Abstract
The whole region, perhaps except for northem Nansen Land, was covered by the Inland Ice in ?pre-Eemian time. A much younger stage, characterised by fresh moraines at the fjord mouths and along Robeson Kanal, is assigned a Late Weichselian age. Deglaciation began c. 10 000 years B.P. Reworked pre-Holocene shelIs are rather common, and Holocene marine deposits occur sporadieally. The marine limit varies from Co 125 m to c. 60 m.

The critical erratics are Precambrian basement rocks which have a limited exposed outcrop near the Inland Ice margin at the head of Victoria Fjord (Dawes, 1976; Henriksen & Jepsen, 1985), but which probably outcrop widely beneath the Inland Ice along the whole southern margin of the area. The presence of these erratics on hill summits over 800 m within a few kilometres of the north coast, on Hall Land, Nyeboe Land and Wulff Land, indicates that virtuaIly all of the area has been glaciated by the Inland Ice which must have extended out to the shelf edge
Deposits forrned by fjord glaciers, Le. by tongues of ice extending along the fjords from an Inland Ice margin which lay further to the south
Summary
The whole region, perhaps except for northem Nansen Land, was covered by the Inland Ice in ?pre-Eemian time. A much younger stage, characterised by fresh moraines at the fjord mouths and along Robeson Kanal, is assigned a Late Weichselian age. 10 000 years B.P. Reworked pre-Holocene shelIs are rather common, and Holocene marine deposits occur sporadieally. The marine limit varies from Co 125 m to c. In the 1984 field season, parts of the region between Nansen Land and Hall Land were mapped from fixed camps supplemented by helicopter reconnaissance ground stops. These field data provide a frarnework for continuing photogeological and geochronological studies. The data so far suggest the folIowing broad sequence of events
