The upper Paleocene-lower Eocene stratigraphic record is currently one of the best suited for deciphering synsedimentary tectonic control on the architecture of stratigraphic sequences. In an effort to understand the drastic evolutionary, paleoceanographic and climatic events that occurred during Magnetochron C24r (from approximately 56 to approximately 53.5 Ma) a fine chronologic framework based on magnetic, paleontologic, isotopic and volcanic events has been constructed through the detailed analysis of numerous deep sea, epicontinental and terrestrial sections. This chronologic framework in turn has allowed the temporal interpretation of the sections, upon which truly temporal correlations have been established. This means that it has been possible to assess the temporal completeness of sections, particularly in the deep sea, to date precisely the surfaces associated with sequence boundaries in marginal settings, and with stratigraphic gaps in the deep sea, and to determine the corresponding hiatuses (in m.y.).
