RTB 09 Stratigraphic Panel — Sheet 21
Sheet 21 is tranche 2 of the 5-sheet RTB 09 profile, bounded by Sheets 20 and 22; continuity at both joins is part of the evidence. Across the complete RTB 09 profile, Seam D is source-correlated at approximately 142–147 m; that interval is an anchor for checking the order and scale carried across these sheets.

Geological interpretation and evidential boundary
Sheet 21 is tranche 2 of the 5-sheet RTB 09 profile, bounded by Sheets 20 and 22; continuity at both joins is part of the evidence. Across the complete RTB 09 profile, Seam D is source-correlated at approximately 142–147 m; that interval is an anchor for checking the order and scale carried across these sheets. 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 09 Sheet 21 is auditable correlation control—not independent evidence for depositional environment, coal quality or lateral persistence.
