Abstract
The third and last season of the North-East Greenland project between latitudes 75° and 78°N was completed in July and August 1990. The main aims of the studies in North-East Greenland include compilation of a 1:500 000 geological map sheet covering the area between Grandjean Fjord (75°N) and Jökelbugten (78°N), and regional geological investigations to provide an understanding of the general geology of the region. A preliminary evaluation of the potential for hydrocarbons and mineral resources was included in the project, and took the form of investigations of the onshore remnants of Phanerozoic sedimentary basins (Stemmerik & Piasecki, 1990) and a geochemical exploration reconnaissance.

The third and last season of the North-East Greenland project between latitudes 75° and 78°N was completed in July and August 1990
North-East Greenland is geologicaIly part of the c. 400 million year old East Greenland Caledonian fold belt, which can be traced for over 1100 km along the east coast of Greenland between Scoresby Sund in the south and Kronprins Christian Land in the north (Fig. 1). This fold belt is developed at the eastern border of the Precambrian Greenland shield and includes reactivated Precambrian crystalline complexes and deformed thick Upper Proterozoic - Ordovician sedimentary sequences
The post-Caledonian development was characterised by the formation of sedimentary basins with deposition of thick sequences of Devonian - Lower Permian continental sediments and Upper Permian - Cretaceous mainly marine sediments

(5) Studies of the Quaternary geology in an east-west zone between the outer coast and the Inland Ice, north of Dove Bugt, in order to investigate the history of the region mainly in relation to the late and post-glacial development.
