Stratigraphical age. The granite intrudes the Vilddal Series (Middle Devonian) and is unconformably covered by the unfossiliferous Kap Franklin Series, which itself is followed by the Randb61 Series (Middle Devonian). The granite is one of a series of ' la te Caledonian' intrusive rocks of which a pegmatite elsewhere (HN-7b , not stratigraphically related), was dated as 394m.y.; (adopted age = 395 -4xom.y.). The 'main Caledonian' orogeny, based on five scattered samples of metamorphic rocks, was given as 42o to 4oom.y. The end of the main orogeny from one sample was 4o5 4xom.y.
