Fig. 10From: Subducted oceanic crust as the origin of seismically slow lower-mantle structuresS/P plotted against radius, where S/P is the ratio RMS δ lnVs/RMS δ lnVp. Model slices are taken along the same longitude as Pacific mantle segments in previous plots except they are centered at 15∘ latitude where P-wave coverage is higherBack to article page
