A breakthrough study reveals that low-velocity zones (LVZs) beneath tectonic plates originate from water-rich material rising from Earth’s mantle transition zone (410–660 km depth). Published in National Science Review, the research combines geodynamic modeling and seismic data to show how subduction drives this hydrous upwelling, causing melting that forms LVZs. This process facilitates global water recycling between Earth’s surface and deep interior, reshaping understanding of plate tectonics and mantle evolution.
