Figure F17. Core images of stratigraphic inversions from the upper Danian to Campanian, Site U1407. A relatively complete upper Paleocene to Danian sequence (see “Biostratigraphy”) is truncated by a series of unconformities and stratigraphic inversions spanning the upper Danian to lower Campanian (nannofossil Zone NP4 to Subzone UC14d/UC15a). The Maastrichtian unconformity (nannofossil Zones UC20–UC16) is only identified in Hole U1407C and may be attributed to either the biostratigraphic resolution over that interval or local variation in postdepositional processes.
