Age of the «cross-laminated sandy» stratum from the reference section Yar Sredny (Central Kamchatka) according to the paired 230Th /238U and 14C dating of peat
For the first time, numerical radioisotope age were obtained for the “cross-laminated sandy” stratum, which is widespread in Neopeopleistocene reference sections of loose sediments from Central Kamchatka. Two peat layers, incorporated in the “cross-laminated sandy” stratum of the Yar Sredny, were studied. The results of their paired 230Th/238U and 14C dating are in good agreement with each other. According to the dating results, it was determined that the “cross-laminated sandy” stratum was deposited, apparently, in the range of about 50-40 thousand years ago, i.e. in the Late Pleistocene (MIS-3), and not in the Middle Pleistocene, about 400-300 thousand years ago, as previously thought.
