A 3-dimensional, time-variant, numerical groundwater flow model of the Øvre Romerike aquifer, southern Norway
(NGU Bulletin (426), Journal article, 1994)Using the U.S.G.S. MODFLOW code, coupled with a Penman-Grindley type recharge model, it has been possible to produce a transient, 3-dimensional groundwater flow model of the Øvre Romerike aquifer. The MODFLOW code was ... -
A 6-ka climatic cycle during at least the last 50,000 years.
(NGU Bulletin (445), Journal article, 2005)The distribution of 264 dates in the interval 12,000-50,000 years BP from terrestrial and raised marine sediments from ic-free intervals in Norway shows a fairly strong cycle with a period of c.6 thousand years. The cycle, ... -
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 buried late MIS 3 shoreline in northern Norway - implications for ice extent and volume
(NGU Bulletin (450), Journal article, 2010)Buried beach gravel in northern Norway represents a late Middle Weichselian\/Marine Isotope Stage (MIS) 3 shoreline and indicates a significant late MIS 3 ice retreat. An age of c. 50-31 cal ka BP, or most likely c. 35-33 ... -
A clay sample from Tangen brickwork.
(NGU (200), Journal article, 1957)En leirprøve fra Tangen teglverk nær Fredrikstad, samlet av E. Kvernstrøm og innsendt til Norges geologiske undersøkelse av H. A. Sand, ble underkastet røntgenundersøkelse (Per Chr. Sæbø), kornstørresesfordeling og ... -
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 ... -
A copper-zinc mineralization in Trolldalen, Lofoten, Northern Norway.
(NGU (228), Journal article, 1964)From the previous it is most likely that even separated the various mineralizations in Trolldalen are related and contemporary. Allthough different minerals appear in the different veins, pyrrhotite, chalcopyrite and ... -
A fluidization breccia in granite at Skaget, Svellingen, Frøya.
(NGU (380), Journal article, 1983)The breccia consists of fragmented and comminuted host rock material and small amounts of hydrothermal quartz, epidote, laumontite, ?stilbite, calcite and montmorillonite. At least three brecciation and mineralization ... -
A groundwater vulnerability assessment of the Korgen waterworks, Lillehammer
(NGU Bulletin (427), Journal article, 1995) -
A Late Quaternary correlation chart for Norway.
(NGU (223), Journal article, 1963)A correlation chart is presented containing the stratigraphical results of some selected Norwegian studies in the wide field of Quaternary geology. Studies of plant remains in bogs, pollen investigations, evidence of ... -
A likely Early Ordovician age for the regional penetrative cleavage in the Gaissa Nappe Complex.
(NGU Bulletin (441), Journal article, 2003)Pervasively cleaved mudstones and claystones from two different parts of the Gaissa Nappe Complex in Finnmark wre subjected to Rb-Sr whole-rock analytical investigation. Although neither of the two groups of samples yielded ... -
A new occurrence of gabbro in the Oslo Rift, South Norway
(NGU Bulletin (441), Journal article, 2003)Xenoliths made up of an assemblage of gabbro, diorite and biotite monzonite in syenite and granite and veined by these rocks have been found within a small area at the south end of lake Mykle in the southern part of the ... -
A new Rb-Sr isotopic parameter for metasomatism, At, and its application in study of pluri-fenitized gneisses around the Fen ring complex.
(NGU Bulletin (445), Journal article, 2005)Emplacement of the Fen peralkaline-carbonatitic ring complex 583 Ma ago in the c. 1105 Ma old Telemark gneisses caused mineralogical, chemical and Sr-isotopic changes, i.e., fenitization, in the country rocks. Fenitization ... -
A note on the sulphur composition of chalcopyrite and pyrrhotite from the Moskogaissa mines, Birtavarre, Troms.
(NGU (203), Journal article, 1958)Under et besøk i Oslo sommeren 1956 var prof. A.M. Bateman (Yale Univ., USA) så vennlig a tilby å gjøre en bestemmelse av det stabile svovelisotop-forholdet i prøver fra Birtavarre. Håpet var at en slik bestemmelse kanskje ... -
A petrographical and structural study of the rocks around the Peridotite at Engenbræ, Holandsfjord, Northern Norway. Bjergartene omkring peridotiten ved Engenbræen, Holandsfjord.
(NGU (191), Journal article, 1955)This study is a continuation of the work carried out by S. Skjeseth and the writer in 1952. The present paper only deals with an extremely well-exposed surface 1 km square in front of the retreating Engenbræ glacier. This ... -
A possible basement to the Mesoproterozoic quartzites on Hardangervidda, South-Central Norway: zircon U-Pb geochronology of a migmatitic gneiss
(NGU Bulletin (437), Journal article, 2000)On Hardangrvidda west of the Mandal-Ustaoset fault zone in South Norway, some 80-90% of the crust consists of orthogneisses and foliated and massive granites in this plutonic environment the Mesoproterozoic quartzites of ... -
A post-Caledonian ultrabasic biotite lamprophyre dyke of the island Ytterøy in Trondheimsfjord, Norway.
(NGU (215), Journal article, 1962)A lamprophyre having pronounced alnøitic - kimberlitic affinities is described. It is suggested that the intrusion of the dyke is connected with Permian rift faulting. -
