Fra det indre af Finmarken
(NGU (36), Journal article, 1902)Forkortet: The solid rock. In the region between Bjørnstad (NW corner of the map) and the first geological boundary line (dotted on the map) there are mostly sheared, quartzitic, feldsparbearing sandstone, lying more or ... -
Fra det nordøstlige af Jotunfjeldene
(NGU (37), Journal article, 1904)Forkortet: This mountain region forms the highest part of Southern Norway between latitudes 61\u00B0 28' and 61\u00B0 46' N. The two highest mountains in Norway, Gald- høpiggen and Glittertinden, lie within the territory. ... -
Fra Hardangervidden I
(NGU (34), Journal article, 1902)Forkortet: The map on p.29 shows the chief geological divisions. Brøgger has found that the succession of strata in the Hårteigen Mountain has been as follows. 1. Lowermost, lying on old granite, Alum-schist (in Hulberget ... -
Fra Hardangervidden II
(NGU (34), Journal article, 1902)Forkortet: The present author has chiefly worked in the middle part of the district. The sections on p.37 show granitic rocks that have been pushed over the Cambro- Silurian phyllite along thrust-planes. The picture on ... -
Fra Hardangervidden III
(NGU (34), Journal article, 1902)Forkortet: The border-lines on the southwestern and southern part of the map on p.29 are to be attributed to Mr.Bjørlykke, who had a very wild region to explore. His photo, reproduced on p.63, shows veins of granite in ... -
Fra høifjeldsstrøget mellem Haukeli og Hemsedalsfjeldene
(NGU (36), Journal article, 1903)Foredrag: This mountainous region is situated between latitudes 59\u00B0 50' and 61\u00B0 N in the highest parts of the country. In 1900 Reusch, Bjørlykke and the writer surveyed the western and southern parts of this ... -
Fracture-generated permeability and groundwater yield in Norway
(NGU Bulletin (439), Journal article, 2002)The transport of groundwater in bedrock is largely determined by interconnected fractures and their apertures. The conditions by which fractures become interconnected are thus of primary importance in understanding ... -
From Archaean to Proterozoic on Hardangervidda, south Norway
(NGU Bulletin (433), Journal article, 1997) -
Front variations of outlet glaciers from Jostedalsbreen, western Norway, during the twentieth century
(NGU Bulletin (431), Journal article, 1996)The record of glacier-front position changes at 15 individual outlet glaciers from Jostedalsbreen during the twentieth century is presented and interpreted. A specific pattern of glacier-front oscillations is recognised, ... -
Gabbroic and quartz dioritic intrusions in gneisses on southern Askøy, West Norwegian Caldonides.
(NGU (270), Journal article, 1971)Light- and dark-coloured biotite gneisses and in part amphibole gneisses, of supracrustal origin have been intruded by a Precambrian basic pluton. Later a quartz diorite was intruded into the basic rocks. By assimilation ... -
Gabbrokonglomeratet i Sjodalen.
(NGU (195), Journal article, 1956)The Gabbor Conglomerate in Sjodalen. The area dealt with in the present paper is a part of the valley of the river Sjoa (Sjodalen) in central southern Norway, about 61o42'N and 9o18'E. An account of the general geology of ... -
Geochemical changes accompanying mylonitisation of granite at the base of the Helgeland Nappe Complex, Nord-Trøndelag, central Norway
(NGU Bulletin (446), Journal article, 2006)A progressive conversion of megacrystic granite into mylonites at the base of the Helgeland Nappe Complex in the Caledonides of central Norway is reflected in microstructural, textural and modal changes. These mylonites ... -
Geochemical evidence in support of sedimentary precursors to Proterozoic sillimanite-bearing rocks, Vest-Agder, South Norway
(NGU Bulletin (446), Journal article, 2006)Sillimanite-bearing alumina-rich schists and gneisses from three different areas within the Agder region in southern Norway are interpreted as having sedimentary precursors, transformed during deep-seated Sveconorwegian ... -
Geochemical modelling of natural geo-/hydrochemical stratification dominated by pyrite ocidation and calcite dissolution in a glaciofluvial Quaternary deposit, Gardermoen, Norway.
(NGU Bulletin (434), Journal article, 1998)The PHREEQC geochemical model has been used to reproduce on a geological time scale an abrupt shift between an oxic and an anoxic zone, in the Gardermoen glaciofluvial delta deposit. Groundwater in the aquifer has a major ... -
Geochemical provinces in the northern parts of the Baltic Shield and Caledonides: preliminary results.
(NGU Bulletin (403), Journal article, 1985)Forkortet. The geochemistry of the continental crust of the northern part of the Baltic Shield and adjoining Caledonides has been investigated by analysis of till and stream sediment samples collected at a density of sample ... -
Geochemistry and palaeogeographical setting of greenstone units on Frosta peninsula, Nord-Trøndelag, Central Norwegian Caledonides
(NGU Bulletin (450), Journal article, 2010)Volcanic and high-level intrusive rocks of the Støren Nappe exposed on the west coast of Frosta peninsula occur in two, distinct, magmatic units; the bimodal Fånes complex and the metabasaltic Granheim greenstone. North ... -
Geochemistry and petrogenesis of trondhjemites and granodiorite from Gauldalen, Central Norwegian Caledonides
(NGU Bulletin (437), Journal article, 2000)In the Gauldalen district of Central Norway, three varieties of trondhjemite cutting rocks of the Gula Complex have been distinguished on the basis of nuances of colour and field relationships. The high Al2O3, Rb and Sr, ... -
Geochemistry and petrology of dolerite dykes of probable late Caledonian age from the outer Sunnfjord region, West Norway.
(NGU (363), Journal article, 1981)Major and trace element abundances from dolerite dykes in the outer Sunnfjord region show an averall compositional similarity to continental tholeiites. The dyke rocks exhibit a fractionated nature, especially with respect ... -
