Abstract
Cold slabs can take water into the transition zone. Stored within Ringwoodite and Wadsleyite Excess water may predict locations of enigmatic intraplate volcanism Predict influx of water from cold, wet slabs by fusing plate reconstructions and thermodynamics Water reservoirs in sediments, crust, lithospheric mantle But how do we validate this against observations? Various global tomography models resolve the MTZ. Temperature and water are strongly correlated A region of high temperature looks like high water in tomography Vp /Vs ratio from GYPSUM
