Solubility of Os and Ir in sulfide melt: Implications for Re/Os fractionation during mantle melting
Although both rhenium (Re) and osmium (Os) are highly siderophile elements (HSE), they show contrasting geochemical behaviors during partial melting of the mantle - Re is mildly incompatible whereas Os appears to be compatible. This fundamental difference, unique among commonly used isotopic chronometers, causes large variations of Re/Os in oceanic basalts. However, which mantle phases control the geochemical behavior of these elements during partial melting is controversial. Sulfide is...[Show more]
