Early Proterozoic (c 2000-1900 Ma) crustal structure of the northeastern Baltic Shield: tectonic division and tectogenesis.
(NGU Bulletin (403), Journal article, 1985)Recent structural investigations in the Precambrian of northern Finnish Lapland and Norwegian Sørvaranger and their extrapolation into the neighbouring Kola Peninsula have stablished that the northeastern part of the Baltic ... -

(NGU (277), Journal article, 1972)An outline of the stratigraphy and tectonics of an areasituated across the Caledonian thrust front south of Altevatn, northernNorway, is presented. The lithologies are described and it is shownthat the stratigraphy of the ... -
Epigenetisk koppermineralisering på Finnmarksvidda.
(NGU (203), Journal article, 1958)In the Precambrian rocks of Finnmarksvidda, one big copper deposit, Biddjovagge, and a series of small sulphide occurrences are located. The sulphides are pyrite, chalkopyrite and phyrrhotite, in some places also bornite ... -
Evolution structurale de la region Nisser - Vråvatn (Norvege meredionale). (The precambrian rocks of the Telemark area in south central Norway no. VIII. Strucutral development of the Nisser-Vråvatn region.)
(NGU (266), Journal article, 1970)Tectonic and petrographic studies of the Precambrian rocks in the Nisser-Vråvatn region of Telemark have led to the recognition of the following principal features: (1) The basement of the \"Telemark suite\" does not appear ... -
Fabrics and structure of metamorphic flagstones and implications for industrial quality
(NGU Bulletin (436), Journal article, 2000)Metamorphic flagstones are characterised by a regularly spaced mica foliation separated by quartzo-feldspathic domains, along which the rocks can be cleaved into commercial slabs. In the thrust nappes of the Scandinavian ... -
Geologi og petrografi på Nord-Karmøy.
(NGU (247), Journal article, 1967)The athor gives a description of rocks and tectonics on the northern and central part of the island of KarmThe athor gives a description of rocks and tectonics on the northern and central part of the island of Karmøy, ... -
Geologiske og petrografiske undersøkelser i Modumfeltet.
(NGU (235), Journal article, 1966)Geological mapping of part of the Modum area, the northernmost part of the Kongsberg-Bamble area in the Precambrian of southern Norway, was carried out. The different rocks are described, and metasomatic processes which ... -
Geologiske undersøkelser i sørlige Helgeland og nordlige Namdal.
(NGU (254), Journal article, 1967)Cambro-Silurian rocks with large intrusive masses cover most of the area. In the south-westernmost part there are also deeper lying rocks. This part is referred to as the basal gneiss region, while the rest of the area is ... -
Geology and structure of Gjerby, Nordland.
(NGU (370), Journal article, 1981)The island of Gjerøy is made up of acid gneisses with subordinate mixed gneisses which are tightly interfolded with banded gneisses and associated metasediments. The early tight folds are refolded to produce a large-scale ... -
Geology and structure of the Beito Window, Valdres.
(NGU (327), Journal article, 1976)Three groups of Caledonian nappes sit directly on Precambrian gneisses. The lowest nappe consists of generally upward-facing parautochthonous or allochthonous Cambro-Ordovician quartizites and phyllites. The middle nappe ... -
Geology and structure of the Bjøllånes area, Rana, Nordland.
(NGU (343), Journal article, 1978)The field relationships of rock groups of three tectonic units from the area west of the Lønsdalen basal massif are outlined and the lithologies and mineral assemblages are described. Chemical analyses of marbles and ... -
Geology of the Meråker area as a key to the eastern part of the Trondheim region.
(NGU (245), Journal article, 1967)The present paper deals with a discussion of the main tectono-stratigraphical problems of the eastern Trondheim region. Based on detailed studies made in the Meråker area in the last three summers and available manuscript ... -
Geology of the Minor Bergen Arc, West Norway.
(NGU Bulletin (416), Journal article, 1989)Detailed mapping of the Minor Bergen Arc has revealed the presence of a variety of highly deformed rocks of different origin and age. Three rock units have been separated and named. The Nordåsvatn Complex comprises deformed ... -
Geology of the western and north-eastern part of the Meråker area.
(NGU (245), Journal article, 1967)A thick metasedimentary sequence together with a volcanic and hypabyssal intrusive complex is described. While strata dip generally westwards it can be shown that the succession is, for the most part, inverted; the discovery ... -
Geometry and kinematics of extensional deformation along the northern edge of the Rombak Window, Nordland, North Norway.
(NGU Bulletin (415), Journal article, 1989)Deformation along the northern edge of the Rombak Window documents an unusual extensional event during the evolution of a colliosional orogen. The extension occurred along a series of ductile deformation zones that strike ... -
