The chemical composition of granitic gneisses and sparagmitic meta-sediments in the Glomfjord region, Northem Norway. Norsk geol. tidsskr. 48, 365-380, 1968. New analyses of sparagmitic meta-sediments and granitic gneisses are presented from the Glomfjord region. The sparagmites are distinct in composition from the gneisses and they show a less systematic variation in composition than the latter. The chemical evidence supports the field evidence that the gneisses have not been produced by granitisation of the sparagmites, but form part of the Precambrian basement on which the sparagmites were deposited.
