Ancient exhumed planation surfaces at the Kola Peninsula

Abstract

Present-day topographic surface of NE Baltic shield includes some heterogeneous and heterochronous topographic elements; some of them are dated back to Pre-Cambrian and have been recently exposed due to erosion of the overlying members. «Exhumation» of the ancient planation surfaces was of great importance in the evolution of the Baltic shield and probably other shields as well. In this connection a historical and genetic analysis of such areas requires the relict landforms to be identified and their genesis and evolution investigated.
