      Green, Trevor H.; Jorde, Knut (NGU (270), Journal article, 1971)
      Moskenesøy, Lofoten, forms part of the Lofoten-Vesterålen Precambrian high grade granulite metamorphic province. The dominant basal rock type of the island is a porphyroblastic monzonitic gneiss interbanded with, and grading ...

      Siedlecka, Anna; Roberts, David (NGU Bulletin (452), Journal article, 2012)
      Logging of >800 metres of drillcore from a borehole on Båtsfjordfjellet, Varanger Peninsula, revealed a succession of very low-grade, metasedimentary rocks which are assigned to specific Neoproterozoic formations recognisable ...
