Resumé

Aeromagnetic data available from both regional and detailed surveys are shown to be valuable in the interpretation of the geology within the Nuuk region. The regional data that cover the entire Nuuk region provide information on large-scale crustal segments and the data are useful in the structural interpretation of the geology. In general, a good correlation between mapped geological units and the magnetic responses are observed. In several areas, the magnetic data are indicative of so far unmapped geological structures. Although the regional data provide valuable information, considerably better resolution of the magnetic field variations and thereby the geology can be obtained from the detailed surveys that are flown at low altitude but within smaller areas

The regional aeromagnetic data has been modelled jointly with gravity data from the region. A boundary between the Akia terrane and the Akulleq terrane is found to dip towards northwest.
