Application of Monte Carlo-type modeling method to estimate 210Pb errors in dating of peat deposits of the European subarctic of Russia (on the example of Arkhangelsk region)

210Pb dating is а key method for studying sediments and peat deposits in the anthropocene, applicable in the time range of 100-150 years. Monte Carlo simulation was used to estimate 210Pb dating error. The approach is implemented in the format of MS Excel spreadsheets, in which the calculated parameters are core diameter, half-life of 210Pb, layer depth, dry weight, total content of 210Pb and concentration of 226Ra. The approach was tested when dating peat cores selected in the Primorsky and Mezensky districts of the Arkhangelsk region, followed by calculation of sedimentation rates.
