摘要
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.
