The radionuclides viewed as for dating are 210Pb and 226Ra. The surplus 210Pb (210Pbex) action is calculated because the difference between the whole 210Pb along with the fraction in equilibrium with the guardian radionuclide 226Ra. Calculations to the chronology on the sediment levels ended up executed utilizing the mass depth (g cm−2) to account to the compaction in the sediment layers (Cutshall et al., 1983).
