    • A beryllium-magnetite correlation in the Hørtekollen-Grubeås area, Buskerud, Norway, and its use for beryllium prospection. 

      Wambeke, L. Van; Verfaillie, G. (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 ...

    • Aeromagnetic basement complex mapping north of latitude 62°N, Norway. 

      Åm, Knut (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 ...

    • Geologic and structural studies around two geophysical anomalies in Troms, Northern Norway. 

      Berthelsen, Asger (NGU (247), Journal article, 1967)
      The geology and structures of two windows (the Mauken and the Divielva windows, see fig. 1) are outlined. For the Precambrian supracrustal rocks of the Mauken window, two formations names and one group name are suggested. ...

    • Granite studies I. A gravity investigation of two Precambrian granites in South Norway. 

      Smithson, Scott B. (NGU (214B), Journal article, 1963)
      The Bouguer gravity anomaly map, based on 778 stations, covers the Precambrian rocks along the southeast coast of Norway from the Oslo region to Kristiansand. The principal features of the map are the low gravity gradient ...

    • Måling av den radioaktive stråling fra bergarter i Norge 

      Siggerud, Thor (NGU (211), Journal article, 1960)
      Kontinuerlig registrering av variasjonen i den radioaktive stråling i Norge er et av resultatene av uranprospekteringen her i landet. Bare den hårde gammastråling er blitt målt og denne er tatt som representativ for total- ...

    • Om bruk av megnetometri ved oljeleting. 

      Åm, Knut (NGU; Skrifter (284; 2), Journal article, 1973)
      The present paper is intended as an elementary introduction for students to the subject of (aero)magnetic prospecting for oil. It covers briefly the following subjects: Magnetism, the geomagnetic field, magnetic anomalies, ...

    • The geological interpretation of the Slidre positive gravity anomaly. 

      Smithson, Scott B. (NGU (228), Journal article, 1964)
      A positive gravity anomaly that occurs in Slidre has an amplitude of 53 mgal and can be separated into two parts. The top of the disturbing body causing the anomaly cannot be deeper than 4 km. Gabbros and mafic gneisses ...

    • Uranundersøkelser i Trøndelag. 

      Siggerud, Thor (NGU (205), Journal article, 1959)
      Undersøkelsen av radioaktivitet i den sedimentære og effusive lagrekken i Trøndelag førte ikke til oppdagelse av noe lag med høyere uran-thoriuminnhold enn normalt for slike bergarter. Det ble ikke funnet noen uranrikning ...
