Structure of sediments of the final stage of the Kazantsevo transgression (MIS 5) in the north of Western Siberia

Comment on “MIS 5a and MIS 3 relatively high sea-level stands on the Hatay-Samandağı coast, Eastern Mediterranean, Turkey”. U. Doğan, A. Koçyiğit, B. Varol, İ. Özer, A. Molodkov, E. Zöhra. Quaternary International (2012), 262, 65–79

“…Here, they cite a recent paper (Gusev and Molodkov, 2012) on substage 5a whereas a considerable number of papers have previously been published on this period. Among them, the paper by of TIMS U-series coral dates from Barbados is of particular interest since they show that MIS 5a may actually consist of two distinct high stands one of which is Their assertion that, "Shorelines related to other substages of MIS 5 can only be seen in areas with fast tectonic uplift", is not accurate as MIS 5 sea-levels are readily observed at moderately uplifting areas such as Barbados (Broecker et al, 1968;Mesolella et al, 1969;Gallup et al, 1994) and Haiti (Dodge et al, 1983;Dumas et al, 2006).…”

Pleistocene-Holocene Palaeoenvironmental Records From Permafrost Sequences at the Kara Sea Coast (Nw Siberia, Russia)

“…Accumulation of Late Pleistocene sediments in climatic conditions similar or colder than present ones, and wide distribution of polygonal ground ice exclude the presence of large ice sheet in the north of West Siberia [Svendsen at al., 2004]. There is evidence of marine conditions in the lower Yenisey River during the entire MIS5, which excludes the glaciation around 90 kBP [Gusev and Molodkov, 2012]. Such contradictions in currently existing models of development of northern West Siberia in the Middle-Late Pleistocene indicate the need for a more detailed comprehensive study of Quaternary deposits and ground ice sediments of the North.…”
