英文摘要	It is not clear how the Asian monsoon evolved after leaving the spatial range of the Intertropical Convergence Zone in the Late Eocene and before the modern-like Asian monsoon formed at similar to 26 Ma. In this study, the results of a well-dated, robust, and continuous paleoenvironmental carbonate oxygen isotope record from the Tuotuohe section in the Tuotuohe Basin on the central-northern Tibetan Plateau indicate that the carbonate oxygen isotope showed positive bias at 30.5 Ma. Evidence concerning the temperature, precipitation, paleolatitude, paleoelevation, salt mines and global temperature changes at this time suggest that the positive oxygen isotope shift was mainly due to a combination of the intrusion of the Indian monsoon into the basin and increased evaporation, both of which were ultimately induced by the tectonic uplift of the Tuotuohe Basin before 30.5 Ma and the retreat of the Paratethys Sea after the Eocene. Carbonate oxygen isotope in the Tuotuohe Basin has an evident positive shift at 30.5 Ma The Indian monsoon intruded into the Tuotuohe Basin at 30.5 Ma The intrusion of the Indian monsoon mainly induced by the tectonic uplifts of the Tuotuohe Basin before 30.5 Ma
