Morphological and morphometric analyses of drumlin bedforms in the Omagh Basin, North Central Ireland

Description :
The aim of this paper is to describe and compare the morphology and morphometry of diamict-dominated and rock-cored drumlins in the Omagh Basin. Diamict drumlins are mainly of classical or fused type and are found in lowland and basinal locations. Rock-cored drumlins are more morphologically diverse and occur on high-level plateaus and upland flanks. Morphometric analysis reveals both spatial and statistically significant absolute differences between the elongation ratios and orientations of diamict and rock-cored drumlins. This means drumlinization cannot be attributed to a single set of subglacial processes or a single time-interval.
