俯冲和岩浆过程中的地球深部碳循环

地球表层短周期的地表碳循环影响全球气候变化和地球宜居环境,而地球上90%以上的碳存在于地球内部,地球内部长周期的深部碳循环对地表碳循环产生重要影响。介绍了汇聚板块边界、离散板块边界、板块内部和新型海山等不同构造背景深部碳循环的研究现状,并阐述将来需要深入研究的科学问题,包括俯冲带脱碳机制及其效率、碳在地幔中的存在形式等。

Deep carbon cycle and livable earth during subduction and magmatic processes

The short-term surface carbon cycle on the Earth's surface affects global climate change and the Earth's livable environment. More than 90% of the carbon content is stored in the deep Earth. The long-term deep carbon cycle in the Earth's interior has an important impact on the surface carbon cycle. Studying the deep carbon cycle has an important indicator significance for the surface carbon cycle. The carbon cycle is one of the most cutting-edge issues in the interdisciplinary field of geoscience. This paper presented a brief overview of deep carbon cycle in different tectonic backgrounds, such as convergent plate boundary, discrete plate boundary, intraplate environment and new type seamount, and expounds the scientific problems that need to be studied in depth in the future, which may cause the peer to pay more attention to the relevant research of deep carbon cycle, such as decarbonization mechanism and efficiency of subduction zone, and the existing form of carbon in mantle, et al.
