On the erosion of Pleistocene glaciers at the Kola Peninsula

Abstract

The author analyzed spatial distribution of marks of glacial erosion (striation, scratches and grooves on solid rock surface) and Pre-Pleistocene crust of weathering, the former appeared to be mostly located at the Kola Peninsula peripheral parts (North-West and the Kandalaksha coast in particular), the latter is restricted to inner uplands of the peninsula, mostly at 180-300 meters a. s. l. Glacial plucking had not affected considerably the Kola Peninsula relief. During the last glaciation an autonomous ineffective Kola ice sheet existed here, an outlet glacier of the Scandinavian ice sheet being restricted to North-West Murmansk region.
