A 1950 ± 60 Ma Rb–Sr whole-rock isochron age from two Kangâmiut dykes and the timing of the Nagssugtoqidian (Hudsonian) orogeny in West Greenland

Thirteen samples from two Kangâmiut dykes give a Rb–Sr whole-rock isochron age of 1950 ± 60 Ma. This age is interpreted as the age of intrusion of the dykes. The post-dyke Nagssugtoqidian orogeny took place between ca. 2000 and ca. 1800 Ma and can be correlated with the Hudsonian in Canada and the L...
