Petrological diversity of continental arc magmatism evidenced by Triassic magmatic complexes in East Kunlun Orogen.

ABSTRACT: Understanding the petrogenetic relationships among the synplutonic dikes, magmatic enclaves and plutons in subduction zones provides key insights into the petrological diversity of arc magmatism. Here we present an integrated study on the petrology, LA-ICP-MS zircon U-Pb geochronology, whole-rock geochemistry and Sr-Nd-Hf isotopes of Triassic coeval basic-intermediate dikes, mafic microgranular enclaves (MMEs) and their host plutons (gabbrodiorite, granodiorite and monzogranite) in the East Kunlun Orogen, northern Tibetan Plateau, to reveal their magma sources, magmatic processes and dynamic connections. Petrological and chronological studies reveal that these mafic-felsic igneous rocks coexist in space and time, showing imprints of mixing or mingling and similar crystallization ages (ca.
