Radiocarbon ages from the organic plant material from the ice wedge surrounding deposits in the 6-8 m Chara River terrace in 1985 and 1988 sampling years.Samples of organic material for radiocarbon age determination have been selected in several parts of 8-m terrace. 14C ages have been obtained in Radiocarbon Laboratory of GIN RAS (L.D.Sulerzhitsky) and in Radiocarbon Laboratory of the Institute of Geology of Estonia (R.A.Rayamyae). The obtained conventional 14C ages were calibrated using the IntCal13 calibration curve after Reimer et al. (2013, doi:10.2458/azu_js_rc.55.16947).
