英文摘要	In order to understand the deep structure of lithosphere more comprehensively and objectively in Nanjing (Ning)-Wuhu (Wu) and explore lithospheric thermal structure and crust, mantle status and other important scientific issues, and provide the basis for ore district mineralization and metallogenic regularity, we finish 6 MT profiles and discuss the "apparent three-dimensional" conductivity structure of crust-upper mantle through imaging studies. Find that a big low-resistivity layer exists in crust-upper mantle, and the layer is substantially continuous, but disconnects in Chaohu fold belt region. Combined with regional heat flow results, we believe that the lower crust-upper mantle is conductive, and "melt" or "aqueous shear fracture" may be existed, and the state of matter is likely to be hot and weak. In addition, we infer the location of upper mantle uplift and distribution range of the Yangtze River deep fault through the material and electrical properties, and we consider that the Yangtze River fault is not only exist, but also composes by a number of faults, and the faults is more complex and deep in the north.
