Chromium element and isotope geochemistry in high temperature systems

In the past two decades, research on stable Cr isotopes, especially the low-temperature redox processes on the earth’s surface, has been greatly developed. However, in the same period, Cr isotope fractionations induced by high temperature systems had been poorly constrained, especially before 2010. With the improvement of mass spectrometry technology and the wide application of the double-spike method, smaller isotope fractionations in high temperature processes can be accurately identified. This review will give a detailed introduction to the distribution behavior of Cr element and Cr isotope fractionation behavior in high temperature processes achieved in recent years, and potential applications, aiming to provide feasible directions for future researches of Cr element and isotope system.
