Geochemical and geochronological characteristics of Late Cretaceous to Early Paleocene granitoids in the Tengchong Block, Southwestern China: Implications for crustal anatexis and thickness variations along the eastern Neo-Tethys subduction zone
Tengchong Block as arc related to Neo-Tethys occurred Late Cretaceous to Paleogene granitoids. Crust-derived rock along Neo-Tethyan arc has different origins during Late Cretaceous to Paleogene. Crustal thickness along the magmatic arc is decreasing from southern Lhasa across EHS to TB at 64 Ma.
