The subduction system of the plate can be regarded as a factory . The subduction recycling studies emphasis on the behavior, paths, and quantitative analysis of all types of components in the subduction material. Sediment subduction and subduction erosion result in the return of continental crust material to the mantle.According to the initial estimate, the rate of continental crust returned to the mantle is approximately equal to that of continental growth result from magmatic activity. The net growth rate of continent may be close to zero in the most recent geological time . Geochemistry characters of oceanic-island basalt suggest that the slab which descend into the mantle may be mixed with the source area of plume . Subduction recycling process has a major effect on the dynamics and evolution of the crust and mantle.
