Detection of potential pathways for contaminants into the Päijänne Tunnel in Finland
(NGU Bulletin (439), Journal article, 2002)The potable water for a million people residing in the Helsinki metropolitan area is conveyed from Lake P\u00E4ij\u00E4nne along the 120 km-long P\u00E4j\u00E4nne Tunnel. Information on the hydrogeology of the tunnel is ... -
Determination of major and trace elements in rocks employing optical emission spectroscopy and X-ray fluorescence.
(NGU (322), Journal article, 1975)An optical emission spectrometric method for major element determination and an X-ray fluorescence method for the determination of trace elements are described. The first method combines a tape machine with a direct reader ... -
Development of minor late-glacial ice domes east of Oppdal, Central Norway
(NGU Bulletin (441), Journal article, 2003)Glacial striations and ice-marginal forms such as lateral moraines and meltwater channels show that a major north-westerly-directed ice flow invaded the Oppdal area prior to the Younger Dryas (YD) Chronozone. Through the ... -
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 ... -
Diatom stratigraphy related to Late Weichselian sea-level changes in Sunnmøre, Western Norway.
(NGU (380), Journal article, 1983)In sediment cores from four small basins from 44 to 26 m above sea-level, the boundaries between marine, brackish and lacustrine sediments are precisely identified through their distinct diatom stratigraphy. In all basins ... -
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 ... -

Disparate geochemical patterns from Snåsavatn greenstone, Nord-Trøndelag, Central Norway.
(NGU (373), Journal article, 1982)Greenstone volcanites of Middle Ordovician age from the Snåsavatn area of the Central Norwegian Caledonides can be divided into two distinctive groups on the basis of their geochemical patterns. The bulk of the lavas sampled ... -
Distribution of 30,000 year-old sand deposits in the northern North Sea.
(NGU Bulletin (424), Journal article, 1993)The northern North Sea Plateau represents mainly a coastal sedimentary accumulation towards the north and northeast of thick clay deposits separated by thin sand layers. Regional mapping on this flat plateau has revealed ... -
Distribution of rock fragments, grain size and chemical elements of tills in the Lake Mjøsa area, eastern Norway
(NGU Bulletin (453), Journal article, 2014)The Lake Mjøsa area in eastern Norway forms an interesting case to study glacial erosion, transport and deposition because bedrock lithology (source of till) is relatively well known and the Geological Survey of Norway ... -
Distribution of some trace elements in different benefication fractions from the Bleikvassli pyritic lead-zinc ore body, Nordland.
(NGU (300), Journal article, 1973)The distribution of some minor and trace elements at different stages of sulphide ore benefication in the Bleikvassli ore-dressing plant, has been studied using neutron activation analysis. Silver, gold, antimony and ... -
