• Age determinations from the Iveland-Evje area, Aust-Agder. 

      Pedersen, Svend (NGU (300), Journal article, 1973)
      A Rb\/Sr isochron age determination on intrusive granite and monzonite from the Iveland-Evje area gave an age of 1038+- 43 m.y. Biotite from the granite dated by the K\/Ar method gave an age of 845+-60 m.y. These values ...
    • Intrusive rocks of the northern Iveland-Evje area, Aust-Agder. 

      Pedersen, Svend (NGU (322), Journal article, 1975)
      In the northern Iveland-Evje area extensive magmatic activity occurred during the so-called Sveconorwegian igneous period. Two intrusive episodes can be distinguished through apparently they occurred close in time. The ...

      Hansen, Kirsten; Stockmarr, Peter; Fougt, Henrik; Pedersen, Svend (NGU Bulletin (431), Journal article, 1996)
      Fission track (FT) dating of apatite and sphene from monzonitic dyke rocks in a Middle to Late proterozoic intrusion from the Setesdal region, southern Norway, indicates cooling from intrusion temperatures of the surroundings ...
    • The Iddefjord granite: geology and age 

      Maaløe, Sven; Pedersen, Svend (NGU Bulletin (417), Journal article, 1990)
      The Iddefjord granite forms part of the Swedish Bohus batholith and ranges in composition from diorite to granite. The granite consists of 13 individual plutons, and the mechanism of intrusion is related to block subsidence ...
