Sandstone provenance and tectonic evolution of the Xiukang Mélange from Neotethyan subduction to India-Asia collision (Yarlung-Zangbo suture, south Tibet)
Xiukang Mélange contains sandstone blocks derived from both India and Lhasa terrane. Xiukang Mélange evolved during both Cretaceous subduction and Paleocene collision. Asian active margin was largely erosional but partly accretional in Late Cretaceous.
