property · prop_bi_chronology_plateau_affected
Radiocarbon plateau or broad calibration affected
Absolute dating is widened or blurred by calibration structure and sample limitations.
Review and provenance
Specialist reviewer: not recorded. Review date: not recorded.
Dataset workflow: proposed. This is separate from specialist review.
Confidence describes the stated assessment; it does not certify expert approval. How review works.
Research description
The property flags phases for which radiocarbon ranges overlap substantially, old-wood or residual-sample effects are possible, or typological boundaries are sharper than the absolute evidence.
