Discovery of radiolaria from Upper Cretaceous Oceanic Red Beds in Daba, Kangmar and its paleogeographic implication

► We carry out radiolarian biostratigraphic study about the CORBs in Tibet. ► Occurrence of the radiolarian assemblages indicates a Campanian age of the CORBs. ► Discovery of radiolarians contributes to Cretaceous paleogeographic interpretation.
