Abstract

Lake Taymyr is largest lake in Eurasian Arctic. Late Quaternary environmental history of the area has been studied extensively during the last decades. However, Late Pleistocene and Holocene history of Lake Taymyr itself remain uncertain. More information concerning lake-level changes and climate conditions can be obtained by studying lake terraces. During summer 2016, several outcrops of Lake Taymyr terraces (10-m high and 25-m high terraces) deposits have been investigated. Here we present the results of lithological, palynological study, and dating of studied outcrops. Paleoenviromental conditions and lake-level changes during Late Pleistocene and Holocene are reconstructed based on obtained results. 25-m terrace attributed to Late Pleistocene and associated with cold and relatively shallow marine environment. The age of terrace is not yet determined. The studied 10-m terrace deposits accumulated within the time interval from 6.5 to 5 cal. kyr BP and marks lake-level position 8-10 m higher than modern. Pollen analyses reflect the typical conditions for the terminating part of the regional Holocene Climate Optimum.
