Electrofacies — B1–B2 interburden
In the thesis correlation, the B1–B2 is bounded by coal markers already identified in core. The irregular gamma motif is consistent with the observed alternation—between b1 and b2, the source describes pale grey claystone and siltstone with fine heterolithic layering—but the curve is an averaged petrophysical response rather than a facies name.

Geological interpretation and evidential boundary
In the thesis correlation, the B1–B2 is bounded by coal markers already identified in core. The irregular gamma motif is consistent with the observed alternation—between b1 and b2, the source describes pale grey claystone and siltstone with fine heterolithic layering—but the curve is an averaged petrophysical response rather than a facies name. The interpretation is retained only where the depth match, density track, recovery record and neighbouring wells exclude a simpler logging or sampling explanation. The corresponding internship figure is the same record in an earlier report context, not independent confirmation.
