A large-scale, cross-stratified, gravel-dominated facies (A) dips predominantly offshore and is interpreted as a beach-face deposit. This facies passes seawards into a {\textquoteright}transitional{\textquoteright} zone characterized by a horizontally stratified sand facies (B). This is incised into, and replaced seawards, by a third facies (C) deposited in channel-forms. Nearshore these channels are gravel-filled; further offshore they are regularly spaced, up to 2 m deep, their bases commonly being rimmed by gravel which fines upwards into sand. Several such fining-upward pulses are present in the infill of some of the larger channel-forms. It is suggested that these channels were cut and infilled by sporadic high-energy seaward-directed rip-currents.}, author = {Mathers, S.J. and Zalasiewicz, J.A.} } @article {1161, title = {Stratigraphy and Palaeoenvironments of the Red Crag and Norwich Crag Formations Between Aldeburgh and Sizewell, Suffolk, England}, journal = {Philosophical Transactions of the Royal Society B}, volume = {322}, year = {1988}, chapter = {221}, author = {Zalasiewicz, J.A. and Mathers, S.J. and Hughes, M.J. and Gibbard, P.L. and Peglar, S.M. and Harland, R. and Nicholson, R.A. and Boulton, G.S. and Cambridge, P. and Wealthall, G.P.} } @article {1160, title = {Lithostratigraphy of the Red and Norwich Crags of the Aldeburgh-Orford Area, south-east SUffolk}, journal = {Geological Magazine}, volume = {122}, year = {1985}, chapter = {287}, abstract = {Recent investigations indicate that three distinct lithostratigraphical units can be recognised in the Red and Norwich Crag deposits of the area around Aldeburgh and Orford, Suffolk. These effectively represent a refinement of a stratigraphy originally suggested by Prestwich in 1871. A lowermost coarse-grained shelly sand, the Red Crag Formation, rests on an eroded London Clay surface and is banked against the Pliocene Coralline Crag. The Red Crag Formation passes upwards into a fine-grained generally unfossiliferous well-sorted sand, the Chillesford Sand Member, which overlaps the Red Crag Formation to rest directly on the Coralline Crag. The Chillesford Clay Member is regarded as the lateral equivalent of the upper Chillesford Sand Member, the two members together comprising the Norwich Crag Formation in this area. Sections that have been zoned palaeontologically may be integrated into this lithostratigraphical framework. These indicate that the Red Crag Formation correlates with the Pre-Ludhamian Stage, and the Chillesford Sand Member and the Chillesford Clay Member correlate with the Bramertonian Stage. Type sections are established for the three units described.}, author = {Zalasiewicz, J.A. and Mathers, S.J.} } @article {314, title = {The lithostratigraphy of the Coralline Crag (Pliocene) of Suffolk}, journal = {Proceedings of the Geologists{\textquoteright} Association}, volume = {104}, year = {1993}, chapter = {59}, abstract = {A series of 7 boreholes (3 rotary and 4 shell and auger) were drilled by the British Geological Survey through the main outcrop of the Pliocene Coralline Crag Formation between Gedgrave and Aldeburgh in Suffolk between 1982 and 1985. The boreholes proved three members distinguished on the basis of grain size, sorting, carbonate content and fauna. The oldest, the Ramsholt Member, rests unconformably on the Palaeocene-Eocene London Clay Formation. It comprises a basal phosphorite-rich gravel with shelly mud-rich sands above. The Sudbourne Member unconformably overlies the Ramsholt Member and consists of cross-stratified, well-sorted carbonate sands, laid down as a tidal sand ridge. A third member, the Aldeburgh Member is found only in the northern part of the outcrop where it overlies the Ramshot Member. It consists of mud-poor, moderately sorted carbonate sand, and is probably the offshore (deeper water) equivalent of the Sudbourne Member.}, author = {Balson, Peter S. and Mathers, S.J. and Zalasiewicz} }
