    • Geodynamics, Geomagnetism and Paleogeography: A 50 Year Celebration 

      Redfield, T.; Smethurst, M. A.; Buiter, S. J. H. (NGU-Rapport (2007.057), Report, 2007)
      Prof. Dr. Trond Helge Torsvik was born on October 12, 1957. He attended the Norwegian Naval Academy before taking degrees from the University of Bergen in 1982 and 1985. In 1991, after a post-doctoral position at Oxford, ...

    • GMAP v.32: Geographic mapping and palaeoreconstruction package 

      Torsvik, Trond; Smethurst, Mark A. (NGU-Rapport (98.002), Report, 1998)
      GMAP is a state of the art computer which performs all processing and plotting tasks usually associated with the storage and presentation of palaeomagnetic pole positions, and generation of palaeographic reconstructions. ...

    • Onshore dating of Late Paleozoic through Mesozoic activities on the eastern and western proto-North Atlantic margins 

      Eide, Elizabeth A.; Torsvik, Trond H. (NGU-Rapport (98.004), Report, 1998)
      This report compiles results from six separate studies linked by the common fact that they address absolute dating of initiation and reactivation of brittle faults, dike emplacement and regional unroofing around the Rift ...

    • Palaeomagnetic dating of fault rocks from Vesterålen, Senja and Troms. Preliminary data 

      Torsvik, Trond H.; Olesen, Odleiv (NGU-Rapport (93.088), Report, 1993)
      A preliminary palaeomagnetic study has been carried out in Vesterålen, Senja and Kvaløya (Troms) in order to furnish temporal constraints on near offshore fault-activity in the Lofoten area. At Senja, two phases of faulting ...

    • Palaeomagnetism of the ophiolite complexes of Meldal, Sør-Trøndelag 

      Mac Niocaill, C.; Ryan, P.D.; Smethurst, M.A. (NGU-Rapport (95.115), Report, 1995)
      A palaeomagnetic investigation of the Early-Ordovician (middle to late Arenig) sheeted dyke complexes of Meldal has revealed a complex multicomponent magneti- zation history. Three components of remanent magnetization were ...

    • Tropical weathering in Norway, TWIN final report 

      Rønning, Jan Steinar; Fabian, Karl; Fredin, Ola; Gellein, Jomar; Husteli, Berit; Magnus, Christian; Solbakk, Terje; Øverland, Jon Arne; Tønnesen, Jan Fredrik; Olesen, Odleiv; Bering, Dag; Brönner, Marco; Dalsegg, Einar (NGU-Rapport (2012.005), Report, 2012)
      The Geological Survey of Norway and the Norwegian Petroleum Directorate established the TWIN Project (Tropical Weathering In Norway) in 2009 to improve the understanding of deep weathering on mainland Norway as well as ...
