Evidence from the Trent terrace archive, Lincolnshire, UK, for lowland glaciation of Britain during the Middle and Late Pleistocene

The late Middle Pleistocene fluvial terrace sequence of the lower Trent system, Lincolnshire (eastern England), provides an excellent record of environmental change, including evidence for the last two interglacial episodes. It also provides important stratigraphical evidence for the timing and extent of three separate glaciations. Two of these, the Anglian and Devensian, are well-established correlatives of Marine Isotope Stages (MIS) 12 and 2 respectively; the third is a hitherto un-named post-Anglian-pre-Devensian glaciation in eastern England that has been the subject of much previous speculation, but can now be attributed with some confidence to MIS 8. Crucially, the recognition of MIS 7 interglacial deposits within the Balderton-Southrey terrace of the proto-Trent indicates that the underlying Wragby Till, which is ascribed to this additional glaciation, was emplaced no later than MIS 8. The oldest terrace preserved within the lower Trent staircase, the Eagle Moor-Martin Terrace, is considered to be a complex glacial outwash terrace related to the Wragby Till glaciation. It is suggested that deposits representing MIS 11-9, which are conspicuously absent throughout the Trent system, were removed by this glaciation. This is a departure from previous interpretations, which have suggested MIS 10 or MIS 6 as the most likely stages in which an extensive post-Anglian-pre-Devensian lowland glaciation might have occurred in Britain. However, the widespread preservation of undisrupted post-MIS 8 fluvial sequences throughout the Trent valley and in neighbouring systems, within which MIS 7 interglacial deposits have now been recognized at a number of localities, indicates that ice sheets are unlikely to have advanced further into this catchment during MIS 6 than during the Devensian (MIS 2). Recognition of a British glaciation during MIS 8 corresponds with widespread evidence in Europe, which suggests that glacial deposits classified as ‘Saalian’ represent both MIS 8 and MIS 6; in many areas, distinguishing these remains controversial, as confident correlation with either stage is often only possible where glacial sediments interdigitate with well-constrained fluvial records.     

Extrinsic and intrinsic forcing of fluvial development: understanding natural and anthropogenic influences

This paper introduces a special issue arising from the biennial meeting of the Fluvial Archives Group (FLAG) that took place in September 2008 in Budapest, Hungary. Combining a two-day conference and three-day field excursion, this meeting provided an excellent opportunity for presentation and discussion of recent advances in research on fluvial evolution from the Plio-Pleistocene to the historical period. This editorial seeks to place these advances within the contexts both of long-term geomorphological research and the achievements of FLAG. It thus highlights progress towards a better understanding of fluvial responses to internal and external (including anthropogenic) forcing. It also points out some of the main obstacles, which can be targeted as goals for further research. Typically these relate to observed discrepancies in fluvial system responses, such as in patterns of lateral erosion and the timing of terrace incision, despite apparently similar fluvial parameters. Possible explanations for these discrepancies are mentioned, and the potential of new methods (especially in geochronology and modelling) to clarify such discrepancies is underlined. Finally the editorial provides brief reviews of the ten papers in this special issue (many of them developed from presentations in Budapest), which cover various areas in Europe (Hungary, England, Germany, Portugal, Russia), Asia (India) and South America (Bolivian Andes), placing them, in turn, within the context of this wider review of fluvial research.
