Abstract

K/Ar age determinations have been carried out on three dyke samples from a suite of post-tectonic mica lamprophyres in the inner parts of Danells Fjord and Påtussoq (Andrews et al., 1971 & in prep.). The dykes were intruded through a metamorphosed supracrustal sequence and in turn transected by an east-west trending dolerite in Danells Fjord.
