The radionuclides thought of for dating are 210Pb and 226Ra. The surplus 210Pb (210Pbex) exercise is calculated because the distinction between the total 210Pb and also the fraction in equilibrium Along with the guardian radionuclide 226Ra. Calculations for the chronology of the sediment layers ended up carried out utilizing the mass depth (g cm?2)
