板块的俯冲系统可以比拟为一个工厂。再循环研究强调对俯冲物质各种组分的行为、去向的追踪和定量分析。沉积物俯冲和俯冲侵蚀作用导致陆壳物质返回地幔,初步估算表明,大陆物质返回地幔的速率与岩浆活动导致陆壳生长的速率在数量上大体相当,晚近时期陆壳的净增长速率可能近于零。大洋岛玄武岩地化特征上的多样性提示,沉入下地幔的板片可能从深部卷入地幔柱的源区。俯冲再循环过程对地壳、地幔的动力学和演化产生深刻影响。

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.
