摘要：
The source of endogenic organic and inorganic carbon in lacustrine sediments is the dissolved inorganic carbon (DIC) in the lake water. The relation between the radiocarbon levels of DIC in Lake Kinneret and of CO2 in the atmosphere has been investigated. The ratio of the former to the latter was found to be 0.814 +/- 0.013. This ratio is used for calibrating the age of the sediment according to the natural fluctuations in the atmospheric levels of C-14 that occurred during the past 10,000 years.
