镁(Mg)是主要造岩元素,其地球丰度仅次于铁和氧。Mg几乎参与了地表所有圈层间的物理、化学和生物作用。随着多接收器等离子质谱等分析方法的改进和完善,Mg同位素显示出更加广阔的应用前景。同时,Mg独特的地球化学特征,使其在地表及海洋地球化学领域的应用日益广泛。本文主要就近几十年来Mg同位素在地表及海洋地球化学领域的研究现状、存在的问题以及发展趋势进行系统的总结与探讨。虽然,目前对Mg同位素的研究还处于早期阶段,但许多研究成果显示,Mg同位素具有很大潜力成为环境变化的新的指示工具。 |

Magnesium, whose Earth abundance is in the third place only after oxygen and iron, is one of the major rock forming elements. Magnesium takes a part in, almost, all geochemical, physical and biological processes of different spheres. Given rapid improving of analytical method of the multiple collector inductively coupled plasma mass spectrometry (MC ICPMS), Mg isotope will be used in a broad range of geochemical applications in the near future. Due to its distinct geochemical characteristics, Mg has been successfully demonstrating wider application perspectives in Marine and Earth Surface Environments. This paper reviews the recent progress of Mg stable isotope studies. In addition, existing problems and development tendency are also discussed. Regardless of its early stage, the most recent researches have shown that Mg isotopes are potential indicators of environmental changes. |
