Middle Pleistocene marine deposits on the Kola Peninsula (NW Russia)

The Kola Peninsula and Russian Lapland: A review of Late Weichselian glaciation

“…While sedimentary and dating evidence of two separate till deposits above the Eemian marker horizon across the Kola Peninsula could suggest an oscillating ice margin, the two till units are more widely considered to indicate there were two separate major glacial episodes during the Weichselian (Grave et al, 1964;Nikonov, 1966;Apukhtin and Ekman, 1967;Grave and Koshechkin, 1969;Apukhtin et al, 1977;Svendsen et al, 2004;Demidov et al, 2006;Hughes et al, 2016;Lunkka et al, 2018;Korsakova et al, 2019). Several authors suggest the lower till unit represents an ice mass on the Kola Peninsula during the Early and Middle Weichselian (Fig.…”

“…Several authors suggest the lower till unit represents an ice mass on the Kola Peninsula during the Early and Middle Weichselian (Fig. 11a; Nikonov, 1966;Grave and Koshechkin, 1969;Apukhtin et al, 1977;Svendsen et al, 2004;Lunkka et al, 2018;Korsakova et al, 2019), although the maximum extent and configuration of this ice mass is uncertain. Glaciofluvial sediments above the lower till suggest that the Early-Middle Weichselian ice mass retreated prior to subsequent FIS glaciation during the Late Weichselian, possibly in response to climatic warming during the Ålesund interstadial (Fig.…”

Neopleistocene Deposits in the Kola Region: Stratigraphy and the Key-Sections – A Contribution to the Database of the Quaternary Terrestrial European Stratigraphy (Datestra)

“…The available data from the Kola Peninsula evidence the Neopleistocene (the middle and late Pleistocene in West Europe) stratigraphy record begins here with the Chekalinsky (MIS 9) Horizon [10,11]. The most ancient deposits are known from only one locality.…”

“…1). Palynological proxies and diatom data from the Ponoi Beds indicate a more favorable environment as compared with the modern one [1][2][3][4][5][7][8][9][10][11][12][13][14]. Palaeontological remains enclosed in the Strelna Bed sediments indicate environment conditions close to the modern ones or colder [3,12].…”

“…Fig. 1 shows 10 key-points that have been taken into account [1][2][3][4][5][7][8][9][10][11][12][13][14]. All stratigraphic units correlate with the marine isotope stages (MIS).…”
