K/Ar dates from the Frederikshåb region, southern West Greenland

The dating laboratory at the Institute of Petrology, University of Copenhagen, has made 8 K/Ar age determinations on 7 samples of Precambrian gneiss and granite from the area between Kvanefjord and Neria fjord. The ages reported on here (summarised in table 6) are the first half of a series of K/Ar age determinations to be made covering the region between Frederikshåbs Isblink to the north and Neria fjord to the south.
