Corresponding author: SHEN Ji (corresponding author), male, born in 1986, associate research fellow in University of Science and Technology of China (USTC). He received his BS and PhD degrees from USTC in 2007 and 2013, respectively. During this stage, his research focused on element and isotope behaviors at a subduction setting. In 2013, he carried on stable Cr isotope research at USTC as a post doctor. In 2016, he became an associate research fellow at USTC. His main research has extended to mechanism of the stable Cr isotope fractionation during different geological processes, and implications for the material recycling in subduction zones, redox conditions for planetary evolutions. So far, he has published more than ten papers in high-level academic journals such as Earth and Planetary Science Letters, Geochimica et Cosmochimica Acta, Geochemistry, Geophysics, Geosystems, and so on.

Abstract

Abstract

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.
