Mineralogy, zircon U-Pb-Hf isotopes, and whole-rock geochemistry of Late Cretaceous-Eocene granites from the Tengchong terrane, western Yunnan, China: Record of the closure of the Neo-Tethyan Ocean

New data from mineralogy, geochemistry, zircon U–Pb dating, and Hf isotopes have revealed Late Cretaceous to Eocene magmatic intrusions in the Tengchong terrane and constrained the origin, tectonic setting, and characteristics of tin‐bearing and barren granitoids. We divide the studied granitoids into two groups: (a) the Late Cretaceous Zhinaxiang (70 Ma) and Early Paleocene Dazhupeng (65 Ma) S‐type barren granites and (b) the Eocene Lailishan A...
