A section across the Norwegian Caledonides; Bodø to Sulitjelma.
(NGU (260), Journal article, 1969)Between coastal regions near Bodø and the relatively well-known Sulitjelma area on the Norwegian-Swedish border a number of metasedimentary sstructural units have been distinguished lying above an apparently region-wide ... -
Aeromagnetic basement complex mapping north of latitude 62°N, Norway.
(NGU (316), Journal article, 1975)The Geological Survey of Norway (NGU) has conducted aeromagnetic measurements over Norway since 1959, and to date approximately 90 % of the country has been covered with 435,000 line kilometres of such measurements. Since ... -
Age determination from the Trondheim Region Caledonides, Norway: a preliminary report.
(NGU (288), Journal article, 1973)Twenty-four potassium-argon age determinations have been made on metamorphic minerals and whole-rocks (phyllites) from the Caledonides of the Trondheim region, Norway. Nineteen of the apparent ages fall between 438 and 402 ... -
An example of granitization in the central zone of the Caledonides of Northern Norway. Et eksempel på granittisering i den sentrale sonen av Kaledonidene i Nord-Norge.
(NGU (184), Journal article, 1953)A brief outline of the geology of the Holandsfjord area is given and the structural evolution and the granitization processes are discussed. It is concluded that the large masses of granite overlying the paragneisses may ... -
Basement Gneiss doming the Uppermost Allochthon in the Bogøy area of Steigen, Nordland, Norway.
(NGU Bulletin (414), Journal article, 1989)Steigen lies geographically within the Uppermost Allochthon, which was emplacedduring the Scandian phase of the Caledonian orogeny. A tectonized boundaryseparates a basement culmination of Precambrian granite-gneisses from ... -
Bidrag til Finmarkens geologi
(NGU (84), Journal article, 1918)The present paper is a result of investigations carried out in the most northern district of Norway, during the summers 1914-17, the total amount of time spent in Finnmark being 23 weeks. The studies have been confined to ... -
Brachiopods and trilobites from the Ordovician Lower Hovin Group (Arenig/Llanvirn), Hølonda area, Trondheim Region, Norway: new and revised taxa and paleogeographic interpretation
(NGU Bulletin (414), Journal article, 1989)Thirteen brachiopod and 13 trilobite taxa in 15 collections from the Hølonda Limestone and Nyplassen Formation of the Lower Hovin Group confirm the late Arenig-early Llanvirn age of these rocks. New monotypic and apparently ... -
Caledonian structural geology and tectonics of East Hinnøy, North Norway.
(NGU Bulletin (396), Journal article, 1984)Rocks of east Hinnøy comprise three Caledonian tectonic elements: (1) parautochthonous pre-Caledonian crystalline basement (Lofoten block); (2) allochtonous Precambrian gneisses, probably derived from the Lofoten block, ... -
Caledonian sulphide deposits and minor iron-formations from the southern Trondheim region, Norway.
(NGU (340), Journal article, 1978)Within the southern and central parts of the Trondheim region of the Norwegian Caledonides a great number of small, stratabound cupriferous pyrite deposits are confined to mafic metavolcanics of the Gula, Støren and Fundsjø ... -
Den kaledonske fjellkjede i Norge. The Caledonian mountain chain in Norway.
(NGU (189), Journal article, 1954)The Caledonian mountain chain in Norway: One of the most important and interesting problems in Scandinavian geology is the structure of the Caledonian Mountain chain, which runs through the country from Hardanger to the ... -
Devonian tectonic deformation in the Norwegian Caledonides and its regional perspectives.
(NGU (380), Journal article, 1983)Late-Caledonian megascopic folds deforming the Old Red Sandstone sequences of southern Norway are mostly synclines of E-W to NE-SW trend and E to NE plunge. Thrusts along the eastern and southern margins of several ORS ... -
Die Gesteine der Halbinsel Strand. Beiträge zur Metamorphose und zum Aufbau der kambro-silurischen Gesteine des Stavanger-Gebietes II
(NGU (267), Journal article, 1970)This second report of investigations in the Stavanger district gives a description of the geology, and the structural deformations in a cambro-Silurian rock sequence of metamorphosed argillaceous sediments, sandstone, ... -
Die Gesteine der Inseln des zentralen Boknfjords. Beiträge zur Metamorphose und zum Aufbau der kambro-silurischen Gesteine des Stavanger-Gebietes III
(NGU (267), Journal article, 1970)A metamorphic series of Cambro-Silurian sediments have been investigated in the Boknfjord area (SW-Norway) by mapping and petrographical studies. The lower division was found to be a weakly metamorphosed sequence of manifold ... -

(NGU (373), Journal article, 1982)Greenstone volcanites of Middle Ordovician age from the Snåsavatn area of the Central Norwegian Caledonides can be divided into two distinctive groups on the basis of their geochemical patterns. The bulk of the lavas sampled ... -
Distribution of some trace elements in different benefication fractions from the Bleikvassli pyritic lead-zinc ore body, Nordland.
(NGU (300), Journal article, 1973)The distribution of some minor and trace elements at different stages of sulphide ore benefication in the Bleikvassli ore-dressing plant, has been studied using neutron activation analysis. Silver, gold, antimony and ... -
