Geomorphological observations at Kangerdkugssuaq, East Greenland.

Abstract

Updoming is estimated to have occurred about 50 myr ago. Several km of sediments and lavas were eroded off this dome at an early stage exposing the gneissic core, which still stands in alpine peaks up to about 2.7km altitude and dumping ca. 50 000 km3 of sediment on the continental shelf. A brief description of the various types of glaciers, an impermanent, ice-dammed lake and the areas of ice-free land is given. -from Author
