Arc magmas sourced from mélange diapirs in subduction zones

HR Marschall, JC Schumacher - Nature Geoscience, 2012 - nature.com
At subduction zones, crustal material enters the mantle. Some of this material, however, is
returned to the overriding plate through volcanic and plutonic activity. Magmas erupted …
