Ultra-low-velocity anomaly inside the Pacific Slab near the 410-km discontinuity
Abstract The upper boundary of the mantle transition zone, known as the “410-km discontinuity”, is attributed to the phase transformation of the mineral olivine (α) to wadsleyite (β olivine). Here we present observations of triplicated P-waves from dense seismic arrays that constrain the structure o...
