of the Pigeon Point drumlin, Clew Bay, Ireland. They found that the bulk of the landform, which displays a classical drumlin shape, consists of silty-clayey diamicton showing evidence of deformation, hydrofracturing and comminution. The unit is interpreted
as a sub-glacial traction till/comminution till. It is concluded that glacitectonic processes, notably differential bedrock weathering and thrusting, have played a key role in the formation of this drumlin.

formed here towards the end of various glaciations, and are filled with sediments that in their lower part are fluvioglacial, not fluvial. Later on, those sediments became altered by various processes, mainly by glacitectonics. (L'A.).
