 Based on the theory of continental tectonics and dynamics, the authors provide a comprehensive overview of recent research results with a particular attention to four important scientific problems on the Chinese (East Asian) continent: 1) tectonics of the mantle beneath the Chinese continental lithospheric plate. Seismic tomographic profiling reveals that the western Pacific slab is subducted westward to depths of 400~600 km beneath the East Asian continent, and the subducted slab becomes subhorizontal and listric-shaped in the mantle transitional zone; 2) reactivation of the Chinese continent’s metamorphic basements; 3) the tectonic backgrounds and processes for the formation and exhumation of HP-UHP metamorphic belts in China; and 4) three categories of mechanisms for the extrusion of deep materials within the Chinese continental orogenic belts: constrictional extrusion; lateral extrusion; and transcompressional extrusion.
