330 _aThe paper presents the first set of micropaleontological data from the Buor-Khaya Bay sediments in the southeastern part of the Laptev Sea, obtained from the bottom sediments through permafrost drilling. The study of diatoms and spore-pollen assemblages in Hole 1D-11 and Hole 4D-12, high-resolution seismic profiling, and lithological composition of the sediments have facilitated the identification of two different age strata formed under different conditions and dating to the Late Pleistocene and Holocene. The Pleistocene strata were composed of assorted sands with inclusions of dense dehydrated silt formed under continental conditions. The Holocene strata were composed mostly of clayey silt that had formed under transgressive conditions and significant influence of the Lena River runoff and Arctic tundra vegetation on the coast.
