"Average" interdiffusion of (Fe,Mn)-Mg in natural diopside

(Fe,Mn)-Mg interdiffusion has been investigated in single crystals of natural diopside at ambient pressure, high temperatures (900°C to 1240°C) and low oxygen fugacity (pO 2 ≈ 10 −18 atm to 10 −13 atm). Interdiffusion couples were made with polycrystalline ferro-johannsenite thin film (∼ 250 Å to ∼ 500 Å) as the iron and manganese reservoir (Fe/(Fe + Mn + Mg) ∼ 48 …
