Geomorphic and sedimentary evidence for patterns of late Midlandian ice retreat in the Tempo Valley, north-central Ireland

Jasper Knight

Abstract


Patterns of late Midlandian ice retreat in the Tempo Valley, north-central Ireland, are reconstructed from field morphological and sedimentary evidence. Ice retreat stages reflect the splitting up of the regional Omagh Basin ice mass into separate Omagh Basin and Clogher Valley components, and the formation and later drainage of glacial lakes which are controlled by the mutual interactions of these ice masses. The Tempo Valley area illustrates some generic problems in reconstructing ice retreat stages in Ireland, including the historical overemphasis of the presence of end-moraines, the possibility of ice lobe interactions following ice sheet division, and the likelihood of ice stagnation as a major mode of deglaciation.
