This paper presents the results of a detailed study of a sequence of Late Devensian (Weichselian) sands, gravels and diamictons exposed within a recessional moraine near Loch Killin, near Fort Augustus, Monadhliath Mountains, NE Scotland. Macroscale sedimentological and structural field observations are combined with micromorphological and micro-structural analysis to investigate the ice-marginal processes which led to the construction of this landform. Microstructures present within the stratified diamictons mantling the glacitectonised core of the moraine reveal a complex history of microfabric development resulting from ductile shearing during the emplacement of these ice-marginal mass flow deposits. Shearing occurred throughout the entire mass flow with flowage occurring towards the WNW. The laminated sediments which infill a number of steeply inclined hydrofractures which cut the moraine are interpreted as having accommodated several phases of fluid flow, with a palaeoflow direction towards the WNW. A detailed model of ice-marginal landform development has been established involving glacitectonism as a result of ice-push during a readvance of the glacier, followed by mass flow of sediments released as a result of melting of the snout during a period of still stand, followed by hydrofracturing accompanying the escape of pressurised meltwater from beneath the ice, probably during the initial stages of glacier retreat.

本文介绍了对苏格兰东北部莫纳迪利亚特山脉奥古斯都堡附近的奇林湖附近的凹陷冰m中暴露的一系列晚期德文斯（Weichselian）砂，砾石和双子叠层的详细研究结果。宏观沉积学和结构野外观测与微观形态和微观结构分析相结合，以研究导致该地貌建设的冰缘过程。存在于层状冰amic的层状双甲酰胺中的微结构，揭示了冰缘质流沉积物放置期间的韧性剪切作用，从而揭示了微织物发展的复杂历史。剪切发生在整个质量流中，并且流向WNW。填充了许多切割冰inclined的陡峭倾斜裂缝的层状沉积物被解释为已容纳了流体的多个相，其古流向WNW。建立了一个详细的冰缘地貌发展模型，其中包括冰川恢复期间因推冰而造成的冰川活动，随后在静止期期间由于口鼻融化而释放的沉积物的大量流动，随后伴随着加压融化水从冰下逸出的水力压裂，可能是在冰川退缩的初期。
