Petrogenesis of the Triassic granitoids from the East Kunlun Orogenic Belt, NW China: Implications for continental crust growth from syn-collisional to post-collisional setting

The Triassic granitoids are widespread in the eastern section of the East Kunlun Orogenic Belt (EKOB) on the northern Tibetan Plateau. These granitoids well record the evolution of the Paleo-Tethys oceans (named as A'nyemaqen Ocean in the EKOB). Our new zircon UPb data together with ages in literature show that these granitoids represent long-lasting magmatism from the early (T1, ~251–248 Ma), middle (T2, ~247–238 Ma) to late (T3, ~234–214 Ma)...
