On kink-zone development and metamorphic differentiation in the low-grade schists of Norwegian Sulitjelma.
(NGU (247), Journal article, 1967)The common minor scale kink-zones of upper levels of the Furulund schists of eastern Norwegian Sulitjelma generally do not occur in conjugate pairs: usually only the member with northwest dipping axial plane is developed ... -
On numerical AMT profiles and sounding curves over some twodimensional structures.
(NGU-Rapport (86.042), Report, 1985)AMT apparent resistivity sounding curves have been caculated above some two-dimensional horizontal, dipping and vertical conductors in av host rock. The calculations have been made using a finite element computer program ... -

On the form and mode of emplacement of the Herefoss granite.
(NGU (214A), Journal article, 1963)Det geologiske kart over S.Ø. Aust-Agder er dominert av to nesten sirkelrunde granittmassiver, Herefossgranitten (Birkelandsgranitten) og Grimstadgranitten (Fevikgranitten). Et kart over den geologiske omgivelse av disse ... -
On the formation of a carbonate-bearing ultrabasic rock at Kviteberg, Lyngen, northern Norway.
(NGU (205), Journal article, 1959)An area of crystalline dolomite, schists, and gneiss including an ultrabasic body at 60 degrees 35' N and 20 degrees 18' E is described petrographically and structurally. The ultrabasic rock contains enstatite, olivine, ... -
On the gneisses from a part of the north-western gneiss area of Southern Norway.
(NGU (173), Journal article, 1949)The north-western part of Southern Norway is an area mainly of gneisses, formerly regarded as entirely of Archean age. In later years a number of writers have maintained that parts of the gneisses are Caledonian migmatites ... -
On the occurrence of overbank sediment in Denmark. Report from a field excursion in Denmark, 23. May 1991.
(NGU-Rapport (91.205), Report, 1991)Observations made on a field excursion indicate that overbank sediment exists an can be sampled in large parts of Denmark. -
On the presence of minerals of the linnaeite in some copper ores from the Raipas formation of Northern Norway.
(NGU (200), Journal article, 1957)Two minerals of the linnaeite series, A3S4, have been identified and examined in ores from two localities in the Alta district of Finnmark. Their compositions show them to be siegenite and carrollite, respectively. Associated ... -

On the tectonic relations of the Devonian complex of the Røragen area, East Central Norway.
(NGU (223), Journal article, 1963)In 1961, by chance, the author observed strata within the Devonian complex at Røragen. As the complex was earlier believed to be faulted only, the athor revisited the area in 1962. In the present paper the field relations ... -
On the variolitic structure.
(NGU (223), Journal article, 1963)The article presents detailed descriptions of the variolitic structure in selected minor intrusions and lavas. The evidence indicates that the varioles formed by liquid segregation rather than by spherulitic crystallization. -

Onshore - Offshore Resistivity studies. Basement resistivity at the Frøya High
(NGU-Rapport (2005.032), Report, 2005)As part of the prospecting activities of the oil company PERTRA at \"The Frøya High\", the Geological Survey of Norway (NGU) was asked to provide resistivity values of the underlying basement rocks. PL321 is considering ... -
Onshore dating of Late Paleozoic through Mesozoic activities on the eastern and western proto-North Atlantic margins
(NGU-Rapport (98.004), Report, 1998)This report compiles results from six separate studies linked by the common fact that they address absolute dating of initiation and reactivation of brittle faults, dike emplacement and regional unroofing around the Rift ... -
Opdyrkning af lerfaldet i Værdalen
(NGU (14), Journal article, 1894)A great land-slip occurred along the river in the Værdalen valley (east of the Trondhjemsfjord) on the 19th of May 1893. Mr. Werenskiold has analysed the earths, clay and sand, from the landslip-region, and on basis of ... -
Operations of Subsea Systems (SOSS) - sea bed data from the physical test site in the Trondheimsfjord
(NGU-Rapport (2011.024), Report, 2011)A shallow water area east of Trondheim harbour in the Trondheimsfjord has been used as test site to study the impact of towed bottom gear on seafloor sediments in the frame of the SOSS project (Safe Operations of Subsea ... -
