Dislocated Quaternary marine and glacilacustrine sediments are demonstrated at two localities in East
Greenland. The deformations comprise thrust floes, overturned folds and tension fractures formed by
glacier overriding in the Holocene. At one locality there is evidence of ponded drainage and pro- and
subglacial deformation of unfrozen sediments. Glacitectonic deformations have not earlier been recorded
from Greenland
