New Parameter Enhances Insights into the Evolution of Mantle's Redox States
Researchers from the Institute of Oceanology of the Chinese Academy of Sciences (IOCAS), together with their collaborators, have recently proposed a new parameter, "potential oxygen fugacity", to directly compare the fO2 characteristics of melts formed ...Also published on EurekAlert! (https://www.eurekalert.org/news-releases/1054393)The oxygen fugacity (fO2) of the mantle controls the speciation and mobility of volatiles within it, influencing the composition of volatiles released during mantle-derived ...
