Geomorphic evidence for patterns of late Midlandian ice advance and retreat in the Omagh Basin

Jasper Knight


Field mapping of late Midlandian-age glacial landforms in the Omagh Basin, north-central Ireland, reveals complex and superimposed bedform patterns. On the basis of this field evidence, stages of glaciation and regional-scale ice retreat are reconstructed. Bedform patterns suggest that (1) bedform shaping took place in several temporally-distinct phases within the overall late Midlandian glacial cycle; and (2) ice centres were mobile and changed their basal thermal and hydraulic characteristics throughout the glaciation.
