“…The tills of the east Yorkshire coast are divided into three units, the Basement, Skipsea and Withernsea Tills. The diamictons exposed in Bridlington Bay are regarded as part of the Skipsea Till, except where Basement Till is occasionally exposed by beach erosion (Bisat, 1939(Bisat, , 1940 Catt and Madgett, 1981). In Filey Bay, Edwards (1981) identifies two tills and, despite the lithological and structural complexities created by glaciotectonics, correlates them with the Skipsea and Withernsea Tills although the latter till does not crop out in Holderness north of Hornsea (Catt, 1991).…”

The stratigraphy and sedimentology of the glacial deposits exposed along the coast of east Yorkshire are reviewed. Critical sections at Filey Brigg, Barmston and Skipsea are examined to reassess the stratigraphy of Devensian Dimlington Stadial glacial deposits in the light of recent developments in glacial sedimentology. Sedimentary and glaciotectonic structures studied in the field and by using scanning electron microscopy are emphasised. Two hypotheses are considered for the genesis of the interbedded diamictons and stratified sediments. The first involves the deposition of lodgement till and/or deformation till followed by meltout till, which was overridden to produce more deformation till, reflecting periods of ice stagnation punctuated by glacier thickening. The second hypothesis, which is favoured on the basis of field evidence and micromorphology, involves the vertical accretion of a deforming till layer associated with cavity/ channel or tunnel valley fills, beneath active ice. At Barmston the upper part of the diamicton contains elongate pendant structures containing gravels, indicating that the diamicton was saturated and able to flow. The diamictons, therefore, represent a complex sequence of tills deposited and deformed by active ice during the Dimlington Stadial. Previously published stratigraphical schemes involving classifications of multiple tills in east Yorkshire should be simplified and it is more appropriate to assign these to a single formation, the Skipsea Till Formation. Rhythmic glaciolacustrine and proglacial glaciofluvial sediments overlie the tills at Barmston and Skipsea. These were deposited in sag basins during deglaciation as the tills settled and deformed under thickening sediment and as buried ice melted out. Extensive sands and gravels cap the succession and were deposited on a sandur during the later stages of deglaciation. Journal of QLjatprnary ~~~p~~~

“…Pleistocene till provenance in east Yorkshire: reconstructing ice flow of the British North Sea Lobe. Various studies have debated the provenance of the Skipsea Till, with some authors advocating west-east ice dispersal from the Lake District (Bisat, 1939;Foster, 1987), whilst others favour erratic transport from northern Britain (Catt & Penny, 1966;Madgett & Catt, 1978;Catt, 2007). Whilst recent re-examination of deposits considered correlative in north…”

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

“…The Hessle Till is correlated by most authors with the Hunstanton Till, which is the sole representative of the Weichsel in Norfolk. The Basement Till is visible at only a few localities on the Yorkshire coast, and contains partially digested masses of marine clay (the Sub-Basement of Bisat, 1940) and sand (the Bridlington Crag of Lamplugh, 1878Lamplugh, , 1881Lamplugh, , 1884, which were incorporated from the floor of the North Sea by the ice that deposited the Basement.…”

Macrofabric (stone orientation) and microfabric studies of the four tills exposed in the coastal areas of East Yorkshire indicate that the regional direction of ice movement during both the Saale and Weichsel Glaciations was from north-east to south-west. The Saale (Basement) Till was considerably modified by the advance of ice during the Weichsel Glaciation; in particular, the stones in the Basement were reorientated so that their long axes now lie at right angles to the direction of movement of the Weichsel ice sheet. The fabrics of the three Weichsel tills (Drab, Purple and Hessle) are alike, and it is suggested that all three were deposited from one composite ice sheet. The relationship of vertical joints in the Basement and Drab Tills to directions of ice movement is discussed; those in the Basement possibly originated as ac tension joints inherited from the parent ice, whereas some of those in the Drab are probably conjugate shear joints formed during post-depositional deformation of the till.
