“…In borehole BGS ID 774788 there is 6 m of diamicton at the base of the palaeo-valley, which becomes increasingly sand-rich towards the top. The diamicton is overlain by over 60 m of laminated glaciomarine clay (Parthasarathy & Blyth 1959). This is overlain in turn by raised beach deposits and Holocene-age alluvium (Parthasarathy & Blyth 1959).…”

“…One area of the UK where sufficient sub‐surfaceborehole data exist to reconstruct the geometry and cross‐cutting relationships of the network of buried palaeo‐valleys is the Midland Valley of Scotland. Here, boreholes (>100 m depth) with thick sequences of Quaternary sediments have been used to suggest the presence of buried palaeo‐valley systems beneath Alva in Clackmannan (Parthasarathy & Blyth ), under the modern River Kelvin to the northwest of Glasgow (Browne & McMillan ; Rose & Smith ; Finlayson ) and under Grangemouth (Cameron ). Additionally, several shallower ‘drift‐filled buried channels’ have been recorded in the vicinity of Irvine, Ayrshire (Monro ).…”

Buried palaeo‐valley systems have been identified widely beneath lowland parts of the UK including eastern England, central England, south Wales and the North Sea. In the Midland Valley of Scotland palaeo‐valleys have been identified yet the age and genesis of these enigmatic features remain poorly understood. This study utilizes a digital data set of over 100 000 boreholes that penetrate the full thickness of deposits in the Midland Valley of Scotland. It identified 18 buried palaeo‐valleys, which range from 4 to 36 km in length and 24 to 162 m in depth. Geometric analysis has revealed four distinct valley morphologies, which were formed by different subglacial and subaerial processes. Some palaeo‐valleys cross‐cut each other with the deepest features aligning east–west. These east–west features align with the reconstructed ice‐flow direction under maximum conditions of the Main Late Devensian glaciation. The shallower features appear more aligned to ice‐flow direction during ice‐sheet retreat, and were therefore probably incised under more restricted ice‐sheet configurations. The bedrock lithology influences and enhances the position and depth of palaeo‐valleys in this lowland glacial terrain. Faults have juxtaposed Palaeozoic sedimentary and igneous rocks and the deepest palaeo‐valleys occur immediately down‐ice of knick‐points in the more resistant igneous bedrock. The features are regularly reused and the fills are dominated by glacial fluvial and glacial marine deposits. This suggests that the majority of infilling of the features happened during deglaciation and may be unrelated to the processes that cut them.

Lithostratigraphical studies coupled with the development of new dating methods has led to significant progress in understanding the Late Pleistocene terrestrial record in Scotland. Systematic analysis and re-evaluation of key localities have provided new insights into the complexity of the event stratigraphy in some regions and the timing of Late Pleistocene environmental changes, but few additional critical sites have been described in the past 25 years. The terrestrial stratigraphic record remains important for understanding the timing, sequence and patterns of glaciation and deglaciation during the last glacial/interglacial cycle. Former interpretations of ice-free areas in peripheral areas during the Last Glacial Maximum (LGM) are inconsistent with current stratigraphic and dating evidence. Significant challenges remain to determine events and patterns of glaciation during the Early and Middle Devensian, particularly in the context of offshore evidence and ice sheet modelling that indicate significant build-up of ice throughout much of the period. The terrestrial evidence broadly supports recent reconstructions of a highly dynamic and climate-sensitive British-Irish Ice Sheet (BIIS), which apparently reached its greatest thickness in Scotland between 30 and 27 ka, before the global LGM. A thick (relative to topography) integrated ice sheet reaching the shelf edge with a simple ice-divide structure was replaced after the LGM by a much thinner one comprising multiple dispersion centres and a more complex flow structure.
