Figure F13. Stratigraphic logs, calcareous nannofossil datums, and total organic carbon (TOC) data, Site U1407. The interval includes the late Cenomanian through early Turonian and the Oceanic Anoxic Event 2 interval. The stratigraphic log accompanying the core scan photograph has a stylized weathering profile that denotes the relative resistance of the chalks to the more friable black shale and claystone.
