Granite pegmatite quartz from Evje-Iveland: trace element chemistry and implications for the formation of high-purity quartz
(NGU Bulletin (436), Journal article, 2000)Previous studies imply that granite pegmatites and hydrothermal quartz veins are the most promising igneous repositories of high-purity quartz. This is because quartz from higher temperature geological settings (granites, ... -

Post-Sveconorwegian exhumation and cooling history of the Evje area, southern Setesdal, Central South Norway
(NGU Bulletin (431), Journal article, 1996)Fission track (FT) dating of apatite and sphene from monzonitic dyke rocks in a Middle to Late proterozoic intrusion from the Setesdal region, southern Norway, indicates cooling from intrusion temperatures of the surroundings ... -

The structure and regional setting of the Skei Group, Leka, north-central Norway
(NGU Bulletin (426), Journal article, 1994)The unconformity between the metasedimentary Skei Group and subjacent ophiolite on Leka has important implications for the tectonostratigraphy of the region. As a distinctive marker horizon, it permits correlations within ... -
Geology of the eastern part of the Meråker area.
(NGU (245), Journal article, 1967)Within the mapped area slightly metamorphosed clastic sediments occur, probably of Upper Ordovician and Silurian age. The author describes a metagreywacke-slate association with metaconglomerates and gabbrodiorite sills, ... -
En undersøkelse av kvartære, økostratigrafiske soner i Drammen, på grunnlag av foraminiferer.
(NGU (215), Journal article, 1962)1. The present paper is a report on a quantitative study of the fossil, benthonic foraminifera of Late- and Post-Galcial clay samples from Drammen, Norway. 2. On the basia of their content of foraminifera, it has been ... -

II. Kalkstenshuler i Ranen
(NGU (69), Journal article, 1914)Forkortet: In the district of Rana in Northern Norway (about 66 1\/2\u00B0 N) we have some of the most important layers of limestone and dolomitic limestone in Norway. Grønligrotten (the situation shown on map p.4) is ... -
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 ... -
U-Pb zircon age of 469 +- 5 Ma for a metatonalite from the Kjosen Unit of the Lyngen Magmatic Complex, northern Norway
(NGU Bulletin (428), Journal article, 1995)Two fractions of zircon from a tectonised tonalite from within metagabbro of the Kjosen Unit of the Lyngen Magmatic Complex give a concordant U-Pb age of 469 +- 5 Ma. This is interpreted as a minimum age for the Kjosen ... -
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 ... -
Reconnaissance studies of gneisses, ultrabasites, eclogites and anorthosites in Outer Nordfjord, Western Norway.
(NGU (241), Journal article, 1966)A reconnaissance map of the geology of Outer Nordfjord is presented with some new structural and petrographic data. Mesoscopic folds have often steep axes or curved axial planes which indicate rather plastic type of ... -
