英文摘要	The generalized geologic section of the Kysyl-Syr dune massif (tukulan) in the lower Vilyuy river basin (Central Yakutia) on the basis of new 14 C dates from 27 samples and biostratigraphic data allowed new insights about the Late Quaternary evolution of paleogeographic conditions of dune-forming processes in the region. Based on the previously published results of the studies of key-sections of dune sediments in different parts of Central Yakutia and new absolute age dates, the authors have concluded that the widespread in Central Yakutia dune sediments (D’olkuminskaya series) formed at different hypsometric levels (river terraces, watersheds) over a time spanning from the latest Karginsky termochrone (late MIS-3) till the beginning of the Holocene (between 35 and 10 kyr) under conditions of severe desiccation and desertification of the area. The dune stabilization by soil-vegetation cover occurred during the Boreal optimum of the Holocene (12–6 kyr). The modern dune massifs are interpreted to have formed no more than 1 thousand years ago, which is associated with climatic events of the Little Ice Age. © 2018 Academic Publishing House Geo.
