Abstract Tectonic transition from post-collision to intraplate settings is a crucial process in orogenic belts. To characterize such a transition in the Chinese Altai, we conduct an integrated study on Permian to Triassic granitoids. Zircon U–Pb dating reveals that the granitoids can be subdivided into two stages: early Permian (291–286 Ma) and late Triassic (216–209 Ma). Granitoids of both two stages exhibit high SiO2, low Mg#, low Cr and Ni contents, and variable Sr–Nd–Hf isotopes, all of whic...
