The sub-Caledonian unconformity on Hjelmsøy - new evidence of primary basement/cover relations in the Finnmarkian nappe sequence.
(NGU (351), Journal article, 1979)A new and important occurence of a primary stratigraphic unconfomity beneath tha Caledonian cover in allochthon of the Finnmarkian segment of the North Norwegian Caledonides is described. This unconformity, on the island ... -
The sulphide deposit of Nordre Gjetryggen Gruve, Folldal, Norway.
(NGU (228), Journal article, 1964)Nordre Gjetryggen Gruve in the Folldal district, southern Norway, is at approximately 62 9'N. latitude and 10 E. longitude. The mining of copper from pyritic ores began in the area in 1748, while the recovery of zinc and ... -
The surface of the inland ice in the Atndalen valley, South-central Norway.
(NGU Bulletin (438), Journal article, 2001)On the basis of different field observations, several authors have discussed the form of the inland ice in southern Norway. In this work, lateral features indicating the upper limit of zones of meltwater drainage marked ... -
The Surna, Rinna and Orkla Nappes of the Surnadal-Orkdal district, southwestern Trondheim
(NGU Bulletin (418), Journal article, 1990)In the district between Surnadal and Orkdal within the 'Gula', the rock sequence between the Late Precambrian metasandstones of the Tingvoll Nappe and assumed Lower Ordovician metavolcanites of the Støren Nappe, three major ... -
The Sveconorwegian magmatic and tectonometamorphic evolution of the high-grade Proterozoic Flekkefjord complex, South Norway.
(NGU Bulletin (434), Journal article, 1998)The Precambrian Flekkefjord complex is situated in the core zone of the Sveconorwegian orogenic belt in south-western Norway, covering the transitional zone between the south Rogaland anorthosite province to the west and ... -
The tectonostratigraphic setting of stratabound sulphide deposits in the southern Trondheim region, Central Norwegian Caledonides.
(NGU Bulletin (412), Journal article, 1988)The large number of mainly massive, polymetallic, stratabound sulphide depositswithin the southern Trondheim region are spatially confined to the differentnappe units of the central Scandinavian Caledonides. The rocks of ... -
The Tectonostratigraphy and structural evolution of the Sitas Area, North Norway and Sweden (68°N).
(NGU Bulletin (416), Journal article, 1989)The Sitas area contains rock derived from the pre-Caledonian Scandinavian craton and from an accreted Caledonian fore-arc complex. These rocks form the par-authocthonous (?) Rombak Complex which can be tied stratigraphically ... -
The terrane concept and the Scandinavian Caledonides
(NGU Bulletin (413), Journal article, 1988)A revised terrane map is presented for the Scandinavian Caledonides, and an outline is given of the principal suspect and exotic terrane-complexes identified outboard from the Baltoscandian miogeocline. The outermost part ... -
The Tromsø-Lyngen glacier readvance (early Younger Dryas) at Hinnøya-Ofotfjorden, northern Norway: a reassessment
(NGU Bulletin (445), Journal article, 2005)Based on radiocarbon dates, marine seismic data, mapping of surficial deposits, observations of marine limits and shoreline correlations, we have documented a considerable glacier readvance during the Tromsø-Lyngen event ... -
The Ulriken Gneiss Complex and the Rundemanen Formation: a basement - cover relationship in the Bergen Arcs, West Norway.
(NGU Bulletin (412), Journal article, 1988)The Ulriken Gneiss Complex (UGC) and its sedimentary cover, the RundemanenFormation, have been investigated. The UGC is a Precambrian migmatite complexwhich suffered strong but heterogeneous reworking during the ... -
Thermal conductivities of some ores and rocks in Norway.
