The orientation and problems of contemporary intra-continental physics and dynamics

Abstract：The structure of the crust and the mantle and the dynamic mechanics of intra-continent are more complicated than those of the 'rigid' oceanic plate, and hence the plate tectonics of the continent should be redefined i.e., it is necessary to recognize the differentiation, modulation and motion of the material inside the continent under the force system and reestablish the deep process and mechanism of continental formation. This paper presents ten basic problems of the geodynamics based on the structure of the crust and the mantle. The key subjects of these problems include the exchange of deep process and material, the movement and behavior and the dynamic response.
