Several possible millennial‐scale dry and cold oscillations characterized possibly by C4 plants, or by more positive organic δ 13 C values during the period when C3 plants dominated, are cautiously and tentatively interpreted as showing a similarity with Heinrich events and other cold millennial‐scale oscillations evidenced from a Greenland ice core and Chinese stalagmite. We demonstrate that bulk organic δ 13 C records of sedimentary sequences in the study region have potential for indicating the changes in vegetation composition that were closely associated with climate variation during the last glacial period.

Bulk organic δ 13 C values of sediment sequences are commonly used to indicate past climatic changes, although the causes and mechanisms leading to the observed organic carbon isotope responses are presently not fully understood.
