Abstract:
... On the basis of multi-proxy analysis on TOC, TN, C/N, organic δ¹³C and grain size, sediment record from Qinghai Lake provides evidences of stepwise-patterned climatic change since 16 ka BP. Results show that Qinghai Lake underwent six environmental stages. From 16.2 to 14.3 ka BP and from 4.0 to 2.1 ka BP, the organic δ¹³C value was controlled by the concentration of atmospheric CO₂. Relative high ...
