| 摘 要： | 地幔氧逸度通过改变含碳相的存在形式和迁移方式来影响深部碳循环。本文结合最新的地幔氧逸度实验模拟和岩石学研究成果,探讨了地幔氧逸度时空分布对深部碳循环的影响。文章重点结合地幔减压熔融形成洋壳、新生洋壳蚀变、洋壳俯冲变质、深俯冲洋壳熔融以及俯冲洋壳物质(流体和固体)通过岩浆(岛弧和地幔柱)作用循环出地表等重要地质过程,探讨了伴随洋壳俯冲作用的深部碳循环过程。由于地幔氧逸度的时空变化,俯冲带含碳相表现出不同的存在形式和迁移能力。通过对西南天山俯冲带碳循环的岩石学和实验研究,我们认为应当进一步深入研究俯冲带氧化还原状态及其对俯冲带深部碳循环的影响。

| Abstract: | Oxygen fugacity of Earth's mantle plays a significant role in deep carbon cycle through changing the speciation and migration approaches of carbon-bearing phases in deep Earth. In this study, combining the latest experimental and petrological research achievements on the oxygen fugacity of Earth's mantle, we discussed the effect of distribution and evolution of oxygen fugacity of Earth's mantle in time and space scale on deep carbon cycle. On the basis of the key geological processes of formation of oceanic from the mantle through decompressive melting, alteration of newly formed oceanic crust, metamorphism of subducted oceanic crust, melting of deep subducted oceanic crust, and recycled oceanic crust (solid and fluid) to Earth's surface through magmatism (IAB or OIB), we discussed the deep carbon cycle process along with subduction of oceanic crust. Carbon shows various speciation and migration approaches along deep carbon cycle process due to the influence of the variety of mantle oxygen fugacity. Through the petrological and experimental studies on the deep carbon cycle in the Southwest Tianshan subduction zone, we think further studies on the redox state of subduction zone and its effect on the deep carbon cycle in the subduction zone are needed. |
