Abstract
  • The Bradanic foredeep is a Pliocene and Pleistocene sedimentary basin portion of the post- Messinian Apennines foredeep (Adriatic foredeep), which migrated towards east with several deformative phases during the Pliocene and early Pleistocene. Together with the Murge peripheral bulge (Apulian Foreland) the Bradanic foredeep is the shallow crustal expression of the Apulian or Adria lithosphere subduction. The central sector of the basin is characterized by a structural narrowing with the two basin margins are far 20 km in outcrop and 1.5 km in depth. The two tectonic domains converging in correspondence of the Lavello-Banzi structural high stopped the thrusts propagation with a drastic reduction of the subsidence rates and accomodation space of the foredeep basin. This event induced the beginning of a Pleistocene regressive phase with a shallow water sea phase and the progressive basin filling either toward northeast (Adriatic sea) or toward southeast (Ionian sea) for the imposing of sedimentary supplies of Apennine origin. In agreement with this datum, the phisiography of the basin changed, developing either transversal or axial asymmetry and inducing the sedimentation of the outcropping Bradanic foredeep succession. To evaluate the possible tectonic constraints in a regional structural context as an control-element of the basin architecture of the Bradanic foredeep basin during early Pleistocene, in this work several data and models existing in literature have been re-examined also through the analysis and interpretation of deep data (wells and seismic profiles). This review contribution aims to focus on a better definition of the last evolutive phases of the Bradanic basin by means of new synthetic analysis of deep data related to surface evidences and proposing a local basin-architecture reconstruction.
