Geology of the southern part of the Kautokeino Greenstone Belt: Rb-Sr geochronology and geochemistry of associated gneisses and late intrusions.
(NGU Bulletin (403), Journal article, 1985)The southern part of the Kautokeino Greenstone Belt is divided into four volcanic formations separated by sedimentary units. The formation represent a development from Archaean komatiitic sequences to Middle Proterozoic ... -
Geology of the West Troms Basement Complex, northern Norway, with emphasis on the Senja Shear Belt: a preliminary account.

Geology of the western and north-eastern part of the Meråker area.
(NGU (245), Journal article, 1967)A thick metasedimentary sequence together with a volcanic and hypabyssal intrusive complex is described. While strata dip generally westwards it can be shown that the succession is, for the most part, inverted; the discovery ... -
Geology of three dioritic plutons in Velfjord, Nordland.
(NGU Bulletin (423), Journal article, 1992)Dioritic plutons in the Velfjord area of Nordland intrude calc-silicates and migmatitic pelites of the Helgeland Nappe Complex (HNC). The three largest plutons were emplaced in a zone of NNW-SSE regional strike rather than ... -
Geometry and kinematics of extensional deformation along the northern edge of the Rombak Window, Nordland, North Norway.
(NGU Bulletin (415), Journal article, 1989)Deformation along the northern edge of the Rombak Window documents an unusual extensional event during the evolution of a colliosional orogen. The extension occurred along a series of ductile deformation zones that strike ... -
Geometry and vertical extent of the late Weichselian ice sheet in northwestern Oppland County, Norway
(NGU Bulletin (451), Journal article, 2011)The position of the ice margin during the last deglaciation is well known in Scandinavia, in particular during the Younger Dryas (YD) chronozone from when large ice marginal deposits easily can be traced at or close to the ... -
Geophysical and geological interpretation of regional structures within the Precambrian Kautokeino Greenstone Belt, Finnmark, North Norway.
(NGU Bulletin (403), Journal article, 1985)The Kautokeino Greenstone Belt comprises a synclinorium of volcano-sedimentary rocks. This sequence of Early Proterozoic age is situated between two culminations of gneisses. Large areas of the belt have been mapped in ... -
Geophysical measurements in Jeløya.
(NGU (247), Journal article, 1967)As a part of geological\/geophysical student field courses a series of magnetic and gravimetric observations has been carried out at Jeløya. Geological samples have been collected and the physical properties of the samples ... -
Geothermal aspects of hydrocarbon exploration in the North Sea area.
(NGU (316), Journal article, 1975) -
Glacial geology of the area between Jostedalsbreen and Jotunheimen, South Norway.
(NGU (291), Journal article, 1973)Ice movement and the course of deglaciation are reconstructed. The age of and the climate during the deglaciation are discussed in the light of equilibrium line displacement, shoreline positions, pollen analysis and ... -
Glacial geology of Western Troms, North Norway.
(NGU (256), Journal article, 1968)A moraine chronology was established for western Troms. Altogether six main glacial phases were recognised. Several of the phases were radiocarbon dated. Observations were made of the corresponding shore lines, the marine ... -
Glacial geology,deglacition chronology and sea-level changes in the southern Telemark and Vestfold counties, Southeastern Norway
(NGU Bulletin (435), Journal article, 1999)A revised and more detailed deglaciation chronology is presented in the soputhern Telemark and Vestfold, southeastern Norway, based mainly on information and results from mapping projects on the superficial deposits carried ... -
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 ... -
Glasialgeologi og vegetasjonsinnvandring i Indre Nordhordland, Vest-Norge.
(NGU (369), Journal article, 1981)In the area between Hardangerfjorden and Sognefjorden an oldest regional ice movement towards the west has been reconstructed. Younger regional ice movements were towards south-west in the southern parts. Therefore, an ... -
Glidning av Arnebråtveien nr. 30.
(NGU (166), Journal article, 1946)At Arnebråtveien 30 in Aker a sliding of the clayey ground occurred in the evening of May 29th 1936. A road had been built on a foundation of stone. The ground was too weak to stand the weight of the ballast. By a sliding ... -
Glidning og ras av jernbanefyllinger 16-19 april 1937.
(NGU (166), Journal article, 1946)During these days a remarkable number of slides damaged Norwegian railways. April 16th a sandy railway ballast slid out near Skotselv station between Hokksund and Hønefoss. 5000 m3 of ballast slid into the Drammen river, ... -
