Abstract
La campagne Escarmed 3 succède à toute une série de prélèvements effectués par des navires français et italiens. Les paléoenvironnements mésozoïques et cénozoïques de quelques marges du bassin Ionien profond (Méditerranée orientale) et plus particulièrement ceux de l'escarpement de Malte ont pu être reconstitués partiellement grâce à une étude biostratigraphique. Aux faciès de plate-forme du Trias et Lias inférieur-moyen succèdent, comme en Sicile, des séries pélagiques au Jurassique moyen et supérieur. Au Crétacé inférieur, lacunes ou érosions caractérisent la série de l'escarpement de Malte par opposition aux séries de plate-forme des monts de Médine. Dès l'Albien jusqu'au Miocène, la sédimentation est à dominance pélagique avec présence locale de dépôts circalittoraux et brèches à éléments de plate-forme (Maestrichtien, Eocène, Oligocène) ou phénomènes d'érosion, voire hiatus (Cénomanien-Turonien). Les faciès franchement pélagiques du Pliocène succèdent à la phase d'érosion du Miocène supérieur. Enfin, on notera un magmatisme important accompagnant des phénomènes de distension dès le Jurassique supérieur.
The Escarmed 3 coring and dredging campaign in the Ionian Sea comes after a series of similar surveys by French and Italian vessels. They made it possible to partially reconstruct the Mesozoic and Cenozoic paleoenvironments of several margins of the deep Ionian basin (Eastern Mediterranean), especially those of the Malta escarpment, on the basis of biostratigraphic analysis. Whereas a shallow-water environment prevailed during the Triassic and the Lower to Middle Lias period, pelagic facies are observed in the Middle-Upper Jurassic series of this area, just as has been found in Sicily. During the Lower Cretaceous, gaps or erosions characterize the Malta Escarpment, whereas the Medina seamounts are subject to continuous shelf sedimentation. From the Albian up to the Miocene, sedimentation is mainly pelagic, with local circalittoral deposits, breccias (containing Maestrichtian, Eocene and Oligocene shelf elements), erosional features, even gaps (Cenonanian-Turonian). After the Late Miocene erosional event, true pelagic facies develop in all areas. Sizeable volcanic activity, beginning in the late Jurassic, is associated with extensional tectonic movements.
