Core photographs — B2–C interburden
The B2–C interburden is dominated by very fine sandstone and siltstone. Its heterolithic character is the principal core observation; environmental assignment requires bed-boundary relationships, sedimentary structures and lateral persistence rather than a log motif alone.

Geological interpretation and evidential boundary
The B2–C interburden is dominated by very fine sandstone and siltstone. Its heterolithic character is the principal core observation; environmental assignment requires bed-boundary relationships, sedimentary structures and lateral persistence rather than a log motif alone. In the thesis, the core is treated as a vertical succession: contacts, grain-size changes, structures and missing recovery are retained rather than averaged into one lithology name. Correlation gains weight when adjacent boreholes reproduce that ordered facies transition together with the log marker; an isolated look-alike bed is not a chronostratigraphic datum. The matching internship panel documents provenance continuity and is not counted as a second sample.
