Abstract
Total organic carbon (TOC) content correlates very well with hydrogen index (HI) in the sediments of RH core in the Zoige Basin. And the del ta(13)C values of TOC become more positive while both TOC content and HI decline, indicating the subaerial exposure or the lake sediments ap proaching to the water level. On the basis of the above, RH core sedim ents are divided into 23 climatic fluctuation stages, including 12 war m-humid stages and 11 dry-cold stages, which on be compared with ocean ic oxygen isotope stages, loess profile and polar ice-core records.
