Abstract: This study is a palynological and stratigraphical investigation of E1 and E10 core samples from thesouthern part of Lake Erçek (Eastern Anatolia, Turkey). Core samples were taken by a gravity corer from differentwater depths. Deposits in the core samples include mostly laminated rhythmic sediments, massive and gradedlayers and a tephra layer from E10 core, representing different time spans because of the faulted ground of thelake. Tentative time scales of the core samples are based on pollen and tephra correlation with Lake Van deposits.According to the palynological investigations, palaeovegetation of Greenlandian is represented by Amaranthaceaedominant halophytic vegetation and semi-arid palaeoclimate conditions based on pollen analysis around Lake Erçek.The Meghalayan stage is mainly characterized by Poaceae-dominated steppe vegetation and increasing humanimpact according to anthropogenic pollen indicators. The Meghalayan palaeoclimate of Lake Erçek was more humidthan Greenlandian and is represented by maximum deciduous Quercus expansion in recent times around the LakeErçek area.
