Glaciomarine sediments of the Isle of Man as a key to late Pleistocene stratigraphic investigations in the Irish Sea Basin

The northern part of the Isle of Man in the central Irish Sea Basin is identified as a raised marine foreland containing the largest subaerial exposure of last glaciation marine and glaciomarine sediments yet recognized on the British continental shelf. A large push ridge that crosses the foreland identifies a major ice limit. The ridge divides the foreland stratigraphy into a coarsening-upward marine sequence of pelagic muds with dropstones, …
