dc.description.abstract | In an earlier geochronology paper in this same journal, discordant U-Pb ages on zircons from a dolerite dyke near Hamningberg, Varanger Peninsula, Finnmark, were interpreted to favour a Vendian (Ediacaran) age of intrusion for this dyke. A re-assessment of this interpretation, and further consideration of the field, geochemical and 40Ar\/39Ar or K\/Ar age characteristics that this dyke shares with other, unmetamorphosed, Devonian-age dolerite dykes in this same region of NE Norway and NW Russia, leads to the conclusion that the Hamningberg dolerite dyke is also most likely of Late Devonian age. | |
