Weichselian stratigraphy of sediments from the lower Pechora River
A large section near the village of Hongurei on the Pechora River, ca. 100 km inland from the Barents Sea coast, reveals the following stratigraphic record of the last glaciation: The lowest units are lacustrine silt overlain by fluvial sand. These two units are repeated by glaciotectonic upthrustin...

A large section near the village of Hongurei on the Pechora River, ca. 100 km inland from the Barents Sea coast, reveals the following stratigraphic record of the last glaciation: The lowest units are lacustrine silt overlain by fluvial sand. These two units are repeated by glaciotectonic upthrusting from the NW. On top of this stacked succession is a till where fabric measurements reflect ice movement from the NE. Above the till is a partly laminated glaciolacustrine clay, probably deposited during the deglaciation of the site. We interpret the two ice flow directions to reflect a single ice advance. The Hongurei site is situated on the eastern rim of a marginal lobe of the Markhida moraine complex.
