From central East Greenland, CH ages between 19,500 - >40,000 years B.P. have
been obtained for six samples of marine bivalve shells. The ages seem to be consistent with geological observations and form the basis for a tentative chronology
for the vVeichselian ice age in the region. It appears that the maximum glaciation
during \Veichselian times was attained more than 40,000 years ago, and that
since then ice-free areas have existed. This assumption agrees with evidence of
botanical refugia in the region, and the restricted glacier activity especially during
the Upper Pleniglacial (ca. 30,000-15,000 years B.P.) is explained by a reduced
supply of moisture. A comparison with evidence from other parts of Greenland
indicates that different glacial histories can be expected for different sectors of
the Greenland Inland Ice.
