Ivantsevo section of the buried Middle and Late Pleistocene lake-bog deposits near the town Dmitrov, Moscow region

The Ivantsevo section is located in a gravel pit at an outskirt of Dmitrow town, Moscow region. The section consists of sand, peat, gyttia, and silt; cryogenic structures including ice wedge casts are well developed. Repeatedly lake-bog sedimentation changes were observed there. The lake-boggy unit has been formed during MIS 5 since MIS 5e, it includes 3–4 warm intervals. The peat yields fossil insects (mainly beetles), small freshwater invertebrates, and plant macrofossils. Carpological remains include some typical for Mikulino interglaciation species. Pollen record allow recognizing the vegetation changes from mixed pine-birch with single broad-leaved trees to coniferous forests and open communities dominated by birch, shrubs, light-demanding grasses, and Artemisia. The section allows to reconstruct the history of the climate and environment from the Middle Pleistocene (Moscovian Dnieper glaciation) to the early stages of the Late Pleistocene.
