| Abstract: | The sequences of climatic evolution are reconstructed by the analyses of δ13C and δ18O of carbonate from core RM in the Zoige Basin since 140 kaB. P. During the Last Glaciation there existed at least seven warm
climatic fluctuations and five cold events correlated with the records of ice core and deep sea, and during the preceding
last interglacial period there were two cold climatic variations coinciding with the record of ice core GRIP. These results
de-pict climatic instability in east Qinghai-Xizang Plateau over the last interglacial period. In addition, the environmental
proxies of the carbonate content and pigments indicate the similar results to the stable isotope record from core RM.
