BASIC IDEAS OF THE MULTISPHERE TECTONICS OF EARTH SYSTEM

The basic concepts of the multisphere tectonic view of the Earth system are to place the Earth as a living celestial body in the cosmic system,considering more about the interaction among the deep crust,mantle and core of the earth and the effect of the extraterrestrial celestial body on the Earth movement. This tectonic view holds that tectonic movement is not only the interaction between the lithospheric plates,but also the global dynamic process of the Earth system. The continent and the ocean are the unity of opposites and can be transformed into each other,and the conception of simple continental accretion should be regarded as invalid. The mantle convection hypothesis has not been confirmed so far,and the continental blocks are active,but they can't largely drift at random. The continental crust growth should not be thought to be achieved by simply lateral or vertical accretion,but the product of the multicyclic tectono-magmatism superposition. The tectonics of the Earth has not been developed by uniform changes,but by nonuniformitarian and nonlinear cyclic evolution. The Earth's surface layer has different tectonic patterns controlled by the corresponding deep fault systems in different geological stages,and the Atlantic-Indian-Pacific oceanic basin systems only emerged since the late Mesozoic.
