%X La dorsale des Pouilles s¨¦pare, suivant une direction NW-SE, le Bassin Adriatique du Bassin Ionien. Un grand nombre de relev¨¦s de sismique r¨¦flexion a permis d'¨¦tudier les caract¨¦ristiques de sa couverture s¨¦dimentaire r¨¦cente et les directions des accidents distensifs (essentiellement NW-SE, NS et EW) qui la d¨¦coupent. Cette ¨¦tude permet de distinguer deux grands secteurs ayant une ¨¦volution tectonique diff¨¦rente ¨¤ partir du Mioc¨¨ne sup¨¦rieur. Sa marge Adriatique est s¨¦diment¨¦e et faiblement tectonis¨¦e. Sa marge Ionienne ne poss¨¨de qu'une mince couverture r¨¦cente et est d¨¦coup¨¦e par un dense r¨¦seau d'accidents distensifs encore actifs pour la plupart. The submerged Apulian swell constitutes a wide, dissymmetric NW-SE trending topographic high extending from Apulia to Kephalinia in the northern lonian Sea. It separates the relatively shallow southern Adriatic basic from te deeper lonian Sea. In recent years a systematic survey (including dredging and seismic profiling) has been made by IGM Bologna across the whole area to study its sedimentary cover and shallow structure and to, determine its general recent evolution. The different maps of the swell show two margins. Toward the NE (Adriatic margin) the Apulian slope is gentle, wide and sedimented. Toward the SW (lonian margin) the slope comprises a series of steep scarps facing the deep lonian basin and the Taranto valley. This asymmetry reflects a comparable opposition between the two margins at the Ievel of both the sedimentary cover and the structural framework.
