A Tectono-stratigraphic transect across the central Scandinavian Caledonides
Organizers: Peter Robinson and David Roberts, Geological Survey of Norway, Trondheim; David Gee, Uppsala University, Sweden
The purpose of this trip is to give geoscientists from other countries a comprehensive view of the Scandinavian Caledonides in this central region, by making a transect across the mountain belt from the orogenic front near Östersund, Sweden to Trondheim and Ålesund in Norway. We will start in the clearly defined lower thrust sheets and follow them westwards deep into the hinterland region of severely attenuated tectono-stratigraphic units and eclogite-facies and UHP metamorphism. The coverage will be general in nature, but with a strong emphasis on important results from paleontology, structural fabrics, metamorphic petrology, geochronology and geophysics, and will be designed to attract all kinds of geoscientists with an interest in the evolution of mountain belts and a desire to experience this location first hand. The only major tectonostratigraphic unit not seen on this excursion is the Uppermost Allochthon, which may be seen on a pre-meeting trip in north-central Norway.
