近十年我国非传统稳定同位素地球化学研究进展

Progress of Non-Traditional Stable Isotope Geochemistry of the Past Decade in China

非传统稳定同位素是过去十年国际上地球化学学科发展非常迅猛的方向,我国科研人员也以自主创新的方式参与到这一前沿研究的大潮中,研究队伍不断扩大,已成为这一学科方向的重要研究力量。本文回顾了过去十年(2010—2020)我国非传统稳定同位素分析技术研发方面的进展,同时对一些重要研究方向的代表性应用研究成果进行了总结。在分析技术方面,我国主要的相关实验室对众多非传统稳定同位素体系的高精度测试技术进行了探索,开拓了一些具备国际先进甚至领先水准的分析技术方法;在应用研究方面,不同的研究团队侧重于各自关注的研究领域和同位素体系,发展进程有所差别,但总体上处于蓬勃发展阶段,上升势头迅猛。有理由相信未来我国的非传统稳定同位素地球化学仍会继续快速发展,技术上会对已有的方法优化提高,并不断开拓新的体系,应用研究上将更深入探索地质、环境过程中的分馏机制,同时将在地球科学的相关研究领域得到更广泛的应用。

As one of the most rapidly advanced branches of geochemistry, non-traditional stable isotope has been explosively developed in the world during the past decade, and Chinese researchers have also participated in a manner of independent innovation in this frontier field. This paper will systematically review the progresses in analytical technologies of non-traditional stable isotope achieved by Chinese research teams from 2010 through 2020 and will also summarize representive achievements of applying these technologies in earth sciences. It will be shown that the Chinese research teams have explored the high-precision analytical techniques in testing isotopic composition for many non-traditional stable isotope systems and have developed some internatioanally advanced or even leading analytical techniques. In terms of research application, different Chinese research teams have focused on different groups of non-traditional stable isotope and have applied their techniques in multiple fields of earth science study. The degree of development is different, but the overall development is in a vigorous and rapid development stage. There is reason to believe that non-traditional stable isotope geochemistry in China will continue to develop rapidly in the future, the existing methods will be optimized and improved, and new non-traditional stable isotope systems will continue to be developed. These methods will aid in studying a broader range of earth sciences and facilitate interdisciplinary researches. The mechanisms of the non-traditional stable isotope fractionation during various geological processes will be deciphered more clearly, and their applications will be more spohisticated.
