From China to Russia,Tan-Lu fault system stretches for thousands of kilometers,towards NE 30°.The authors have collected more than ten magnetotelluric profile that China and Russia have carried out,in the studied area of the Tan-Lu fault’s northern section,and have analyzed electrical characteristics of the relevant profiles.Deriving the following conclusions:(1)Jiamusi-Bureya plots,etc.,demonstrate the high resistance of Kernel;(2)Fold belt attributed to the land showed high and low resistance stitching,associated with not only terrane accretion,but also upper mantle upwelling;below the sedimentary basin,the resistivity of the upper mantle is lower and closer to the surface comparing with the adjacent area(100-150);(3)In the system of Tan-Lu fracture,Yishu and Dunmi fracture,etc.are expressed as vertical low-resistivity zone;(4)There may exist subducted old-fashioned piece under Jiamusi and Bureya plots. From China to Russia, Tan-Lu fault system stretches for thousands of kilometers, toward NE 30 °. The authors have collected more than ten magnetotelluric profiles that China and Russia have carried out, in the studied area of ​​the Tan-Lu fault’s northern section , and have established electrical characteristics of the relevant profiles. (1) Jiamusi-Bureya plots, etc., demonstrate the high resistance of Kernel; (2) Fold belt attributed to the land showed high and low resistance stitching, associated with not only terrane accretion, but also upper mantle upwelling; below the sedimentary basin, the resistivity of the upper mantle is lower and closer to the surface comparing with the adjacent area (100-150); (3) In the system of Tan -Lu fracture, Yishu and Dunmi fracture, etc.are expressed as vertical low-resistivity zone; (4) There may exist subducted old-fashioned piece under Jiamusi and Bureya plots.
