Core photographs — Seam D
The source places Seam D at about 142–147 m in RTB 09 and 181–185 m in RTS 01; the correlated coal interval is approximately 4 m thick and is described as banded coal, locally with a clay band or parting. In the thesis evidence chain, the photograph records recovered material and superposition but does not directly demonstrate between-well continuity.
SOURCE-LED TECHNICAL READING
Geological interpretation and evidential boundary
The source places Seam D at about 142–147 m in RTB 09 and 181–185 m in RTS 01; the correlated coal interval is approximately 4 m thick and is described as banded coal, locally with a clay band or parting. In the thesis evidence chain, the photograph records recovered material and superposition but does not directly demonstrate between-well continuity. Core-scale banding and partings may be described visually; coal rank, peat affinity and quality cannot be inferred without the laboratory dataset. Correlation through two boreholes is strongest where the photographed contacts coincide with the same gamma and density markers in depth; recovery loss, fragmentation and depth mismatch must be ruled out before a thickness difference is treated as geological. Where this panel also occurs in the internship report, the duplication is treated as traceable reuse rather than replication.
