RTB 11 Stratigraphic Panel — Sheet 26
Sheet 26 is tranche 2 of the 4-sheet RTB 11 profile, bounded by Sheets 25 and 27; continuity at both joins is part of the evidence. The thesis correlation places Seam A1 at about 29–37 m and Seam B2 at about 104–109 m in RTB 11, providing two separated anchors for testing track alignment and intervening stratigraphy.

Geological interpretation and evidential boundary
Sheet 26 is tranche 2 of the 4-sheet RTB 11 profile, bounded by Sheets 25 and 27; continuity at both joins is part of the evidence. The thesis correlation places Seam A1 at about 29–37 m and Seam B2 at about 104–109 m in RTB 11, providing two separated anchors for testing track alignment and intervening stratigraphy. Coal markers are transferred only where the low-gamma interval, density response and core-defined roof and floor remain aligned; short excursions may represent a parting, vertical averaging or a depth mismatch. Taken with its neighbouring tranches, RTB 11 Sheet 26 is auditable correlation control—not independent evidence for depositional environment, coal quality or lateral persistence.
