Abstract

A rough estimate of glacial erosion in the Precambrian basement is related to the total denudation of bedrock since its formation in the Proterozoic. The basis for the calculations is reference to surfaces of different age. Glacial erosion is responsible for merely polishing the northern shields. Major denudation occured during the Proterozoic and amounted to tens of kilometres. During long periods the basement was protected by Paleozoic cover rocks. It was re-exposed successsively during the Mesozoic and Tertiary with denudation amounting to 600 m at the most
