Six Younger Granite localities showing normal and reverse magnetizations in equal proportion have given a Jurassic palaeomagnetic pole position ϕ=62.5°N, Λ=241.6°E; (Fisher's precision parameter (k)=27.8 and α95=13°). Individual palaeopole-positions have also been obtained for a Cretaceous pyroclastic rock and for two Pleistocene basalt flows.
