| 摘 要： | 锌同位素体系是海洋地球化学研究的新示踪剂，应用于示踪海水中锌元素的来源及其运移过程.海洋沉积物作为锌元素重要的"源"与/或"汇"，其锌同位素组成的研究有助于理解海洋锌元素的地球化学循环.海洋沉积物记录了海水组成的信息，可以反演古海水锌同位素组成的变化，前提是理解沉积物与海水之间的分馏.对海水及海洋不同储库锌同位素研究进行系统总结，包括河流输入、热液体系、不同类型海洋沉积物(如富碳酸盐的沉积物、陆源硅酸盐碎屑、硅质沉积物、铁锰结核、贫氧-缺氧沉积物)的锌同位素组成，阐述了海洋沉积物锌同位素组成变化在古气候、古环境重建以及古海洋学等领域的应用以及重要性.

| Abstract: | Zinc isotope represents new tracers of oceanography, which is used to trace the source and migration of zinc in seawater. As important sources and/or sinks of zinc, the study of zinc isotopic composition of marine sediments is of great significance to our understanding of geochemical cycling of zinc. In addition, marine sediments record the composition of seawater, and the study of zinc isotope fractionation between marine sediments and seawater is a prerequisite for tracing zinc isotopic composition of ancient seawater. In this paper, researches on zinc isotopes of seawater and reservoirs in the ocean are systematically summarized, including zinc isotope study of riverine inputs, hydrothermal systems and different types of marine sediments (carbonate-rich sediments, terrigenous silicate fragments, siliceous sediments, ferromanganese nodules and suboxic/anoxic sediments), to explain the applications and importance of zinc isotope variations of marine sediments in paleoclimate, paleoenvironment and paleoceanography. |
