Sedimentation Rates Dating


Sedimentation rates and dating of bottom sediments in the ...

Sedimentation rates and dating of bottom sediments were estimated in two sampling stations of the Gulf of Gdańsk and in four stations in the open sea area. Estimations were based on vertical distributions of 210Pb, 137Cs and 239,240Pu activity concentrations in sediment core samples taken in 1998–2007.

In combination of the 210 Pb and 137 Cs dating results and historical data, we found that the modern sedimentation rates in different sediment cores (except FX6) of Fuxian Lake had a similar tendency, which can be marked off three stages: natural evolution stage, man-made disturbances stage and man-made transformation stage.

Methods to provide accurate accumulation rates for lake models are discussed. Cores were taken in 1979 in two basins of Lake Lucerne, Switzerland, and accumulation rates were calculated by using Pb-210 dating and by a natural landslide marker of 1795 in one basin (Weggis). In the other basin (Horw Bay) the sediment accumulation rates based on the lead method were compared with yearly ...
