| Abstract: | This paper obtained the data of the cores based on U-series age from ZK02 borehole at ridge of Dalangtan in the western Qaidam basin,where 34 samples from the sludge containing gypsum silt were selected of select for 130 ka BP(90.5 m and above) and the pollen analysis was done.Based on the pollen characteristics,the assemblage of the pollen from the bottom upwards can be divided into six zones to analyze the ancient vegetation succession in the last interglacial(130 ka BP) state in this area.The results sho... |
