3D modelling of gravity and magnetic data in the Trøndelag Platform
(NGU-Rapport (2006.082), Report, 2006)Confidential to 31.12.2008The report presents a 3D model of the entire mid-Norwegian margin, with special emphasis on the Trøndelag Platform. Based on the interpretation of OBS profiles, long-offset seismic reflection and ... -
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.

A study of large-scale basins and comparison to the Eastern Barents Sea basins
(NGU-Rapport (2006.081), Report, 2006)Detailed study of the gravity field and the isostatic state of the Barents Sea Region shows that the Eastern Barents Sea basins are not typical rift basins. They show distinctive features as large wavelengths, high ... -
Action map for tunnel planning, Oslofjord - Telemark region: Mapping deeply weathered weakness zones
(NGU-Rapport (2016.015), Report, 2016)Joints and fractures were weathered during a sub-tropical climate regime and thus may contain smectite and kaolinite. The presence of such minerals prohibits groundwater flow in fracture and fault zones. The clay-bearing ... -
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 ... -
Assessment of Geophysical Anomalies near Langvatnet, Lunner, Oppland Fylke
(NGU-Rapport (2001.046), Report, 2001)In June, 1997 and July, 2000, two separate helicopter geophysical surveys were carried out - one over an area in the vicinity of Gran, and the second over an area immediately west of Hurdalsjøen. The purpose of the surveys ... -
Automatisering av petrofysiske målinger.
(NGU-Rapport (87.148), Report, 1987)Magnetisk remanens ble tidligere målt med et manuelt instrument, et \"Oerstedmeter\", som ved hjelp av fire målesonder på et målestativ måler små magnetfelt som avleses på et viserinstrument. Dette instrumentets funksjoner ... -
