Abstract

The raised beach in Church Bay on Rathlin Island, Co. Antrim is shown to be a solitary gravel barrier thai formed around 12000 to 13000 years ago as a result of erosion of the chalk outcrops to the south. The beach sediments exposed in a back barrier gravel pit show the progressive development of a coastal structure under occasional washover. The barrier suggests a sea-level several metres above present, which is consistent with late-Midlandian evidence from elsewhere on the Irish coast, but suggests major land-sea changes must have occurred between Rathlin and the northwest shelf of the British Isles.
