This work defines geological stratigraphic and morphological evolution of Late Pleistocene, between Ascoli Satriano and Ordona in the province of Foggia, Southern part of Tavoliere delle Puglie. For this purpose, was performed a photogrammetric analysis with GIS integrated with morphological, geological and stratigraphic studies on the field. The work allowed to propose a new geologic framework in which have been recognized the classical quaternary stratigraphic units of the bradanic cicle as in the Lucanian part of the Plio-Pleistocene Foredeep. In particular was recognized a regressive sandy-conglomeratic unit which lies continuously on the Argille subappennine; it represents the uppermost unit of the bradanic cycle. Furthermore, at lower topographic heights were recognized eight marine sandy-conglomeratic unconformity bounded units correlated to the marine terraces of the Murge.
