Carbon burial in lake sediments is an important component of the global carbon cycle. However, little is known about the magnitude of carbon sequestered in lake sediments over the arid/semiarid region of China (ASAC). In this study, we estimate both organic and inorganic carbon burial since ~ad 1800 based on nine lakes in ASAC, and discuss the most plausible factors controlling carbon burial. Our...
The radioactivities of 210Pb and 137Cs have been measured to estimate the dates of the sediments of a surface core (QH0407-C-2) in the northern basin of Lake Qinghai. The sedimentation rate derived from 210Pb radioactivity correlates well with that inferred from 137Cs radioactivity. The dates calculated from depth sedimentation rate (cm/a) are similar to those derived from mass accumulation rate (g...
