RTB 09 Stratigraphic Panel — Sheet 23
Sheet 23 is tranche 4 of the 5-sheet RTB 09 profile, bounded by Sheets 22 and 24; 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 23 is tranche 4 of the 5-sheet RTB 09 profile, bounded by Sheets 22 and 24; 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. Any scale reset, missing depth or track displacement at a sheet boundary can imitate a seam split or thickness change, so the page join is a geological quality-control step rather than a graphic detail. Taken with its neighbouring tranches, RTB 09 Sheet 23 is auditable correlation control—not independent evidence for depositional environment, coal quality or lateral persistence.
