Polymetallic deposits of lead and zinc are of great importance in the economy of the developed countries of the world. Kazakhstan is among the world leading countries in terms of reserves and production of lead and zinc. There are large ore regions with polymetallic mineralization; these are the deposits of the Atasu and Uspensky ore regions in Central Kazakhstan. The former are genetically related to the final (taphrogenic) phase of the development of the large orogenic structure in the Central Kazakhstan (the Devonian volcano-plutonic belt), with the period of Late Frasnian-Famenian-Early Carboniferous formations of thick carbonate and carbonate-terrigenous sediments, including significant reserves of stratiform lead-zinc ores. Polymetallic mineralization of the Uspensky zone is singled out as an independent genetic Alaygyr type, and the tectonic nature of the ore-bearing Uspensky zone, as well as mineralization of this type, is still the subject of constant discussions. In this regard, the comparative characteristics of the Dalnegorsky and Uspensky ore regions, which have certain similarities in geodynamics, magmatism and metallogeny, are of great importance not only for solving the issues of the general patterns of formation, factors and criteria for controlling lead-zinc mineralization but also for an objective assessment of the ore potential of these and similar areas with polymetallic mineralization. Research methods: comparative analysis of the results of petrographic, chemical and mineralogical studies of ores enclosing near-ore metasomatically altered rocks and intrusions of different age and composition.
