Abstrakt: The article discusses uranium-lead dating for mafic dykes of South East Greenland. Topics discussed include preserved mafic dykes acting as time markers and allowing high-resolution age comparisons of magmatic and extensional histories between cratons, porphyritic texture of Tingmiarmit dyke, and the Melville Bugt swarm sensu stricto, and discovery of porphyritic dykes.
