Serpentinite dehydration is essential for water recycling in subduction zones, the released fluids are considered to be a critical component in the oxidation of the sub-arc mantle. However, whether the serpentinite-derived fluids are oxidized or reduced remains hotly debated.

A research team led by Prof. Zeng Zhigang from the Institute of Oceanology of the Chinese Academy of Sciences (IOCAS), together with co-researchers from Tianjin University and the Guangzhou Institute of Geochemistry of CAS, has revealed that a sub-arc mantle from cold subduction zones can be metasomatized by serpentinite-derived sulfate-rich fluids.
Relevant results were published in Journal of Geophysical Research: Solid Earth on Oct.
