A beryllium-magnetite correlation in the Hørtekollen-Grubeås area, Buskerud, Norway, and its use for beryllium prospection.
(NGU (223), Journal article, 1963)A helvite-magnetite mineralization at Hørtekollen was studied for its beryllium and magnetite contents. Statistically, a close correlation between the magnetite and the beryllium contents was found to occur. Therefore a ... -
A continous seismic and magnetic profile across the Norwegian Continental Shelf and Vøring Plateau.
(NGU (300), Journal article, 1973)The upper part of the continental slope in the Storegga region dips at approximately 30\u00B0 and from the foot of this feature an undulating surface continues to the base of the slope. In some places these undulations ... -
Aeromagnetic and gravimetric interpretation of regional structural features in the Caledonides of West Finnmark and North Troms, Northern Norway.
(NGU Bulletin (419), Journal article, 1990)Forkortet.Interpretation of aeromagnetic and gravity data from Finnmark and North Tromshas resulted in a new map of depth to Precambrian basement. The integratedinterpretation of the data shows that the Seiland Igneous ... -
Aeromagnetic basement complex mapping north of latitude 62°N, Norway.
(NGU (316), Journal article, 1975)The Geological Survey of Norway (NGU) has conducted aeromagnetic measurements over Norway since 1959, and to date approximately 90 % of the country has been covered with 435,000 line kilometres of such measurements. Since ... -
Aeromagnetic investigations on the continental shelf of Norway, Stad-Lofoten (62-69°N).
(NGU (266), Journal article, 1970)An aeromagnetic isogram map based on measurements by Norges geologiskeundersøkelse 1965-67 is presented and interpreted.The map reveals several interesting geological features, the most important ofwhich is the existence ... -
De alluviale gullforekomster i indre Finnmark.
(NGU (236), Journal article, 1966)The first find of alluvial gold in Finnmarken was made by inspector (bergmester) Tellef Dahll in 1866 in sand from a small river named Nitusjokka near Karasjok. During the following 5 years gold deposits were found in all ... -
Geofysisk undersøkelse innen kartbladet Smøla (med geofysisk kart M 1:50 000).
(NGU (330), Journal article, 1977)Aeromagnetic and gravimetric surveys have been carried out within the map-sheet, and a map (scale 1:50 000) accompanies the description. An interpretation of the main geophysical anomalies is presented. -
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 ... -
Interpretation of the Proterozoic Kautokeino Greenstone Belt, Finnmark, Norway from combined geophysical and geological data.
(NGU Bulletin (425), Journal article, 1993)Processed images of aeromagnetic, gravimetric and topographical data and geological maps combined with EM helicopter measurements, petrophysical data and digitised geological field observations have been used in a geological ... -
