| 摘要: |
| 同位素已成为俯冲带岩浆作用研究中灵敏的地球化学示踪剂, 是约束岩浆运移过程和时间尺度的有力工具。综述了近几十年来利用Sr-Nd-Pb-Hf 同位素、Li 和 B 同位素以及Be 和短周期铀系同位素等方法, 在俯冲带岩浆作用过程、时间尺度、岩浆源区物质特征、岩浆形成演化及控制机制等方面取得的进展和成果。最后指出将不同同位素研究应用于弧后盆地岩浆作用的研究中, 必将为全球俯冲带岩浆作用研究带来突破性的进展和成果。 |

| Abstract: |
| Isotopes are sensitive geochemical tracers for use in the study of magmatism in subduction zones and are useful for constraining magma migration processes and time scales. This study summarizes a number of advances and achievements in the study of magmatic processes, including time scale, magma source characteristic, magma evolution, and control mechanisms in subduction zones using Sr–Nd–Pb–Hf isotopes, Li and B isotopes, and Be and uranium series isotopes methods. We concluded that the use of these isotopes in back-arc basin magmatism research will enable breakthroughsin global subduction zone magmatism research. |
