Abstract

In this paper, the AA. present the integrated use of geomorphological, sedimentological and geophysical techniques as a powerful means to force a breakthrough towards solving the drumlin enigma. They report on investigations of the anatomy 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.
