Biomarker and pollen in core SG-1 from Tibetan Plateau spanning the Mid-Pleistocene Transition
Paleohydrological data comprising pollen assemblages and leaf-wax hydrogen isotopes (δDwax) from paleolake sediments in the Qaidam Basin (China) provide evidence for a link between increased moisture availability on the Tibetan Plateau and global cooling during the Mid-Pleistocene Transition.
