Parting within Seam A2
The A2 parting photograph isolates a thin non-coal interval within an otherwise thick, approximately 12–15 m seam envelope. Its thickness, lithology and continuity affect clean-coal thickness, dilution and quality sampling, so it should be logged separately rather than absorbed into an average seam description.
SOURCE-LED TECHNICAL READING
Geological interpretation and evidential boundary
The A2 parting photograph isolates a thin non-coal interval within an otherwise thick, approximately 12–15 m seam envelope. Its thickness, lithology and continuity affect clean-coal thickness, dilution and quality sampling, so it should be logged separately rather than absorbed into an average seam description. Whether the parting records a short clastic influx, peat interruption or local reworking cannot be decided from one core image; lateral recurrence in other wells is the discriminating observation.
