Figure 6.
A detailed core log profile of magnetic susceptibility (MS) (A) from the Baltic Basin displaying a succession from the Ordovician–Silurian rocks of the drill core D. The MS profile is compared with the bioturbation index (BI) log (B), total organic carbon (TOC) content (C), oxygen index (OI) log (D), and percent amounts of chlorite (E). In gray and pink, characteristic peaks were marked to clarify differences in trend for each parameter. K = bulk magnetic susceptibility.
