The constraints from deep processes on the porphyry metallogenesis in collisional orogens
碰撞造山带斑岩型矿床的深部约束机制

The Cenozoic collision of the Indian-Asian continents has induced break-off of the subducted slab,the later has in turn triggered underplating of the mantle-derived magma,partial melting of the lower crust and production of the Gangdese batholiths belt and the co-batbolithic porphyries.In this process,the underplated mantle-derived magma,the remnant from partial melting of the lower crust and the sinking mafic blocks differentiated from the crust composed the thickened marie lower crust.Due to cooling of th...
