Integration of lithostratigraphic, magmatic, and metamorphic data from the Lhasa–Qiangtang collision zone in central Tibet (including the Bangong suture zone and adjacent regions of the Lhasa and Qiangtang terranes) indicates assembly through divergent double sided subduction. This collision zone is characterized by the absence of Early Cretaceous high-grade metamorphic rocks and the presence of extensive magmatism with enhanced mantle contributions at ca. 120–110 Ma. Two Jurassic–Cretaceous magmatic arcs are identified from the Caima–Duobuza–Rongma–Kangqiong–Amdo magmatic belt in the western Qiangtang Terrane and from the Along Tso–Yanhu–Daguo–Baingoin–Daru Tso magmatic belt in the northern Lhasa Terrane. These two magmatic arcs reflect northward and southward subduction of the Bangong Ocean lithosphere, respectively. Available multidisciplinary data reconcile that the …
