摘要：
137Cs and 210Pb based sediment chronology methods, along with an HPGe gamma-ray spectrometry system, were applied to estimating of sediment accumulative rates (SAR), sedimentation rate (SR) and sedimentation chronology in the Anzali Lagoon. Sedimentation chronology was calculated according to the 210Pbex based-models including; the constant rate of supply, constant initial concentration and 137Cs peak-technique. The SAR value were ranged from 0.12 g cm−2 year−1 in core-2 to 0.21 g cm−2 year−1 in core-3. The results showed that the average of SR and SAR values after 1986; interval were 22% and 54% more than between 1963 and 1986 intervals.
