Peniche section: Mass specific magnetic susceptibility (χ) and Isothermal Remanent Magnetization (IRM) parameters after unmixing using the Kruiver et al.96 software. SIRM is the saturation of isothermal remanent magnetization. Isotope composition of carbonate (δ13Ccarb) and organic carbon (δ13Corg) are from Hesselbo et al.103 and Fantasia et al.31, respectively. δ13Corg shifts identified at Yorkshire (UK, Ref.8) are shown for comparison. MC1, MC2, and MC3 correspond to the three brownish layers studied here (see also Fig. 3). D1 and D3 correspond to the discontinuities proposed by Pittet et al.44.
