摘　　要：作为“金属稳定同位素家族”中的重要成员之一,锌同位素自20世纪就受到了国际地学界的关注。进入21世纪后,随着多接收电感耦合等离子体质谱仪(MC-ICP-MS)测试技术的发展,锌同位素在地球及行星科学中的应用得到了极大拓展。本文比较全面地总结了锌同位素的标准物质和分析测试方法、自然界主要储库的锌同位素组成、锌同位素在不同地质过程中的行为及分馏机理,以及锌同位素在地球科学研究的新进展,包括:(1)示踪再循环沉积碳酸盐和再循环洋壳以及约束玄武岩成分变化机制;(2)示踪成矿物质来源、微生物成矿以及指示矿产勘查;(3)揭示月球的起源与演化过程;(4)指示初级生产力和有机质埋藏变化等生物地球化学过程以及揭示生物灭绝机制。未来,随着锌同位素微区原位分析技术的发展,锌同位素必将在地球科学(尤其是矿床学)和生物医学等领域中得到更加深入与广泛的应用。As one of the most important members of the metal stable isotope family,zinc isotopes have attracted quite a lot of attention by international scientific community since the last century.In the 21st century,with the development of multi-collector inductively coupled plasma-mass spectrometry(MC-ICP-MS),the applications of zinc isotope have been greatly expanded and deepened in the Earth and planetary science.Here we provide a relatively detailed overview of research on zinc isotopes,including the reference materials and analytical methods of zinc isotopes,the zinc isotope compositions of the main reservoirs in nature,the behavior and fractionation mechanisms of zinc isotopes in different geological processes,and recent advances on zinc isotopes in the four fields of Earth science:(1)tracing the deep carbon cycle,recycled oceanic materials and the origin of compositional transition of alkaline basalts;(2)tracing the sources of ore-forming material,microbial mineralization,and indicating mineral exploration;(3)unrevealing the origin and evolution of the moon;(4)indicating the primary productivity,biogeochemical processes,and the mechanism of the mass extinction at the end of Permian.In the future,with the development of zinc isotope microarea in situ analysis technology,zinc isotopes will be widely used in geosciences,especially in ore deposits,and biomedical sciences.
