10 kwi 2024 · This is a critical review of disputable chronostratigraphic results in the Upper Pleistocene of glaciated Russia including the West Siberian and Russian Plains. The main goal is to assess the validity of stratigraphic tools used for long-distance correlation of young sedimentary formations.

Multiproxy evidence suggests extreme warmth and polar amplification during the middle Pliocene, sudden stepped cooling events during the Pliocene-Pleistocene transition, and warmer than present Arctic summers until ~2.2 million years ago, after the onset of Northern Hemispheric glaciation.
28 paź 2016 · The Middle Pleistocene maximum glaciation limits are lost in the east due to the lack of data. Extensive fields of diamictic hillocks and sand-gravel kames are mapped only within the Taz ice limit, especially in the east where Anabar moraines with Precambrian clasts and Putorana moraines with mafic boulders coalesce.
5 paź 2012 · The size, age and dynamics of Pleistocene glaciers, especially ice sheets that periodically covered the northern seaboard of Eurasia, are crucial for understanding the evolution of arctic climates, sea-level changes, the biota and tectonism.
24 maj 2023 · Ongoing speculation regarding the existence of large Late Pleistocene ice masses in Northeast Eurasia reflects the dearth of age constraints on glaciations across this vast region.
1 cze 2004 · The modern chronological concepts of Middle Pleistocene glaciations in northern European Russia are heavily dependent on the official stratigraphic scale of Central Russia, either directly, as in the Arkhangelsk Region of prevailing Fennoscandian glaciers, or in disguise of local startigraphic labels, as in the Timan–Pechora–Vychegda Region ...
16 sie 2019 · These spatial patterns in Late Pleistocene ice extent suggest that glaciation may be initiated in the Pacific region, before spreading to the North Atlantic region.
