The investigation of periglacial and related landforms in South Norway is of great interest for exploring the timing of deglaciation and to assess their geomorphological connectivity to palaeoclimatic changes during the Late Pleistocene and the Holocene. The ice margins of the Scandinavian Ice Sheet during the Last Glacial Maximum (LGM) are reasonably well established. Palaeo-ice thickness can, however, only be estimated by modelling and remains uncertain over large parts of Norway due to sparse field based evidence. Because of 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 improve the understanding of the topographic properties of the LGM ice sheet. Despite recent progress, there is a lack of terrestrial evidence in the form of numerical age data from South Norway. In this study 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 studied to reconstruct palaeoclimatic conditions and deglaciation patterns. Terrestrial cosmogenic nuclide (10Be) and Schmidt-hammer exposure-age dating (SHD) have been utilized to determine the surface exposure age 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 it was possible to obtain landform-age estimates from Schmidt hammer R-(rebound) values. In addition, the formation and stabilization of those landforms and the formative processes have provided indications about the Late Pleistocene and Holocene climate variability and its connectivity to landform development.

挪威南部魏克塞尔晚期冰川消融的各个方面：从晚更新世和全新世地貌的表面暴露年龄推断的冰川消融时间、冰盖几何形状和气候变化

对挪威南部冰缘及相关地貌的调查对于探索冰川消退的时间以及评估它们的地貌与晚更新世和全新世古气候变化的连通性具有重要意义。末次盛冰期 (LGM) 期间斯堪的纳维亚冰盖的冰缘已经相当完善。然而，古冰层厚度只能通过建模来估计，并且由于基于实地证据的稀少，在挪威大部分地区仍然不确定。由于前水平和垂直冰盖范围对海平面上升、大气和海洋环流模式、冰川和冰盖的侵蚀特性、冰期热边界和冰消动力学的显着影响，提高对 LGM 冰盖地形特性的理解至关重要。尽管最近取得了进展，但仍缺乏来自南挪威的数字年龄数据形式的地面证据。在这项研究中，研究了挪威南部的两个高山地区及其周边地区（达尔斯尼巴，海拔 1476 米）和东部（布洛霍，海拔 1617 米），以重建古气候条件和冰川消融模式。陆地宇宙成因核素 (10Be) 和施密特锤暴露年龄测定 (SHD) 已被用于确定冰川运输的巨石以及以巨石为主的冰川、冰缘和冰缘地貌以及基岩露头的表面暴露年龄。通过首次在两个研究地点开发校准曲线，可以从施密特锤 R-（回弹）值中获得地貌年龄估计值。此外，这些地貌的形成和稳定以及形成过程提供了关于晚更新世和全新世气候变异及其与地貌发展的联系的迹象。
