Dataset for: Temporal variability of 14C reservoir effects and sedimentological chronology analysis in lake sediments from Chibuzhang Co, North Tibet (China)

The dataset was obtained by lab analyses, from a 5.48 m-long core sampled from Chibuzhang Co, a lake in north Tibet, China, which contained two obvious obstacles: high reservoir effects and age reversals. We confirmed that a relationship bettween reverse ages and mean GS and carbonate contents, indicating temporal changes of 14C reservoir effects involved in carbonate input and meltwater or old material, which was suitable for sedimentological chronology analysis.
