AB In the Eastern Prebetic Zone of SE Spain, upper Cretaceous to lower Eocene hemipelagic sequences deposited in the ancientsouthern passive continental margin of Iberia are well exposed. The long-term stratigraphy of these sequences is punctuated by sixregional tectonic events, which induced rapid changes in palaeogeography and regional tectonics. Each event configured a newgenetic scenario for sedimentation, which lasted until the next tectonic reorganization and, in turn, controlled the deposition of anevent bounded stratigraphic unit (EBSU). The ages of these events, determined chronobiostratigraphically, are: intra-Coniacian,late Santonian, “mid” Maastrichtian, latest Maastrichtian–earliest Danian, late Thanetian and intra-Ypresian. All the events, but thefirst, are interpreted here as the result of contractional tectonic pulses, related to changes in intraplate stresses during the onset ofAfrican–European convergence. Through correlations with both adjacent shallow marine carbonates (Prebetic platform) and basinpelagites (Subbetic), along with other basins of Iberia and North Africa, the long-term evolution of the continental margin isintegrated within the geodynamic framework of the western Tethys.
