Nappe and thrust structures in the Sparagmite region, southern Norway.
(NGU (380), Journal article, 1983)The Osen-Røa Nappe Complex is thrust upon a crystalline basement and a thin autochthonous sediment cover. The nappe complex is characterized by a sole thrust cutting up-section toward the SSE, by flats, ramps and contraction ... -
The Silurian succession of the Oslo Region.
(NGU (384), Journal article, 1983)he marine Silurian succession of the Oslo Region displays agreat variety of mixed clastic and carbonate lithofacies. Maximumthicknesses (< 650 m) and most complete successions are seen in thecentral parts of the region in ... -
Remarks on stratigraphical classification
(NGU (213), Journal article, 1961)One may distinguish between chronostratic (or chronostratigraphical) classification (units with time boundaries) and protostratic classification (with quality boundaries). Protostratic classification embraces biostratic ... -
Leirfallet ved Knivsvik i Hurum 1940.
(NGU (167), Journal article, 1946)In the night preceding to October 11th, 1940, a clay-slide took place by Knivsvik near Drammen. This was a typical clay-slide; some liquid clay (\"Kvikkleire\") flowed down a brooklet called Knivsvikbekken. Most of the ... -
Glacial stadials and interstadials of the Late Precambrian Smalfjord Tillite on Laksefjordvidda, Finnmark, North Norway.
(NGU (358), Journal article, 1980)Three glacial conglomerates and two intervening sandstones in the Smalfjord Formation on Laksefjordvidda were deposited during three glacial episodes and two interstadials, respectively. MOst of the sequence is preserved ... -
Investigations at the south-western border of the Sparagmite Basin (Gausdal Vestfjell and Fåberg Vestfjell), Southern Norway.
(NGU (266), Journal article, 1970)Descriptions are given of lithologies deposited in the original Sparagmite Basin. These rocks can be classified into a parauthochthonous older part and an allochthonous younger unit. Most of the formations of the Sparagmite ... -
Foreløpige meddelelser fra kartbladet Essandsjø.
(NGU (223), Journal article, 1963)A symposis is given of 4-5 weeks of field work in the Sylene area, Sør-Trøndelag, Norway, in the eastern part of the Cambro-Silurian geosyncline of Trondhjemsfeltet. Previous investigations are reffered to. The rocks in ... -
Geochemistry of dolerite and metadolerite dykes from Varanger Peninsula, Finnmark, North Norway.
(NGU (322), Journal article, 1975)Dolerite dykes provide the only manifestation of igneous activity in the thick, Riphean to Lower Cambrian, weakly metamorphosed sedimentary sequence of Varanger Peninsula. Major and trace element abundances and ratios from ... -
Lerfall ved Roel, Innerøy.
(NGU (166), Journal article, 1946)Innerøy is situated on the South-Eastern shore of Borgenfjord, a branch of Trondheimsfjord. The slip occurred in the afternoon of the 24th of April 1937. A road near the beach was destroyed by the slide over a distance of ... -
Origin of plagioclase-megacrysitic, orthopyroxene amphibolites within a Precambrian banded gneiss suite, Flekkefjord area, Vest-Agder, South Norway.
(NGU Bulletin (438), Journal article, 2001)Within a banded gneiss suite belonging to the high-grade Mesoproterozoic Flekkefjord complex in southern Norway, thin lenses of orthopyroxene amphibolites with medium- to large-size plagioclase megacrysts are located at ... -

(NGU (203), Journal article, 1958)Variasjonsdiagrammer av Jotuneruptivdekkenes bergartsserierbekrefter deres primært magmatiske lagdeling, fremkommet ved mere ogmindre komplett, gravitativ differentiasjon. De her publisertediagrammer med tekst er ment som ... -
Petrography and metamorphism in the Precambrian rocks of the Magnor area, S. Norway.
(NGU (246 A), Journal article, 1967)The rocks of the Magnor area comprise various red and grey gneisses, amphibolites and red, unfoliated granites. The gneisses and amphibolites most probably were sediments and basic intrusives, respectively, metamorphosed ... -
