonic and metallogenic structures are considered as a scientific basis for forecasting new deposits of nonferrous, precious and rare metals in the territory of East Kazakhstan and are considered on the basis of modern geotectonic concepts of the Earth self-development. Regular connections between the main ore-bearing structures and the leading geological-industrial types of deposits are determined with features of the deep crustal structure and certain geodynamic settings of various geotectonic cycles and eras (from the Precambrian to the Quaternary). The belt placement of ore deposits is emphasized with the identification of four ore belts: Rudny Altai (Cu, Pb, Zn, Au), West Kalba (Au, Ag), Kalba-Narym (Ta, Nb, Be, Li, Sn, W) and Zharma-Saurs (Cr, Ni, Co, Au, TR). In the location of gold ore deposits, the Zaisan suture zone, formed in the collision zone of the Kazakhstan and Siberian lithospheric plates, is the ore-controlling value. Spatial-genetic connections of rare metal and rare-earth deposits with granitoid belts formed in post-collision (orogenic) geodynamic conditions of Permian time are determined. The research is aimed at strengthening the mineral and raw material base for the operating enterprises of the East Kazakhstan region.
