Abstract
The Geological Survey of Greenland (GGU) initiated in 1964 a 1:500000 mapping programme to produce a general overview of the onshore geology of all the ice-free areas of Greenland. So far 10 of a total of 14 planned map sheets have been published, and one additional sheet for which field work has been completed is under compilation. Most of Greenland is therefore now covered by map sheets of this series and only three areas remain to be covered: in North-West Greenland (sheet 6), in eastern North Greenland (sheet 9) and in East Greenland (sheet 11). Eastern North Greenland (map sheet no. 9; Fig. 1) is the target of the present project, with planned field work from 1993–1995. The first season (1993) was used for logistical preparation and geological reconnaissance in advance of the more intensive field work in the two following seasons (1994–95).

The Geological Survey of Greenland (GGU) initiated in 1964 a 1:500000 mapping programme to produce a general overview of the onshore geology of all the ice-free areas of Greenland
The map sheet covers the region between JOkelbugten (78°N) in North-East Greenland and northern Kronprins Christian Land (81 °N) in eastern North Greenland (Fig. 1)
This region lies within the northern part of the East Greenland Caledonian fold belt and is dominated by geological units and problems which have already been encountered during earlier mapping projects to the north and south
Summary
The Geological Survey of Greenland (GGU) initiated in 1964 a 1:500000 mapping programme to produce a general overview of the onshore geology of all the ice-free areas of Greenland. The map sheet covers the region between JOkelbugten (78°N) in North-East Greenland and northern Kronprins Christian Land (81 °N) in eastern North Greenland (Fig. 1). This region lies within the northern part of the East Greenland Caledonian fold belt and is dominated by geological units and problems which have already been encountered during earlier mapping projects to the north (sheets 7 and 8; Henriksen, 1992) and south (sheet 10). On the basis of these aerial photographs and ground control points established by the Kort- og Matrikelstyreisen (National Survey and Cadastre - formerly the Geodetic Institute), a new set of topographical maps at a scale of 1: 100 000 with 100 m contours has been drawn at GGU for the entire map sheet area to serve as a basis for the field investigations
