GLACIAL AND INTERGLACIAL EROSION IN SCANDINAVIAN MOUNTAINS IN A W-E COMPARISON INCLUDING AN APPROACH TO A QUANTITATIVE CALCULATION

The different results of glacial erosion between west and east in Scan dinavia are well known. This difference is described (maps 1 and 2) an d evaluated. The difference includes fjords and lakes, sounds inside h igh islands, trough valleys, glacial cirques, and the strandflat as cr eated by joint action of glacial dissection and marine abrasion in col d interglacials and interstadial periods. An important part is an appr oach to quantitative calculation of lost rock (in km(3)). The calculat ions are made for the groups of glacial and interglacial forms. The ra nking list for lost bedrock is topped by fjords and through valleys. T he total figures for lost rock are compared with similar figures for t he Sognefjord basin. They are of the same order of magnitude in spite of different calculation methods. The relative chronology and problems still remaining for further studies are briefly commented.
