Abstract
As a result of long-term geological and sedimentological investigation of the Gyumushlug stratiform lead and zinc deposit in the carbonate strata of the Middle Devonian and study of the geological structure of the Sharur massive of the territory and adjacent areas, it became possible to develop its sedimentary ore genesis. The source of metals for the formation of the deposit was not hypothetical hydrothermal solutions, as was confirmed by previous researchers, but polymetallic deposits and manifestations developed on the Baikal basement of the Zangezur microcontinent. The formation of ore deposits of the Gyumushlug tested a difficult and long path, amounting to several hundred million years. Three stages of ore formation were established: sedimento-logical-diagenetic; catagenetic with the participation of hot highly mineralized chloride-sulfate-calcium-magnesium groundwater; tectonic, which manifestate on the border of the Late Triassic and Early Jurassic as a result of the activation of the Early Alpine phase of tec-togenesis...
