Summary: | The investigation of periglacial and related landforms in South Norway is of high interest for exploring timings of deglaciation and to assess their geomorphological connectivity to palaeoclimatic changes during the Late Quaternary and the Holocene. The ice margins of the Scandinavian Ice Sheet during the Last Glacial Maximum (LGM) are fairly well known, the palaeo-ice thickness, however, which can only be estimated by modelling, remains unclear over large parts of Norway owing to rare field based evi-dences. Due to the significant influence of the former horizontal and vertical ice-sheet extent on sea-level rise, atmospheric and oceanic circulation patterns, erosive properties of glaciers and ice sheets, englacial thermal boundaries and deglaciation dynamics, it is crucial to better understand the topograph-ic features of the LGM ice sheet. Despite recent advances, there is a lack of terrestrial evidences from numerical data in South Norway. In this thesis two high-mountain regions and their surroundings in west (Dalsnibba, 1476 m a.s.l.) and east (Blåhø, 1617 m a.s.l.) South Norway were used to reconstruct palaeoclimatic conditions and deglaciation patterns. Terrestrial cosmogenic nuclides (10Be) and Schmidt-hammer exposure-age dating (SHD) have been utilized to determine the surface exposure of glacially transported boulders as well as of boulder-dominated glacial, periglacial and paraglacial landforms and bedrock outcrops. By developing calibration curves at both study sites for the first time, through young and old control points of known age, it was possible to obtain landform age estimates from Schmidt hammer R-(rebound) values. Beside age estimates, the formation and stabilization of those landforms and the involved processes have provided indications about the Late Quaternary and Holocene climate variability and its connectivity to landform development. The first deglaciation chronology for the western study area could be constructed based on 10 Be sur-face exposure ages. Final local deglaciation on the ...
