Visual categorization of the bore-cores BDR-D1 and BDR-D2 (5.5–15.5 m WD). Upper left: identified categories on cores from BDR-D1 (top) and BDR-D2 (bottom). The correlation plot (upper right) highlights the agreement between the two cores, and thus the alignment of the bedding planes. An image of the segment from 5 to 8 m of the two cores next to each other (bottom) shows the aligned bedding features. Marked by a red rectangle is a fossil-rich whitish layer, occurring in both cores at a depth of 7.25 m. For further images of bore-core BDR-D2, please refer to the Appendix.
