Metasomatism and Melting of Cordilleran Lithosphere Resulting From Sediment Relamination During Shallow Subduction

Abstract Mantle xenoliths recovered from the modern backarc region of the northern Altiplano Plateau record metasomatism by slab‐derived silicic melts, and a suite of Quaternary volcanics suggest that melting of accreted crustal material has persisted since shallow subduction in the Oligocene. Xenol...
