A Kl Ar age of 380 ± 5 Ma has been obtained from an intrusive body in the· southern part of the North Greenland Fold Belt in Peary Land. This age dates the first major deformation event in the North Greenland Fold Belt, and it is inferred that a correlation exists between the North Greenland Fold Belt and the Northern Ellesmerian Fold Complex of the Arctic Canadian archipelago. The dating furthermore casts serious doubt on the proposed genetic link between the intrusive rocks of the southern part of the North Greenland Fold Belt and the Late Cretaceous Kap Washington volcanics and the N-S trending dyke swarms W of Peary Land.
