文摘
- •
A long (31–11 Ma) stable isotopic section in the southwestern Qaidam basin, northern Tibetan Plateau
- •
~ 20 Ma paleohydrological change is probably associated with early deformation/initial range growth in northern Tibet.
- •
15–14 Ma negative shift of δ18O values reflects topographic growth in catchment regions (Altun and East Kunlun).
- •
13–12 Ma regional aridification was mostly likely caused by moisture blocking effect of growing mountain ranges.
