“…Ice advance is also demonstrated at Warren Hill (Three Hills), High Lodge, Lakenheath, Feltwell and Shouldham Thorpe [40,132,150,[151][152][153] (figure 14). Here Feltwell Formation meltwater deposits, comparable to those at Tottenhill, accumulated [54]. The Fenland Basin was entirely filled by a glacier during the Late Wolstonian Substage.…”

“…Evidence of glaciation to the southeast in the Fenland Basin during the Late Wolstonian Substage is indicated by ice-contact, glacio-marginal delta fan deposits in proglacial lakes impounded by ice [150]. The deposits form part of a series of local glaciofluvial delta fans first identified at Tottenhill, Norfolk, that extended into proglacial lakes [54,55,149]. Ice advance is also demonstrated at Warren Hill (Three Hills), High Lodge, Lakenheath, Feltwell and Shouldham Thorpe [40,132,150,[151][152][153] (figure 14).…”

“…This ice lobe formed the eastern sector of the northeast Oadby ice in the English West Midlands and advanced down the east coast of England, entering the Fenland Basin and impounded itself against the higher ground of the Fenland margins [40,133,154]. It re-organized the rivers Nene, Ouse and Cam, and dammed several proglacial lakes within the Fenland Basin, and the Nene and Welland catchments [54,132,133,155,156]. Six luminescence ages from Shouldham Thorpe and Watlington in Norfolk and Maidscross Hill in Suffolk between 212 ± 9 and 169 ± 6 ka have been reported by Gibbard et al [156] as representing ice-marginal delta and alluvial fan deposits within the Fenland Basin as ice advance during the Late Wolstonian Substage.…”

Timing and dynamics of Late Wolstonian Substage ‘Moreton Stadial’ (MIS 6) glaciation in the English West Midlands, UK

Glaciation during the late Middle Pleistocene is widely recognized across continental northwest Europe, but its extent and palaeoenvironmental significance in the British Isles are disputed. Although glaciogenic sediments at Wolston, Warwickshire, in the English West Midlands, have been used to define the stratotype of the Wolstonian Stage, their age has been variably assigned between marine isotope stages (MIS) 12 and 6. Here we present sedimentological and stratigraphical observations from five sites across the English West Midlands whose chronology is constrained by new luminescence ages from glaciofluvial sediments, supplemented by cosmogenic 36 Cl exposure dating of erratic boulders. The ages suggest that between 199 ± 5 and 147 ± 2.5 ka the British Ice Sheet advanced into the English West Midlands as far south as Moreton-in-Marsh, Gloucestershire. This advance is assigned to the Moreton Stadial of the Late Wolstonian Substage. Dating of the glaciation to this substage allows correlation of the Moreton Stadial glacial deposits in the English West Midlands with those of the Drenthe Stadial during the Late Saalian Substage across continental northwest Europe.

Glacial fluctuations leave distinct imprints on the landscapes of mountain environments, such as moraines and outwash terraces, that allow the reconstruction of past environmental changes. Unraveling the environmental history of the valleys of the Subtropical Andes of Argentina poses challenges due to the complex interplay of various surficial processes driven by both climatic and tectonic forces, which affects the preservation of glacial deposits. Consequently, there are few studies on past glaciations in this region compared to the rest of the Andes. This study focused on the lower section of the Blanco River Basin and the piedmont of the Frontal Cordillera in the south of San Juan Province, Argentina. A comprehensive geomorphological map of glacial landforms was created, along with sedimentological studies of outwash terraces. Additionally, numerical ages were obtained for both landforms using terrestrial cosmogenic nuclides for moraine boulders and luminescence dating for sandy layers in the outwash terraces. Our findings reveal at least two glacial advances since the Last Glacial Maximum (LGM), each associated with distinct outwash levels. The Río Blanco Advance occurred during the LGM, and the Laguna Advance is assigned to the late stages of the LGM, both with their corresponding outwash terraces. Additionally, the Amarillo Advance is believed to have occurred during the Holocene period and an older Marine Istope Stage 5 d named Guanaquito Advance. The provided data add valuable numerical information about glacial fluctuations since the LGM and also reveal the impact of glacial downwasting on piedmont landforms.
