Forkortet:The region described is situated in the interior of Northern Norway between66\u00B0 30' and 67\u00B0N, and to the east of the Territory treated in The Geology ofNorthern Helgeland, NGU Nr.62.The stratified rocks, occurring here, are mica-schist, crystalline limestone,gneiss and schistose quartz-rock. Of these the mica-schist has the greatestextension (see annexted map). The direction of the strike is for the most partN-S to NNE-SSW or parallel with the mountain-range. But near to the borders ofthe great granitic intrusions, it bends along the border-lines of the eruptivesThe mica-schist is graylish and of pronounced, schistosity. It is speckled withbrown garnets, and in some places also with brown staurolite (see Fig.2,pl.VIand Fig.1,pl-VII). Crystalline limestone and marble cover a considerable area(see map). The limestone contains generally a small percentage of magnesia. Inseveral places also layers of dolomite are intercalated in the limestoneseries, mainly in its upper parts. Much of the limestone is gray-coloured andyields a fetid odour when blown. But here also occur white, yellow and redvarieties of the limestone. It contains in part argillaceous matter and passesinto a calcareous schist. The mineral of tremolite occurs often in the dolomite
