Abstract Subduction transports oxidized material into Earth’s interior. The Mariana subduction zone is a representative example of modern plate tectonic regimes and provides a comprehensive set of geological, geochemical and geodynamical data. Here we use thermomechanical–thermodynamic numerical methods to simulate redox dynamics and fluid-melt release along a Mariana-type subduction setting in two dimensions, allowing comparison between our model and long-term oxidation events in the Mariana arc.
