Genesis and geodynamic process of early Cretaceous intermediate–felsic batholith within the Chem Co zone, western Qiangtang and implications for Bangong–Nujiang Tethyan Ocean subduction

The complex evolutionary history of collision-related suture zones in the western Qiangtang is poorly understood, due to the lack of pivotal magmatic and tectonic records. The Chem Co intermediate-felsic batholith is situated in the westernmost section of Qiangtang, where it intruded into the Upper Paleozoic metamorphic sedimentary series and was cut by Late-Cenozoic active normal faults. Here, we present evidence from field observations,...
