Abstract

Reports Mossbauer spectra of γ-Fe₂SiO₄, γ-Mg_1.8Fe_0.2SiO₄, β-Mg_1.8Fe_0.2SiO₄, and Mg_0.85Fe_0.15SiO₃ garnet synthesized in equilibrium with excess Fe metal and SiO₂ at high pressure and high temperature in a multianvil press. The ability of transition zone phases to accommodate significant Fe³⁺ in equilibrium with Fe metal implies that, in an isochemical mantle, the f_O2 of the transition zone must be lower than that of the upper mantle. -from Authors
