  2. 1. Precambrian and Caledonian history of Svalbard’s West Ny Friesland Terrane

    Author : Fredrik Hellman; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geologi; physical geography; Geology; Detrital; Zircon; Svalbard; Caledonides; Spitsbergen; fysisk geografi; Petrology; mineralogy; geochemistry; Petrologi; mineralogi; geokemi;

    Abstract : This thesis deals mainly with age-investigations of metasedimentary and magmatic rocks of Ny Friesland, located in the northeastern Svalbard. However, the provenance of quartz-porphyry clasts in a Devonian conglomerate have also been investigated in northwestern Svalbard. READ MORE

  4. 2. Eurasian Arctic Tectonics: Geology of Severnaya Zemlya (North Kara Terrane) and Relationships to the Timanide Margin of Baltica

    Author : Henning Lorenz; David G. Gee; Robert Scott; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Arctic; Severnaya Zemlya; North Kara Terrane; Baltica; bedrock; geology; tectonics; Timanides; Caledonides; Geovetenskap; Earth sciences; Geovetenskap;

    Abstract : The North Kara Terrane (NKT), with Severnaya Zemlya as its main outcrop area, constitutes the Palaeozoic and older rocks of the northern part of the Kara Shelf. Potential field data suggest a continuation into the eastern Barents Shelf. READ MORE

  5. 3. Geophysical studies of the upper crust of the central Swedish Caledonides in relation to the COSC scientific drilling project

    Author : Peter Hedin; Christopher Juhlin; Alireza Malehmir; Bjarne Almqvist; Charles Hurich; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; reflection seismic; collisional orogeny; Scandinavian Caledonides; COSC; scientific drilling; geophysical logging; gravity; magnetics; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : The Collisional Orogeny in the Scandinavian Caledonides (COSC) project aims to provide a deeper understanding of mountain belt dynamics through scientific deep drilling in the central parts of the mountain belt of western Sweden. The main targets include a subduction related allochthon, the basal orogenic detachment and the underlying partially subducted Precambrian basement. READ MORE

  6. 4. Assembly of the Caledonian Orogenic Wedge, Jämtland, Sweden

    Author : Hagen Bender; Uwe Ring; Bjarne SG Almqvist; Rob Strachan; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; collisional orogeny; Scandinavian Caledonides; Seve Nappe Complex; Köli Nappe Complex; in-sequence thrusting; out-of-sequence thrusting; imbrication; nappe stacking; orogenic wedge assembly; Rb–Sr geochronology; rock magnetism; anisotropy of magnetic susceptibility; Geology; geologi;

    Abstract : Collisional orogeny creates the largest mountain belts on Earth. The Caledonides of Scandinavia are a deeply eroded, ancient mountain belt, which today exposes a deep section through the former orogenic interior. READ MORE

  7. 5. The Köli Nappe complex in Tännforsfältet western Jämtland, Swedish Caledonides

    Author : Monica Beckholmen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This dissertation presents the Köli Nappe Complex of Tännforsfältet, an area of some 1200 km2 of volcano-sedimentary eugeoclinal rocks occurring in a shallow synformal basin, the Tännforsen Synform. The rocks have been metamorphosed under greenschist-lower amphibolite facies conditions. READ MORE
