abstract = "An experimental study, implicated in the revealing of the conditions for the origin for Fe3+-bearing magnesiow{\"u}stite in the lithospheric mantle, was performed using M{\"o}ssbauer spectroscopy of pre-synthesized samples. Experiments were carried out using a multi-anvil high-pressure split-sphere apparatus at 6.3–7.5 GPa, in the range of 1100–1650 °C in carbonate-metal, carbonate–oxide-metal, carbonate-oxide, carbide-oxide and carbonate–metal-sulphur systems. In three experimental series, oxygen fugacity gradient in the samples was created, which enabled the study of the processes of magnesiow{\"u}stite formation under oxidizing and reducing conditions (ΔlogfO2 (FMQ) values from −1 to −5). It was established that Fe3+-bearing magnesiow{\"u}stite can form both in assemblage with oxidized phases, such as carbonate or with reduced ones—metal, carbides, sulphides, graphite and diamond. According to the M{\"o}ssbauer spectroscopy, the composition of synthesized magnesiow{\"u}stite varied within a range of Fe3+/ΣFe values from 0 to 0.3, with IV and VI coordination of Fe3+ depending on P, T, fO2, x-parameters. It was established that Fe3+-bearing magnesiow{\"u}stite formation processes under upper mantle P,T-conditions include redox reactions, with magnesiow{\"u}stite being (1) reductant or (2) product of interaction, (3) crystallization processes of magnesiow{\"u}stite from an oxidized melt, where magnesiow{\"u}stite acts as a sink for ferric iron and (4) iron disproportionation.",

In three experimental series, oxygen fugacity gradient in the samples was created, which enabled the study of the processes of magnesiowüstite formation under oxidizing and reducing conditions (ΔlogfO2 (FMQ) values from −1 to −5). It was established that Fe3+-bearing magnesiowüstite can form both in assemblage with oxidized phases, such as carbonate or with reduced ones—metal, carbides, sulphides, graphite and diamond.
