Frictional heating is likely to occur along the boundary between the subducted plate and the overlying mantle wedge. Flux melting of either the subducted lithosphere or the overlying mantle wedge could occur as a result of the release of volatiles as the subducted plate heats and metamorphoses producing water and/or carbon dioxide fluids.
