Аннотация: The genetic diversity of the structure and mineral composition of the ores of the Gorevskoe Pb–Zn deposit and the main signs of synchronous ore deposition from near-bottom ore-bearing solutions associated with sedimentation processes in a sedimentary basin were established. The structural and textural features and mineral associatiПоказать полностьюons of ores accompanying different metamorphic and postore processes are discussed. The succession of hydrothermal synsedimentation origin of the Gorevskoe Pb–Zn deposit during the direct deposition from near-bottom ore-bearing solutions is considered in more detail. It is suggested that two types of ores, varying in material composition, textural–structural features, morphology, and location reflect the ore-facies zoning of the unified ore-hydrothermal system. The banded Pb–Zn ores belong to the distal parts of the system; brecciated, mainly Pb, ores—to the proximal ones. The important role of the postore processes of regional and dynamothermal metamorphism in the transformation and redistribution of primary sedimentary ores was revealed. This research is based on the detailed study of textural–structural features of ores in polished and ground samples. The modern research methods were applied to examine microtextural and mineral features and composition of ore and nonmetallic minerals. In general, the ores of the Gorevskoe deposit demonstrate the structural and textural features of synsedimentary deposition, synchronous with the formation of host carbonaceous–micaceous–siliceous–carbonate rocks, preserving the main structural features at both the macro and micro levels. The results obtained are compared and analyzed with other polymetallic deposits of Russia and other regions worldwide.
