摘要

了解基岩属性如何影响高山景观的山谷形成过程是一个突出的挑战。一种多方法的方法被用于统一量化结晶基底岩石的断层频率、方向和岩石硬度,以评估它们对塑造瑞士阿莱奇冰川山谷的侵蚀过程的影响。我们展示了由该地区继承的碰撞框架所施加的断层频率和方向的变化如何控制山谷的局部可蚀性,从而影响山坡和河道的侵蚀过程。我们的研究结果强调了构造预调节如何对山链的侵蚀效率施加一级控制,阐明了深层碰撞动力学与地表山地塑造之间的内在联系。此外,我们的研究结果表明,基岩性质的统一、定量表征对于理解分布在山谷系统内的侵蚀过程和危害的相互作用和变异性至关重要。

The control of collisional tectonics over valley morphology: the case of the largest glacier in the European Alps
Understanding how bedrock properties influence the valley‐forming processes of Alpine landscapes is an outstanding challenge. A multi‐methodological approach was used to uniformly quantify fault frequency, orientation, and rock hardness of crystalline basement rocks to evaluate their impact on the erosional processes that shaped the valley of the Aletsch Glacier, Switzerland. We show how variations in fault frequency and orientations, imposed by the inherited collisional framework of the area, controls the local erodibility of the valley, affecting both hillslopes and channel erosion processes. Our results highlight how tectonic preconditioning exerts a first‐order control on the efficiency of erosion in the mountain chain, elucidating an integral link between deep‐seated collisional dynamics and surface‐based mountain shaping. Moreover, our results express the importance of a uniform, quantitative characterization of bedrock properties to comprehend the interaction and variability of erosional processes and hazards distributed within the valley systems.
