Abstract

Two new 14C dates from a bed of compact inter-tidal peat at Mill Strand, Portrush, are reported and discussed in relation to two previously obtained ages from peat at Dhu Varren, a short distance inland. The date from the top of the Mill Strand peat is statistically inseparable from that of the peat top at Dhu Varren. Together these dates indicate the cessation of peat growth occurred ~6950-6550 cal. BP as a result of sand deposition associated with sea-level rise. However, dated samples from deeper within the respective stratigraphies are not compatible. Their respective ages in relation to their elevations pose a problem of interpretation.
