Depth of extensional faulting on the Mid-Norway Atlantic passive margin.
(NGU Bulletin (437), Journal article, 2000)Two crustal-scale cross-sections of the Mid-Norwegian Atlantic passive margin are discussed. Large W- and E-dipping normal faults relate to extension of the continental crust following the Caledonian orogeny and the ... -

Devonian lavas from Solund, West Norway - field relationships and geochemistry.
(NGU (382), Journal article, 1983)Devonian volcanic rocks in the Hersvik area, Solund, West Norway are represented by two lava flows occuring close to the base of the Devonian conglomerate. They are composed largely of highly flow-banded and brecciared ... -
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 ... -
Diamantførende gneiser på Fjørtoft i den vestlige gneisregionen, Møre og Romsdal
(NGU-Rapport (93.149), Report, 1993)Rapporten presenterer de foreløpige resultatene fra en detaljert kartlegging av et lite område (0,5 x 2 km) med diamantførende gneiser på den nordøstlige delen av Fjørtoft (Nordøyane i Haram kommune, Møre og Romsdal). ... -
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 ... -
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 ... -
En kort redegjørelse for resultaterne fra kortlægningen af Altevatnområdet i Indre Troms.
(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 ... -
Fluid inclusions in post Late Devonian brittle faults in the Sunnfjord region, West-Norway: application to P-T estimates and geothermal gradient reconstructions
(NGU-Rapport (98.009), Report, 1998)Previous structural analysis of post L. Devonian faults in the Sunnfjord region outlined the presence of four populations of faults (Braathen,1998). In the present study, analysis of fluid inclusions hosted by minerals ... -
