Preservation of basal-ice sediment texture in ice-sheet moraines

Abstract Ice-sheet moraines near Kangerlussuaq in west Greenland inherit distinctive particle-size distributions from basal ice, although debris structures from the basal ice are commonly destroyed by deposition and resedimentation processes. The abundance of clay and silt in the`dispersed faciesa b...
