Thermal subduction of young oceanic crust could provide the necessary thermodynamic conditions for melting of subducted sediments and the slab in a shallow, high-temperature environment. We therefore hypothesize that the formation of the Zuozuo late Jurassic high-mg diorites is related to the initial subduction of the Meso-Tethys oceanic crust.
