Small-scale heterogeneities in the convective upper mantle beneath circum-Pacific subduction zones: evidence for fragments of recycled basaltic crust
S Kaneshima - Physics of the Earth and Planetary Interiors, 2023 - Elsevier
We show evidence for the presence of compositional heterogeneities at 10 km scale in the
convective upper mantle below the circum-Pacific subduction zones. By array-processing …
