Reconstruction of the relative level of the White Sea during the Lateglacial – Holocene according to lithological, diatom analyses and radiocarbon dating of small lakes bottom sediments in the area of the Chupa settlement (North Karelia, Russia)

New lithological, palinological and chronological data received as a result of studying the bottom sediment of small lake depressions for the area of the Chupa settlement situated on the Karelian Coast of the White Sea have been presented. Complex studying of bottom deposits of lakes located on different elevation have allowed to establish time and features of their sedimentation and to construct the relative sea-level curve for the Lateglacial and Holocene for the Chupa are

Postglacial uplift of the Earth crust in the North-Western part of the Kola region

The new lithological, micropaleontological and chronological data received as a result of studying the lake bottom sediments sequences in a valley of the Tuloma River have been presented. Investigation of lakes situated in different areas of the Tuloma River valley at different elevations and their correlation with position of ancient marine coastal lines and forms has allowed recognizing the character of sedimentation and specific of neotectonic movements of the Earth's crust in the Late Glacial and Holocene in the North-Western part of the Kola region. The equidistant diagram of relative lines of the Earth's crust uplift has been presented for the studied area. The magnitude of the different-age uplift correlated to these lines, and uplift gradient along the valley of the Tuloma River and Kola Bay of the Barents Sea has been estimate
