The Middle and Lower Reaches of the Yangtze River transitional tectonic node has classical geological phenomena, complex structures and clear tectonic process, which is a concentrated display of various structures of time-space connection since the Mesozoic in eastern China. The main contents of this transitional tectonic node include: 1） three tectonic types: continental orogenic belt （the Dabie orogenic belt）, continental margin shear zone （the Tanlu fault belt） and intracontinental hotspot （the Lower Yangtze hotspot）, 2） three stress modes: the compressional stress of SN trending between the South China and North China plates, the east Asian continental margin shear under the subdution of the Pacific Plate and the Lower Yangtze hotspot under the extensional background of eastern China, 3） three major transformation mechanisms: tectonic regime transformation from the Tethys to the Pacific tectonic domain, the compression direction shift from SW-SE to near S-N to SE-NW trending in the Mesozoic, and stress mode transformation from regional compression to extension. Obviously, the structures, properties and process of the transitional tectonic node of the Middle and Lower Reaches of the Yangtze River full records the sequential changes in tectonic evolution and the variety of structural properties, shows the deep process and shallow response under complicated dynamic background, and reveals the special global lithospheric dynamics process.
