“…The distinctive suite of lithologies and palynomorphs within Facies A of the Skipsea Till at Re-examination of Middle Pleistocene tills in County Durham (Davies et al, 2010) and north Norfolk (Lee et al, 2002) reveals a broad suite of diagnostically British clast lithologies and palynomorphs, rejecting earlier predictions of a Scandinavian provenance in these units (Trechmann, 1915(Trechmann, , 1931Boswell, 1916;Bridge & Hopson, 1985;.

The ice flow path and dynamic behaviour of the British-Irish Ice Sheet has been subject to renewed interest and controversy in recent years. Early studies in eastern England argued for interaction with Fennoscandian ice onshore in Britain, instigating re-examination of the sedimentology and provenance of many Pleistocene till successions. These studies instead supported an exclusively British provenance, and are used to predict southward advance of a broadly coast parallel North Sea Lobe. Quantitative lithological and palynological analysis of the Pleistocene till succession in Holderness, East Yorkshire, however, remains to be carried out. We examined the lithologically diverse Skipsea Till in order to reconstruct ice flow pathways to the Holderness coast during the Pleistocene, thereby constraining which areas of substrate were subglacially eroded and entrained prior to deposition. The till yields a diverse range of soft, low-durability and uniquely British allochthonous material, including Permian Magnesian Limestone, Carboniferous limestone and coal, and Carboniferous pollen and spore assemblages that would be unlikely to survive polyphase reworking. Ice extended southwards through southern Scotland, incorporating material in north ease England, northern Yorkshire and the western margin of the North Sea Basin (NSB), supporting a recurrent ice flow

“…Coalescence of the FIS and the BIIS in the North Sea Basin has been suggested during the MIS 12, MIS 6 and the MIS 5d to 2 glaciations (Boswell, 1916;Perrin et al, 1979;Catt and Digby, 1988;Bowen, 1999; extensive, with ice sheets extending southwards and eastwards from Norway (Ehlers et al, 1984;Baumann et al, 1995;Eissmann, 2002;Houmark-Nielsen and Gibbard, 2004). A large ice sheet is supported by the presence of tunnel valleys offshore (Huuse and Lykke-Andersen, 2000;Praeg, 2003).…”

At various times during the Quaternary, north-eastern England was a zone of confluence between dynamic ice lobes sourced from the Pennines, northern Scotland, the Cheviots, and Scandinavia. The region thus has some of the most complex exposures of Middle to Late Pleistocene sediments in Britain, with both interglacial and glacial sediments deposited in terrestrial and marine settings. We investigated sedimentary sequences exposed on the coastline of County Durham at Warren House Gill, and present a new model of British and Fennoscandian Ice Sheet interaction in the North Sea Basin during the Middle Pleistocene.The stratigraphy at Warren House Gill consists of a lower diamicton and upper estuarine sediments, both part of the Warren House Formation. They are separated from the overlying Weichselian Blackhall and Horden tills by a substantial unconformity. The lower diamicton of the Warren House Formation is re-interpreted here as an MIS 8 to 12 glaciomarine deposit containing ice-rafted lithics from north-eastern Scotland and the northeast North Sea, and is renamed the 'Ash Gill Member'. It is dated by lithological comparison to the Easington Raised Beach, Middle Pleistocene Amino Acid Racemisation values, and indirectly by optically stimulated luminescence. The overlying shallow subaqueous sediments were deposited in an estuarine environment by suspension settling and bottom current activity. They are named the 'Whitesides Member', and form the uppermost member of the Warren House Formation. During glaciation, ice-rafted material was deposited in a marine embayment. There is no evidence of a grounded, onshore Scandinavian ice sheet in County Durham during MIS 6, which has long been held as the accepted stratigraphy. This has major implications for the currently accepted British Quaternary Stratigraphy. Combined with recent work on the Middle Pleistocene North Sea Drift from Norfolk, which is now suggested to have been deposited by a Scottish ice sheet, the presence of a Scandinavian ice sheet in eastern England Quaternary Science Reviews 44 (2012), 180-212 2 at any time during the Quaternary is becoming increasingly doubtful.

“…316 R. S. SEALE Among the diagnostic minerals indicating glacial drift is garnet, as has been stressed by earlier writers such as Rastall (1913), Boswell (1916), and Solomon (1932). In the drift it occurs as relatively large orange or transparent pink grains, the former often with numerous inclusions and the latter often etched.…”
