A 7. m sediment core from the Bayan Tohomiin Nuur dry lake located in southern Mongolia was investigated by a multidisciplinary study to reconstruct the history of climate and paleoenvironmental conditions during the late Quaternary. The geochemical, granulometric, palynological and ostracod results show a graduation of at least nine climatic units during the last 15. ka. cal. BP. The climate during the late Glacial changed from wet towards more dry conditions, representing the beginning of the Younger Dryas period. At 11. ka. cal. BP a rise in temperature and precipitation could be reconstructed, marking the onset of the Holocene. The humid period of the Holocene lasted until about 4. ka. cal. BP, interrupted by shorter dry/cold reversals at 8.5-7.5. ka. cal. BP and 5-4.5. ka. cal. BP. The aridity in southern Mongolia increased afterwards accompanied by the strengthening of aeolian processes, dune remobilization and lake desiccation.

Funding Information: We thank the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) for funding of the project’Late Pleistocene, Holocene and ongoing geomorphodynamics in the Gobi Desert; South Mongolia’ (LE 730/16-1). Field work was supported by the Mongolian Academy of Sciences (Prof. D. Dorjgotov, A. Tschimegsaichan). Palynological analyses and datings were financed by a scholarship from the Kohat University of Science and Technology, Pakistan, to Waheed Murad. We especially thank Serd-Yanjiv Narangerel for help during field work. The AMS analyses were carried out by the AMS 14 C Laboratory of the University Erlangen.
