Schematic illustration of FeO and SiO2 compositional profile and diffusion-induced Fe isotope fractionation of interfacial melt during the convective growth of an ascending Si-melt.
57FeO or 54FeO line represents a hypothetical diffusional profile for the corresponding pure FeO isotope endmember. The thickness of the interfacial melt is exaggerated for illustration purpose. See text for details.
