The Quaternary geology map was created for the Yana-Indigirka (eastern part) and Kolyma lowlands, tundra and partly forest-tundra zones. The map corresponds to the nomenclature sheet of Government Geological Map R-(55)-57, northern part. The primary goal for creating the map is to enhance current knowledge of Quaternary deposits distribution in Yedoma regions in North-Eastern Siberia due to the lack of the geological maps of large scale for this region. For most area of the region maps of 1:200.000 scale are still not created and only geological maps of 1:1.000.000 scale exist. The Database of Quaternary Deposits from Maps of 1:1.000.000 scale, East and Central Siberia, is available via https://apgc.awi.de (Bryant et al., 2017, https://doi.org/10.5066/F7VT1Q89). The main Quaternary deposits on the Yana-Indigirka and Kolyma lowlands are late Pleistocene ice-rich Yedoma Ice Complex (LIII2-4), corresponded to yedoma uplands, and Holocene Alas Complexes (lbIV) formed in drained thermokarst lake basins (alases) ...
