Geological structure and ore-­bearing Oldongsinskaya and Uguyskaya graben-­synclines

The discovery of new types of ore deposits of gold, silver, platinum, nickel and other metals, which are localized in sedimentary basins in the 90s. The results of more intensive studies of sedimentary basins have become an extensive data, that is critical for developing of understanding of their metallogenic potential, as well as the geodynamic conditions and environments of formation of sedimentary rocks.
