THE GEOCHRONOMETRIC AGE OF LATE PLEISTOCENE TERRACES ON THE LOWER YENISEI

Abstract

New radiocarbon-AMS and optically stimulated luminescence (OSL) dates from key sections of postglacial terraces of the Yenisei River near the Arctic Circle demonstrate that the bulk of the Second Terrace alluvium was deposited during the early marine isotope stage 3 (MIS 3) some 45–60 ka BP. The glacifluvial cover of the Third Terrace was formed by melting Putorana glaciers approximately 60–75 ka BP.
