Composition, Age, and Origin of Ordovician-Devonian Tanjianshan granitoids in the North Qaidam Orogenic Belt of northern Tibet: Implications for Tectonic Evolution

Chenghan Xu, Fengyue Sun, Xingzhu Fan, Lu Yu, Depeng Yang, Shahzad Bakht & Dongqian Wu
The North Qaidam Orogenic Belt (NQOB) is characterized by widespread Palaeozoic magmatism and high to ultrahigh-pressure metamorphism that provides important information regarding the continental crust growth and tectonic evolution in the North Qaidam. Our work focuses on the geology, geochronology, whole-rock geochemistry, and Sr–Nd isotopy of granitoids in the Tanjianshan area in the northern NQOB. The results indicate that the 486–469 Ma adakitic and TTG-like granitoids originated from the partial melting of Middle–Late Mesoproterozoic lower...
