A copper-zinc mineralization in Trolldalen, Lofoten, Northern Norway.
(NGU (228), Journal article, 1964)From the previous it is most likely that even separated the various mineralizations in Trolldalen are related and contemporary. Allthough different minerals appear in the different veins, pyrrhotite, chalcopyrite and ... -
A fluidization breccia in granite at Skaget, Svellingen, Frøya.
(NGU (380), Journal article, 1983)The breccia consists of fragmented and comminuted host rock material and small amounts of hydrothermal quartz, epidote, laumontite, ?stilbite, calcite and montmorillonite. At least three brecciation and mineralization ... -
Blyglansforekomst på Krækkjeheia, Hardangervidda.
(NGU (200), Journal article, 1957)A lead deposit near Krækkjeheia, Hardangervidda. This short paper presents the main results of an investigation of a galenaspalerite showing on the mountain plateau of Hardangervidda, 160 kms. west of Oslo. The sulfides ... -
Classification of uranium mineralization in Norway.
(NGU (380), Journal article, 1983)NGU has carried out exploration for uranium on a small butvarying scale since the second World War. An attempt is made toclassify types of uranium mineralization occuring in Norway, followinga system based on genetic types. ... -
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 ... -
Norsk arsenmalm og arsenikfremstilling
(NGU (106), Journal article, 1922)The present paper is published by NGU as a report from \"Statens Raastofkomite\" on the emergency production of arsenic during the war when the supplies, ordinarily imported, were cut off. The paper also contains a synopsis ... -
Note on a molybdenite-dolomite-bearing pegmatite in Velfjord, Nordland, Norway.
(NGU (247), Journal article, 1967)A small area of basic gabbro occurs within the granodiorite pluton noth of Velfjord. In this gabbro was found a peculiar pegmatite dike, rich in molybdenite, and composed of quartz, albite, and dolomite as major minerals. -

(NGU Bulletin (433), Journal article, 1997) -
Stratigraphy and major structures of the Grong District, Nord- Trøndelag.
(NGU (354), Journal article, 1979)The rock sequence of the Grong district, which occurs in a depression within the Norwegian Caledonides between two Precambrian massifs, Børgefjell to the north and the Grong culmination in the south, can be divided into ... -
Sulphur isotope composition of the sandstone-lead deposits in southern Norway.
(NGU (380), Journal article, 1983)Samples of galena, pyrite and barite from the Norwegian sandstone-lead occurences in the Gjøvik area and at Osen and Galåa have been analyzed for their sulphur isotope composition. Samples from the Vassbo and Laisvall ... -
The Early Proterozoic Karasjok Greenstone Belt, Norway. A preliminary description of lithology, stratigraphy and mineralization.
(NGU Bulletin (403), Journal article, 1985)The Karasjok Greenstone Belt of Finnmark, Norway, is a sequence of medium-grademetmorphic supracrustal rocks in the northernmost part of the Baltic Shield.Regional mapping has revealed a tectonostratigraphy with the ... -
The geology of the Sorjusdalen area, Nordland, Norway.
(NGU (351), Journal article, 1979)The rocks of the Sorjusdalen area are divided into two distinct tectono-stratigraphic sequences, the lower termed the Pieske\/Vasten Nappe and the upper the Gasak Nappe. The mutual contact of the nappes is imbricate in ... -
