This review serves as an explanatory note to the sketch map of loessoids, i.e. loess and various loess-like deposits. The map is a byproduct of the ongoing project of Quaternary Map of the Russian Federation, scale 1:2,500,000 in GIS-format. The prim

Because global sea level during the last interglacial (LIG; 130–115 ka) was higher than today, the LIG is a useful approximate analogue for improving predictions of future sea-level rise. Here, we synthesize sea-level proxies for the LIG in the gla

This paper presents new field and laboratory data combined with previously published materials on interglacial sediments underlying two upper tills of northern European Russia and West Siberia. The emphasis is on the structure and chronometric data o

This is a review of previous works on glaciotectonics and recent epeirogenesis of the northern West Siberian sedimentary basin and adjacent parts of the Urals and the Siberian Craton. It is supported by the addition of detailed structural profiles of

This is a synthesis of the glacial history of the northern Urals undertaken using published works and the results of geological surveys as well as recent geochronometric and remote sensing data. The conclusions differ from the classical model that co

This is an overview of glacial features of the Russian Federation from the western border to the Laptev Sea in the form of an explanatory note to the map of ice marginal formations and ice limits 600 to 11 ka old. Attached is a generalized version of

This is an overview of the latest data on the age of topographically expressed glacigenic formations of the Polar Urals obtained by international geological teams by modern dating techniques including optical luminescence, radiocarbon and cosmogenic

The Middle and Late Pleistocene glaciations of northern Eurasia had a great impact on the evolution of the modern drainage system. This paper presents a review and synthesis on the palaeogeography of glacial lakes, their drainage and impact on the re

We describe and discuss the glacial and climate variations in the Polar Ural Mountains in northern Russia over the last 100 000 years. A series of optically stimulated luminescence (OSL) and radiocarbon ages from sediment cores demonstrate that there
