The geological map Narvik, published in 1950, is briefly described. The bedrock of this map area can be subdivided into autochthonous and allochthonous rocks. The autochthonous rocks comprise the Precambrian (mainly the Rombak window) and overlying conglomerate and sandstone of supposed Lower Cambrian age. An angular unconformity separates the Precambrian from Lower Cambrian. The allochthonous, Caledonian sequence can be subdivided into three thrust units. The main part of this sequence is probably Cambro-Silurian in age, but slices of deformed Precambrian granite occur at the base of the middle unit. Metamorphism of the allochthonous sequence took place in the epidote-amphibolite and almandine-amphibolite facies (up to kyanite grade). A chapter on the economic geology of the area and an excursion guide are included.
