Popis: The continental series of Uppermost Maastrichtian/‘Lower Paleocene’ includes 6 palaeosurfaces induced by the erosion of alluvial marls and the karstification of lacustrine/ palustrine limestones within a subtropical climate characterized by a moderate pluviometry. An estimation of the whole gap gives a relatively high extension which must be taken into consideration in the stratigraphic studies and the search for the iridium anomaly at the K/T boundary. The evidenced discontinuities are helpful for correlations between continental and marine domains as they may refer to low stand episodes.
