Abstract: The purpose of this study is to enhance the knowledge of the distribution and acquire information on research and exploration of ore resources in the hinterland of the corridor.Preliminary study shows that China-Mongolia-Russia Economic Corridor can be divided into four metallogenic zones:Sino-Korea metallogenic zone, Ural-Mongolian metallogenic zone, Siberian metallogenic zone and European metallogenic zone.Among them, the Sino-Korean and Ural-Mongolian metallogenic belts are characterized by wide distribution of large-scale Cu-Au, Ag, Pb-Zn and Sn-polymetallic deposits, the European metallogenic zone is characterized by enrichment of Ni-Cu, Fe, Au and Pb-Zn deposits, and the Siberian metallogenic sections are characterized by wide distribution of the Ni-Cu-PGE, Nb-polymetalland diamond deposits.A study of ore-forming pedigree shows that the different tectonic units in this region mainly underwent six stages of crust evolution from the Archaean to the Cenozoic, corresponding to six periods of ore deposits:the TIF-type Fe-deposits formed in Precambrian, the porphyry Cu-Au and magmatic Vi-bearing titanomagnetite deposits formed in Caledonian, the hydrothermal vein-type Au deposits related to the intrusions, Sn-polymetal mineralization, Au, Ag-Pb-Zn, Sn-W and other polymetallic deposits formed in Yanshannian period and some hydrothermal deposits formed in Cenozoic.Main ore species in eastern and central part of the corridor are Cu, Mo, Au, Ag, Pb, Zn and diamond.The main types of deposits are porphyry, hydrothermal vein, LS epithermal, alluvial, and marine volcanic rock types, and main ore species in the western part of the corridor are Fe-Cu, Ni-Cu, Pb-Zn, with the main deposits being of IOCG, porphyry and hydrothermal vein types.
