  4. 4. Deglaciation pattern and dynamics in the Bolmen area, southwestern Sweden

    Detta är en avhandling från Department of Quaternary Geology, Lund University

    Författare :Gunnar Andersson; [1998]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geology; backwasting; Debris flow; Oscillation; Gothenburg moraine; cover moraine; Late Weichselian; hummocky moraine; physical geography; Geologi; fysisk geografi;

    Sammanfattning : The Late Weichselian deglaciation of an area in southwestern Sweden was reconstructed by geomorphological, sedimentological and lithostratigraphical methods. The morainic deposits were mapped and classified into three landsystems: Streamlined terrain, hummocky moraine and cover moraine. LÄS MER

  5. 5. Sveconorwegian orogenesis in the southwestern Baltic Shield - Zircon geochronology and tectonothermal setting of orthogneisses in SW Sweden

    Detta är en avhandling från Department of Geology, Lund University

    Författare :Jenny Andersson; Lund University.; Lunds universitet.; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Petrology; Geologi; fysisk geografi; physical geography; Geology; structural markers; augen gneiss; orthogneiss; migmatite; ion microprobe; Pb-Pb evaporation; U-Pb; geochronology; zircon; Sweden; Mylonite Zone; Western Segment; Sveconorwegian orogen; Eastern Segment; mineralogy; geochemistry; Petrologi; mineralogi; geokemi;

    Sammanfattning : The Mylonite zone (MZ) is a prominent late-Sveconorwegian lithological terrane boundary in the SW Baltic Shield along which large-scale crustal block movements took place during the Sveconorwegian orogeny. The southern section of the MZ also defines a conspicuous metamorphic break separating upper amphibolite and high-pressure granulite facies rocks in the parautochthonous Eastern Segment (ES), from middle amphibolite facies rocks in the overlying Western Segment (WS).
