Abstract

The first Reviews in Mineralogy volume on the Geochemistry of Non-Traditional Stable Isotopes was compiled before it was appropriate to include a chapter on mercury (Hg) stable isotope geochemistry. At that time there were only a few papers on this new topic (Jackson 2001; Lauretta et al. 2001; Hintelmann and Lu 2003), and there were still some important analytical issues that needed to be resolved. But the field has come a long way in a decade. Now we have a different problem; at our last count there were well over 100 publications utilizing mercury stable isotopes and it is becoming very difficult to synthesize this vast amount of exciting and rapidly developing research. Experimental studies have expanded our knowledge of the mechanisms of mercury isotope fractionation and applications of mercury isotope measurements have touched virtually every area of research in mercury biogeochemistry. There have been a number of previous reviews of the mercury stable isotope literature as it has developed (Ridley and Stetson 2006; Bergquist and Blum 2009; Yin et al. 2010; Blum 2011; Hintelmann 2012; Blum et al. 2014). It is our view that the field has become too large to comprehensively review the entire literature on mercury stable isotopes. Ten years ago Hg isotope researchers were just beginning to explore the boundaries of natural Hg isotope variation and the mechanisms that cause this variation in the environment. At that time large and relatively easily measured isotope signals were of great interest and mercury isotope researchers were beginning to develop theories to explain mass dependent isotope fractionation (MDF) and mass independent isotope fractionation of the odd mass-numbered isotopes of mercury (odd-MIF). More recently researchers have discovered a wider range of types of isotopic variability (even-MIF), some of which are subtle and …
汞稳定同位素分析的最新进展
《矿物学评论》第一卷关于非传统稳定同位素的地球化学是在适当地包括汞(Hg)稳定同位素地球化学一章之前编写的。当时关于这个新课题的论文很少(Jackson 2001;Lauretta et al. 2001;Hintelmann and Lu 2003),还有一些重要的分析问题需要解决。但这一领域在过去十年里取得了长足的进步。现在我们有一个不同的问题;根据我们最近的统计,利用汞稳定同位素的出版物超过100篇,要合成这么多令人兴奋和快速发展的研究成果变得非常困难。实验研究扩大了我们对汞同位素分馏机制的认识,汞同位素测量的应用几乎涉及汞生物地球化学研究的每个领域。随着汞稳定同位素文献的发展,以前已经对汞稳定同位素文献进行了多次审查(Ridley和Stetson 2006;Bergquist and Blum 2009;Yin et al. 2010;布卢姆2011;Hintelmann 2012;Blum et al. 2014)。我们认为,这个领域已经变得太大,无法全面审查有关汞稳定同位素的全部文献。十年前,汞同位素研究人员刚刚开始探索自然汞同位素变化的边界和导致这种环境变化的机制。当时,较大且相对容易测量的同位素信号引起了极大的兴趣,汞同位素研究人员开始发展理论来解释汞的奇质量数同位素的质量依赖同位素分异(MDF)和质量独立同位素分异(odd- mif)。最近,研究人员发现了更广泛类型的同位素变异(甚至是mif),其中一些是微妙的,而且……

期刊介绍: RiMG is a series of multi-authored, soft-bound volumes containing concise reviews of the literature and advances in theoretical and/or applied mineralogy, crystallography, petrology, and geochemistry. The content of each volume consists of fully developed text which can be used for self-study, research, or as a text-book for graduate-level courses. RiMG volumes are typically produced in conjunction with a short course but can also be published without a short course. The series is jointly published by the Mineralogical Society of America (MSA) and the Geochemical Society.
