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. -
Oversikt over bergartene i Sunnmøre og tilgrensende deler av Nordfjord.
(NGU (179), Journal article, 1951)The paper describes the rocks within a large gneiss-area in Sunnmøre district, on the north-west coast of Southern Norway, between Bergen and Trondheim. Besides the dominating granitic gneisses, the rocks consist of remnants ... -
Petrology of differential gabbro sheets in the Altenes tectonic window, North Norway.
(NGU Bulletin (414), Journal article, 1989)The petrography of two differentiated gabbro sheets in the low-grademetamorphic Karelian supracrustal sequence of the Altenes Tectonic Window isdescribed. The intrusion have generally undergone extensive deuteric alter-ation. ... -
Raipas og kaledon i strøket omkring Repparfjord, Vest-Finnmark.
(NGU (183), Journal article, 1952)In the Repparfjord area rocks of the Precambrian Raipas System occur in an inlier, which is directly overlain by allochtonous Caledonian rocks with a tectonic unconformity. Any autochtonous Eocambrian and younger sediments ... -
Rutile associated with eclogites in western Norway and scapolitised gabbros in southern Norway
(NGU Bulletin (427), Journal article, 1995) -
Rutile in eclogites as a mineral resource in the Sunnfjord Region, Western Norway.
(NGU Bulletin (436), Journal article, 2000)The world's resources of the primary titanium raw materials ilmenite and rutile are very large. However, there is a lack of high-grade, high-quality ilmenite deposits as well as good rutile deposits. Particular focus has ... -
Slidre. Beskrivelse til det geologiske gradteigskart
(NGU (180), Journal article, 1951)The greater parts of the area is mountainous, but two deeper valleys are incised in the land mass. The valley of Øystre Slidre cuts the area almost diagonally, the valley of Vestre Slidre lies to the southwest of this. The ... -
Some notes on the Lille Kufjord layered gabbro, Seiland, Finnmark, Northern Norway. Om den lagdelte gabbro-bergart i Lille Kufjord, Seiland, Vest-Finnmark.
(NGU (195), Journal article, 1956)Nyere undersøkelser ved Lille Kufjord på Seiland har vist at vi her har et bergartskompleks av lagdelt (båndet) gabbro med innleirete lag av ultrabasiske bergarter (olovinstein) i den midtre og øvre del av komplekset. ... -
Structure and petrology of the Bergen-Jotun kindred rocks from the Gjendebu region, Jotunheimen, Central Southern Norway.
(NGU (373), Journal article, 1982)The Gjendebu region is located within the Jotun Nappe, highest tectonic unit of the southern Norwegian Caledonides. The structure of the area is dominated by the NE-rending Tyin-Gjende Fault, a major zone of repeated ... -

(NGU (121), Journal article, 1927)The present publication is the first part of a monograph on the Sulitjelma district, containing the sections on physiography, general geology and petrology. In the second part the ore dposits will be described and their ... -
The geology and petrology of the Rognsund intrusion, West Finnmark, Northern Norway.
(NGU (371), Journal article, 1982)The Rognsund intrusion is an early-Caledonian gabbroic body containing an 800 m thick sequence of metamorphosed cumulates. Well-developed rythmic layering is interpreted in terms of both in situ crystallization and deposition ... -
