Les séquences plio-pléistocènes littorales et estuariennes de Normandie [Littoral and estuarine plio-pleistocene sequences in Normandy (France)]

Abstract: Plusieurs longues séquences du Pleistocene moyen et supérieur ont été définies en Normandie, notamment dans la partie aval de la vallée de la Seine (Tourville et Tancarville) et dans le Cotentin (Port-Racine, Écalgrain). On a pu ainsi caractériser les formations marines ou fluvio- marines des stades isotopiques 5 et 7 grâce aux datations, à la faune et à la stratigraphie des dépôts continentaux périglaciaires de couverture. Des sites plus anciens, bien datés, concernent d'une part le Reuvérien de Rouen (La Lon… Show more

“…The first source is common in those Chalk caves studied in Normandy, for example the Petites Dales, Villequier II and Orival-Foulon caves (Laignel et al, 2004;Rodet et al, 2006;Chédeville et al, 2015). Nevertheless, the main source of the sediment in these caves is the aeolian sediment that was deposited on the Chalk plateau during the last glacial period (Lautridou et al, 1999). Loess-derived-sediment was not recognised within the Caumont cave system, at least, not in allostratigraphical units 1-3.…”

“…During this time, the River Seine developed large free and semi-entrenched (ingrown) meanders (Fig. 1c) (Genuite et al, 2021) and fluvial terraces (Lautridou et al, 1999;Antoine et al, 2000Antoine et al, , 2007. Coevally, the karstification has created branchwork and maze caves (Rodet, 2013), typically associated with inception horizons on low permeability beds (hardgrounds, marls and sheet flints) within the Chalk (Ballesteros et al, 2020;Farrant et al, 2023).…”

“…Jalonné de gros galets marins, ce niveau a été reconnu lors des fouilles archéologiques entreprises sur le site de la Roche Gélétan ( fig. 3) (Michel et al, 1994 ;Coutard et al, 2002). Entre 20 et 25 m, Elhaï (1963) signale des galets épars sur une plate-forme dégradée, qui résultent du démantèlement d'une très haute plage bien conservée en Val de Saire (Coutard, 2003).…”

“…The north of the island is dominated by high (up to 130m) cliffs of plutonic and volcanic rocks with a conglomerate forming the lower plateau in the northeast. In the south and southeast lies a c2km wide coastal plain, overlooked by the ubiquitous fossil cliff line, trimmed in Middle and Upper Pleistocene times, but with its origins at least in the early Tertiary (Lautridou 1989, Renouf 1993.…”
