The influence of tectonics and bedrock topography on the formation of insular heights at Estonia

Abstract

The role of the bedrock topography in the distribution of the Pleistocene deposits within the range of the insular heights is analyzed, the age of Haanja and Otepaa bedrock elevations being defined. Conclusion is drawn that the tectonic movements were not of great importance in the formation of the insular heights and the latter were formed on the bedrock cores between glacier lobes which differed in the rate of ice flow. Thus the bedrock topography was of primary significance, it predetermined debris accumulation both at its proximal and distal slopes under the moving glacier.
