英文摘要	Pollen concentration (PC) has rarely been used to assess long-term paleoclimate (for example over the Miocene period), vegetation production, sedimentary environment or other factors, particularly for the Tibetan Plateau. In the western Qaidam Basin, on the northern Tibetan Plateau, PCs covering the period similar to 18-5 million years ago (Ma) were calculated and interpreted in terms of the underlying driving forces. The results show that the PCs of the most xerophytic taxa remained stable, while all coniferous taxa decreased during similar to 18-10 Ma. We attribute this phenomenon to continuous aridification, and argue that global cooling played a key role. During similar to 10-5 Ma, the PCs of all taxa increased rapidly, which is contradictory to the continuous aridification after 10 Ma in the western Qaidam Basin. The Tibetan Plateau tectonics around similar to 10-5 Ma caused a change in the sedimentary environment and consequently played an important role in the increase in PCs after 10 Ma. Thus the PC can be a useful proxy for investigations into long-term paleoclimate and tectonics on the Tibetan Plateau. (C) 2016 Elsevier B.V. All rights reserved.
