Effects of water on high-pressure transformation kinetics and the metastable mineralogy in subducting oceanic plates

Oceanic plates descend into the Earth's deep interior as cold currents of mantle convection, and largely deform in the mantle transition zone at 400-800 km depths. The present study was intended to experimentally reveal phase transformations and plastic deformation of the plate materials, those are key processes affecting the plate dynamics. Mineralogy, density, viscosity, and water content were constrained based on the experimental results obtained, and those effects on the mantle convection were discussed.
