Directions of ice flow during the last glaciation in counties Meath, Westmeath and Cavan

Auteur :
MEEHAN, R.T.

Description :
Ice flow direction indicators in north-west County Meath and adjacent parts of Westmeath and Cavan are described. Drumlins, striae, roches moutonnées, and other streamlined features, as well as till fabrics, suggest a general flow during glacial maximum of north-west to south-east when combined with erratic carriage data. Analysis of the configuration of ice marginal moraines and subglacially deposited esker ridges deposited during glacial retreat, as well as till fabric analysis of deglacial sediments, suggest a more complicated retreat of ice.
