Gamma-ray motifs and density-log convention
This page establishes the log-reading grammar used in the paper. Low gamma response and a boxcar or cylindrical motif are associated with coal, whereas serrated or irregular traces characterize mineralogically mixed interburden; the source also uses density counts per second, whose direction must not be confused with calibrated bulk-density units.

Geological interpretation and evidential boundary
This page establishes the log-reading grammar used in the paper. Low gamma response and a boxcar or cylindrical motif are associated with coal, whereas serrated or irregular traces characterize mineralogically mixed interburden; the source also uses density counts per second, whose direction must not be confused with calibrated bulk-density units. Motif names are descriptive geometries. They become geological only when depth-matched to core, and they cannot uniquely identify a depositional environment because bed thickness, borehole conditions, tool response and contrasting lithologies can produce similar shapes.
