Abstract

The most widespread depositional landforms in many of the upland valleys of the British Isles which have undergone glaciation during the Last Glacial Maximum (LGM) are so-called solifluction sheets. This paper presents the first dates from these landforms in the British Isles. The AA. used optical dating on deposits exposed at Linhope Burn in the Cheviot Hills of North East England. The results suggest that the bulk of sediment deposition at this site happened over a period spanning the Younger Dryas. The AA. argue that both paraglacial and periglacial processes can account for the main periods of deposition and that the timing of sediment deposition reflects the rapidity with which landform development responded to climatic shifts
