lithology of the Cap d’Ailly composite section, compared to published δ13Corg (Magioncalda, 2004), dinoflagellate (Iakovleva, 2016), nannoplankton (Aubry, 1983) and charophyte (Aubry et al., 2005) data along with K-Ar absolute ages on authigenic glauconite (this work). CIE (carbon isotope excursions) 1 to 3 and P1 and P2 correspond to negative δ13C excursions and peaks unraveled by Magioncalda, (2004). Green rectangle: interval spanned by the Phare d’Ailly core studied here. L1 and L2: lignite complex 1 and 2.
