Signature of the last shelf-centered glaciation at a key section in the Pechora basin, Arctic Russia

Depositional environments and sea‐level changes deduced from Middle Weichselian tidally influenced sediments, Arkhangelsk region, northwestern Russia

“…Correlation of the Mezen Transgression from the Arkhangelsk region into the Pechora region provides a stratigraphical marker horizon between the two regions. The tidally influenced fluvial deposits in the Pechora region as well as the marine bed at Vastiansky Kon are found below the Markhida till (Tveranger et al 1998;Svendsen et al 2004). In the Arkhangelsk region, marine deposits are placed stratigraphically between the Cape Tolstik and Syomzha Tills.…”

“…11). In the Pechora River Valley, EarlyÁMiddle Weichselian deposits are mainly fluvial Áterrestrial (Mangerud et al 1999;Henriksen et al 2001), but Tveranger et al (1998 described marine sediments, possibly of post-Eemian age in the Vastiansky Kon section. The mollusc fauna is distinctly arctic (Funder, unpublished), and the sediments record a direct transition from till to offshore glacimarine diamicton similar to a deglacial flooding.…”

“…The mollusc fauna is distinctly arctic (Funder, unpublished), and the sediments record a direct transition from till to offshore glacimarine diamicton similar to a deglacial flooding. This unit may therefore represent the earliest phase of the Mezen Transgression, although admittedly the age is not well established and available TL dates gives ages between 148 and 105 kyr BP (Tveranger et al 1998). It has recently been suggested that also other fluvial deposits in the Pechora River valley may show tidal or marine influence and some flooding into the Pechora basin is considered reasonable (Svendsen et al 2004).…”

Intriguing climatic shifts in a 90 kyr old lake record from northern Russia

“…1) is based on a compilation of events found in a number of river bluffs and gravel pits each representing short time-windows in the geological record (e.g. Guslitser et al 1985;Arslanov et al 1987;Tveranger et al 1995Tveranger et al , 1998Mangerud et al 1999Mangerud et al , 2001Henriksen et al 2001;Svendsen et al 2004). The aim of this study was therefore to obtain a continuous palaeo-environmental record for this area covering the last interglacial-glacial cycle, i.e.…”

Eurasian ice‐sheet interaction in northwestern Russia throughout the late Quaternary

“…Given the overall ice flow pattern, we speculate that the sequence at Hongurei might be dislocated from northwest and later that till deposition took place with ice advance from the northeast.
