RTB 09 Stratigraphic Panel — Sheet 20
Sheet 20 opens the 5-sheet RTB 09 profile and establishes the track order and scale that must remain unchanged through the following tranches. 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 20 opens the 5-sheet RTB 09 profile and establishes the track order and scale that must remain unchanged through the following tranches. 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. Read the depth column first, then test whether lithology, gamma response and density counts change at the same boundary; a visually attractive curve match that violates core order is not a valid pick. Taken with its neighbouring tranches, RTB 09 Sheet 20 is auditable correlation control—not independent evidence for depositional environment, coal quality or lateral persistence.
