摘　　要：近年来多接收杯电感耦合等离子体质谱(MC-ICPMS)的广泛应用以及化学分离技术改善,极大提高了Ni稳定同位素分析方法的精确度和准确度,推进了Ni同位素地球化学的发展。Ni特殊地球化学性质使其成为同位素地球化学前沿领域,并已取得了一系列成果。本文首先介绍了高效、方便的分离纯化流程和高精度、准确度分析测试技术;其次,总结了地球主要储库的同位素分布和组成,结果表明地质样品Ni同位素分馏程度60Ni达到3.5‰。最后,综述了Ni同位素在反演星核形成、演化时间以及示踪源古环境、物质来源等领域的应用。The development of multi-collector inductively coupled plasma mass spectrometry(MC-ICPMS)and the improvement of chemical separation technology,which greatly improved the precision and accuracy of Ni stable isotope analysis methods,promoting the advances of Ni isotope geochemistry.Due to its special geochemical properties,Ni has become the frontier of isotope geochemistry and has achieved preliminary progress.First,an efficient and convenient separation and purification process and high-precision analysis technology were established.Secondly,the isotopic distribution and composition of the main reservoirs in the earth were investigated.The results showed that the Ni isotopic degree of fractionation in geological samples 60Ni reached 3.5‰.Finally,,Ni isotopes have been initially applied to trace the formation and evolution of star nuclei and the source of Ni deposits,and are expected to be applied to trace paleoenvironments,paleo-oxygen events,and surface Ni geochemical cycles in the near future.Finally,we review the recent progress of the systematicsof Ni stable isotope and its applications in the inversion of the formation and evolution time of star core and the tracing of paleoenvironment and material sources.
