En geologisk undersøkelse på den sørøstre del av kartbladet Salangen.
Petrographic and structural investigations were made in a Cambro-Ordovician area of the Caledonides of Northern Norway, situated in Salangen, Troms. The rocks, mainly mica schists rich in biotite and\/or muscovite, are mostly folded and the schistosity is very distinct. This group of rocks also comp...
