Figure 8. Variation of the radiocarbon age of the Belorussian lake sediments and their NRM age as a function of their depth in the N-2 rock column. The NRM age of the Belorussian lake sediments was obtained by correlating the generalized curve with the PSV records of archeomagnetic data available [Daly and Le Goff, 1996], with the records obtained for the sediments in some British lakes [Turner and Thompson, 1982], and with the records obtained for Lake Nautajarvi [Ojala and Saarinen, 2002]. The position of the radiocarbon dating curve is higher than that of the curve for the NRM age of the Belorussian lake sediments.
