Devonian ages from 40 Ar/39Ar dating of plagioclase in dolerite dykes, eastern Varanger Peninsula, North Norway.
(NGU Bulletin (440), Journal article, 2002)Gas-release spectra derived from the analysis of plagioclase from three geographically distinct but geochemically comparable dolerite dykes from the eastern part of Varanger Peninsula, northern Norway, show similar features ... -
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 ... -
Geologiske undersøkingar på Frøya og Froøyane.
(NGU-Rapport (90.073), Report, 1990)Kartlegging på Frøya og Froøyane har vist at berggrunnen for det meste er samansatt av kaledonske intrusivar som i nokre område innheld xenolittar av metasedimentere bergarter med ukjend alder. På Frøya og i ein del område ... -
Geology of the Fosen Peninsula and Trondheimsfjord Region: a synopsis and excursion guide.
(NGU-Rapport (98.119), Report, 1998)In the first part of the report, a synopsis is presented of the general geology and tectonostratigraphy of this part of Central Norway, with a slightly more detailed account given of the geology of Fosen Peninsula. The ... -
On the tectonic relations of the Devonian complex of the Røragen area, East Central Norway.
(NGU (223), Journal article, 1963)In 1961, by chance, the author observed strata within the Devonian complex at Røragen. As the complex was earlier believed to be faulted only, the athor revisited the area in 1962. In the present paper the field relations ... -
Relasjonen mellom senkaledonsk tektonikk og sedimentasjon ved Hornelens og Håsteinens devon.
(NGU (223), Journal article, 1963)The Old Red in western Norway form very thick \"molasse\" deposits. The Håsteinen district is made up of coarse breccia with an estimated thickness of more than 1000 m and the Hornelen district has mainly sandstone with ... -
Sedimentary, tectonic and metamorphic features of the Devonian of Røragen, Sør-Trøndelag.
(NGU (311), Journal article, 1974)An outline is given of the depositional environment of these Lower Devonian rocks following the discovery of various primary sedimentary structures which have provided some evidence of palaeocurrent directions. Tectonic ... -
Sedimentasjon og tektonisk utvikling i Kvamshestens devonfelt, Vest-Norge.
(NGU (270), Journal article, 1971)The present paper deals with the Devonian rocks of theKvamshesten district of western Norway. A strong E-W folding of thebasement in late-Silurian or early-Devonian was followed by crustaluplift through Lower Devonian. At ... -
Some features of tectonic deformation of Old Red Sandstone sediments on Hitra, west central Norway.
(NGU (370), Journal article, 1981)Minor tectonic structures affecting Downtonian Old Red Sandstone sediments on Hitra indclude folds parasitic to a major syncline, and an associated axial surface spaced cleavage. The cleavage is most prominent in mudstones, ... -
Tectonometamorphic development of Devonian rocks of western Solund, and regional implications.
(NGU-Rapport (99.033), Report, 1999)Many modern accounts of Devonian rocks of western Norway, which emphasise the extensional phenomena affecting them, tend to ignore or gloss over the deformation and metamorphism which these rocks have suffered during ... -
The Gudbrandsdalen Antiform - a major Late Caledonian structure
(NGU Bulletin (433), Journal article, 1997) -
The relationship of sedimentation to tectonics in the Solund Devonian District of southwestern Norway.
(NGU (259), Journal article, 1968)The Solund district of southwestern Norway contains a maximum preserved stratigraphic thickness of 5,200 meters of coarse conglomerate with less amounts of intercalated sandstone. The deposits are thought to be Middle ... -
The Thermal Springs of Bockfjord, Svalbard - Hydrogeochemical Report
(NGU-Rapport (97.183), Report, 1997)In July 1996, a team of researchers visited the \"Troll\" and \"Jotun\" springs of northern Svalbard to carry out mapping and sampling activities. The main conclusions of the hydrochemical survey will be reported in ...
