“…A lens of peat embedded in the base of the overlying red Mill of Forest Till Formation has been assigned to MIS 5a or 5c (Campbell, 1934;Auton et al, 2000), thus providing a maximum age both for the till and fs. 51 with which it is correlated.…”

We present a review of over 175 years of research into the Middle to Late Devensian (Weichselian) glaciation of north-east Scotland based crucially on both its lithostratigraphic and geomorphic records. The location of the region, and surrounding seabed, makes this unusually detailed record significant for deciphering the former interactions and dynamics of Scottish and Scandinavian ice within the North Sea Basin (NSB), which continue to be controversial. A twelve-stage event stratigraphy is proposed based on a parsimonious interpretation of stratigraphic relationships, till lithology and regional clast fabrics, striae, subglacial bedforms, ice-marginal features and published geochronometry at critical sites. The record of regional glaciation supports converging evidence that the north-eastern quadrant of the last British and Irish Ice Sheet (BIIS) reached its maximum spatial extent in the late Middle-to early Late Devensian and later re-expanded following widespread internal glacial reorganisations, marine transgression and partial retreat from the central NSB. Retreat was interrupted by several glacial readvances of limited extent. Fieldcaptured data helps identify important events that are not clearly resolved from remote sensing alone, particularly regarding growth phases of the last glaciation.

“…The presence at Sel Ayre of the exotic shrub, Bruckenthalia spiculifolia, today confined to the mountains of southeast Europe, is significant (Whittington, 1994). Bruckenthalia generally is missing from Eemian sites in northwest Europe but present at sites of Brørup and Odderade Interstadial age (Ambrosiani and Robertsson, 1992;Beaulieu and Reille, 1992), including Camp Fauld (Whittington et al, 1993), Crossbrae (Whittington et al, 1998) and Burn of Benholm (Auton et al, 2000) in Scotland. Its presence in the peat at Sel Ayre is therefore consistent with an MIS 5c age.…”

Hall, A. M., Gordon, J. E., Whittington, G., Duller, Geoff A. T., Heijns, H. (2002). Sedimentology, palaeoecology and geochronology of Marine Isotope Stage 5 deposits on the Shetland Islands, Scotland. Journal of Quarternary Science, 17 (1), 51-67.New stratigraphical, palynological and dating evidence is presented for pre-Late Devensian/Weichselian sediments at Fugla Ness and Sel Ayre, Shetland. The Fugla Ness Peat rests on till and formed during an interglacial that saw the development of maritime heaths, with scattered trees and shrubs, including Pinu5 and possibly flex. A decline into stadial conditions is marked by overlying periglacial breccia and till. The Sel Ayre Organic Sands and Gravels lie between periglacial breccias and beneath till and appear to record a changing interstadial environment in which trees were absent and the vegetation comprised largely heaths, with Bruckenthalia, and grasslands. The Fugla Ness Peat is dated to 110+40/-35 ka by uranium series disequilibrium, suggesting that it formed during the Ipswichian/Eemian Interglacial (Marine Isotope Substage 5e). Luminescence ages of ca. 98-105 ka on intercalated sands within the Sel Ayre Organic Sands and Gravels place these deposits in Marine Isotope Substage 5c (Brorup Interstadial). The two sites provide the first detailed record of Marine Isotope Stage 5 environments on Shetland. Copyright (C) 2002 John Wiley Sons, Ltd.Peer reviewe
