      The 'Upper Hovin Group' on the downthrown side of the Horg Fault between the Orkla and Gaula rivers contains rocks of both Late Caradoc and Early Ashgill age, determined from fossils from eight localities. The older part ...

    • Fotogeologi 

      Siggerud, Thor (NGU (205), Journal article, 1959)

    • Four sediment cores from the Continental Shelf outside Trøndelag. 

      Haldorsen, Sylvi (NGU (304), Journal article, 1974)
      Grain size analysis and clay mineral investigations have been carried out. The cores consist of an assemblage of sand, silt and clay, where the clay content is gradually decreasing from the bottom towards the top of the ...

    • Fra det indre af Finmarken 

      Reusch, Hans (NGU (36), Journal article, 1902)
      Forkortet: The solid rock. In the region between Bjørnstad (NW corner of the map) and the first geological boundary line (dotted on the map) there are mostly sheared, quartzitic, feldsparbearing sandstone, lying more or ...

    • Fra det nordøstlige af Jotunfjeldene 

      Rekstad, Johan (NGU (37), Journal article, 1904)
      Forkortet: This mountain region forms the highest part of Southern Norway between latitudes 61\u00B0 28' and 61\u00B0 46' N. The two highest mountains in Norway, Gald- høpiggen and Glittertinden, lie within the territory. ...

    • Fra Hardangervidden I 

      Reusch, Hans (NGU (34), Journal article, 1902)
      Forkortet: The map on p.29 shows the chief geological divisions. Brøgger has found that the succession of strata in the Hårteigen Mountain has been as follows. 1. Lowermost, lying on old granite, Alum-schist (in Hulberget ...

    • Fra Hardangervidden II 

      Rekstad, Johan (NGU (34), Journal article, 1902)
      Forkortet: The present author has chiefly worked in the middle part of the district. The sections on p.37 show granitic rocks that have been pushed over the Cambro- Silurian phyllite along thrust-planes. The picture on ...

    • Fra Hardangervidden III 

      Bjørlykke, Knut O. (NGU (34), Journal article, 1902)
      Forkortet: The border-lines on the southwestern and southern part of the map on p.29 are to be attributed to Mr.Bjørlykke, who had a very wild region to explore. His photo, reproduced on p.63, shows veins of granite in ...

    • Fra høifjeldsstrøget mellem Haukeli og Hemsedalsfjeldene 

      Rekstad, Johan (NGU (36), Journal article, 1903)
      Foredrag: This mountainous region is situated between latitudes 59\u00B0 50' and 61\u00B0 N in the highest parts of the country. In 1900 Reusch, Bjørlykke and the writer surveyed the western and southern parts of this ...

    • Fracture-generated permeability and groundwater yield in Norway 

      Gjesdal, Otilie; Gudmundsson, Agust; Fjeldskaar, Ingrid (NGU Bulletin (439), Journal article, 2002)
      The transport of groundwater in bedrock is largely determined by interconnected fractures and their apertures. The conditions by which fractures become interconnected are thus of primary importance in understanding ...

    • From Archaean to Proterozoic on Hardangervidda, south Norway 

      Birkeland, Anne; Vestin, Jessica; Whitehouse, Martin J.; Sigmond, Ellen M.O. (NGU Bulletin (433), Journal article, 1997)

    • Front variations of outlet glaciers from Jostedalsbreen, western Norway, during the twentieth century 

      Winkler, Stefan (NGU Bulletin (431), Journal article, 1996)
      The record of glacier-front position changes at 15 individual outlet glaciers from Jostedalsbreen during the twentieth century is presented and interpreted. A specific pattern of glacier-front oscillations is recognised, ...
