a Eiberg TOC results plotted in a modified Van Krevelen diagram (HI vs. OI). b–c Tiefengraben and Schlossgraben TOC data plotted in a HI vs. Tmax diagram (Espitalié et al. 1985a, b, c), respectively. The three sections display a continental/oxidated OM contribution of Type III except for three samples from the Eiberg section (from the base of the thick calcareous interval), characterized by preserved marine OM of Type II
