Seismic tomography reveals important evidences of subduction slab within the mantle, which involves a variety of geometries and modes of motion. The mantle transition zone is an important barrier to subsidence, where subduction slabs stagnate, deform and lithosphere material accumulation. Plate in some areas can be subducted to the core - mantle boundary, the accumulation of the formation of plate cemetery, resulting in D’’ layer material composition and thermal heterogeneity. High- temperature and high- pressure experiments and rheological calculation simulation provide new constraints on the composition and physical properties of the mantle. During the subduction of the mantle, plate mineralization involves the constraints of mineral phase transitions, viscosity, density, and mechanical strength of the carbendazim, Mantle transition zone is an important interface of phase change. Based on the study of plate subduction, a new mode of global convection of the mantle is proposed. The plate grave has a causal relationship with the super mantle plume and has become an important link in global mantle convection and needs further study. Plate subduction is the connection between the superficial plate tectonics and deep super mantle plumes and an important driving force.
