Plate tectonics is a complex dynamic system and subduction is one of the most important features, which, however, has not been completely understood. In the last decade, based on the obtained evidence in geophysics, tectonics, petrology and geochemistry, numerical simulation applied in subduction zone research have achieved many breakthrough contributions. The plume upwelling switched subduction can happened at the juvenile stage of the planet evolution. The weak shear zone that formed by the dehydration of the subduction slab is the dominant impact factor for the one-sided asymmetric subduction pattern. The chemical composition of the subduction magma mainly depends on the subduction evolution processes. Both intensity of the melt extraction and the age of the subdcution slab have influence on the volume of the accreted crust.
