In a study published in Proceedings of the National Academy of Sciences, Prof. Xiao Yilin's group from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) quantitatively determined, for the first time, the chemical composition of supercritical fluids in deep subduction zones. Through 3D imaging modeling of ultrahigh-pressure (UHP) multiphase fluid inclusions, they revealed the important role of supercritical fluids in the cycling of carbon and sulfur in subduction zones, which is of great importance for an in-depth and systematic understanding of the role of supercritical fluids in nature.
