Distribution of the Thickness of Quaternary Sediments and Principal Features of the Pre-Valdai Surface in the White Sea

摘要

Friable sediments of different glacial and intergla-cial epochs are abundant in the White Sea and adjacent land areas influenced by Pleistocene glaciations. Numerous studies carried out in neighboring areas of the Kola and Kanin peninsulas and Karelia provide grounds to conclude that glacial-periglacial sediments represent a substantial constituent of Quaternary sequences. Most of the land areas surrounding the White Sea have been studied thoroughly. Detailed paleogeographic maps of the region were compiled, and analysis of its Late Cenozoic evolution was presented based on generalization of the available geomor-phological, lithofacies, and geological-geophysical data.
