| Abstract: | The metallogenic efficiency of the marginal sea lithosphere of Northeastern Asia is associated mainly with the ore formation
variety of the remaining cratons and microcratons that defined the structural peculiarity of the region; these are setoffs
of the Precambrian basement, brachyform, anticline highs, and genesis of rifts within TMA periods. These formations allowed
us to explain the reasons for the unique metal-bearing feature of the marginal sea lithosphere of the Pacific Ocean ore belt
in addition to phenomena of an inherited nature of mineralization and conditions of formation of polychronous ore deposits. |
