| Abstract: | Depositing ages of sediment in Core Ck6 of Qarhan Lake were dertermined by 14C, 230Th and geomagnetic polarity methods. Results of analyses of stable isotopes composition in carbonate and organic matter were used to set up a model of fluctuating paleoclimate (since 750 ka B. P.) consisting of 11 warm and humid stages and 10 dry and cold stages. |
