| 摘 要： | 非质量硫同位素分馏效应是目前国际上最前沿的稳定同位素地球化学研究领域之一。在简要介绍非质量分馏理论的基础上,对近几年非质量硫同位素分馏效应的最新研究成果进行总结和分析。关于非质量硫同位素分馏的微观来源机制存在较多争议,有待于进一步探索;采用SF6为工作气体是现有硫同位素高精度测定的主要制样技术;非质量硫同位素分馏效应研究为火星大气演化及火星生命痕迹探询、古代大气氧化条件、地球早期硫循环、火山活动对气候的影响等重大地质科学问题的解释开辟了一条独特的新途径。最后对非质量硫同位素分馏领域研究趋势进行了探讨。

| Abstract: | The research on mass independent sulfur isotope fractionation is one of the advancing fronts in stable isotope geochemistry.Based on brief introduction of related theory,the recent progress in mass independent sulfur isotope fractionation is summarized.The micro origin mechanism of mass independent sulfur isotope fractionation is still controversial;taking SF6 as the working gas is the main preparation technology for high precise measurement of sulfur isotope composition;the study on mass independent sulfur isotope fractionation provides new approach to explain many important geologic events,which include atmospheric evolvement and possible biological activity exploration of Mars,primordial atmospheric oxidizing condition,primordial sulfur cycle of earth,effect of volcanic activity to climate,and so on.Finally,the further research trend of mass independent sulfur isotope fractionation is discussed. |
