Inference on Water Content in the Mantle Transition Zone Near Subducted Slabs From Anisotropy Tomography

We examine the patterns of radial anisotropy in global tomography images of the mantle transition zone near subducted slabs in the western Pacific. Fast SV velocity anomalies are observed in this region, which are compatible with anisotropy due to lattice‐preferred orientation in wadsleyite. Using m...
