Investigating Holocene mountain glaciations: a plea for the supremacy of glacial geomorphology when reconstructing glacier chronologies

Investigating Holocene glacier chronologies constitutes a valuable approach within palaeoclimatic research. Recent progress of numerical dating techniques, in particular terrestrial cosmogenic nuclide dating (TCND), has given it new momentum. Highly increased precision and improved methodological procedures of data calibration seem, however, to have gradually pushed previous rigorous geomorphological analysis of the investigated glacier forelands aside. By using a well-known key site in the Southern Alps/New Zealand it is demonstrated that even alleged benchmark studies are not immune to geomorphological uncertainties. Considerable potential misinterpretations are alerting and reinforce the demand for an unaltered ‘supremacy’ of geomorphology in this context. Especially with global compilations aiming at wider palaeoclimatic conclusions critical re-assessment of glacier chronologies may occasionally seem necessary.

调查全新世山地冰川:重建冰川年代学时对冰川地貌至高无上的恳求

调查全新世冰川年表是古气候研究中的一种有价值的方法。数值测年技术的最新进展,特别是陆地宇宙成因核素测年(TCND),赋予了它新的动力。然而,数据校准的高度提高的精度和改进的方法程序似乎逐渐将先前对所调查冰川前地的严格地貌分析搁置一旁。通过使用南阿尔卑斯山/新西兰著名的关键地点,可以证明即使是所谓的基准研究也不能免受地貌不确定性的影响。在这种情况下,相当多的潜在误解正在提醒并加强对地貌学“至高无上”的需求。
