  1. 1. Pressure, temperature and time constraints on tectonic models for southwestern Sweden

    Author : Eric Austin Hegardt; Göteborgs universitet.; Gothenburg University.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sveconorwegian; Gothian; Hallandian; U‐Pb zircon ion probe dating; Sm-Nd garnet dating; thermobarometry; continental subduction; Eastern Segment; Median Segment; Western Segment;

    Abstract : In this work, a number of key localities have been investigated in detail in order to provide precise constraints on models for the tectonic evolution of southern Sweden. The new data presented in this thesis show that there are large differences in terms of pre-Sveconorwegian tectonic evolution between the Eastern and Median-Western Segments situated on either side of the Mylonite Zone, a major shear zone as well as a structural and lithological boundary.

  2. 2. Geochemical Development of Proterozoic Granites in the SW Baltic Shield

    University dissertation from SMC, Box 839, SE-981 28 Kiruna, Sweden

    Author : Kirsten Holme; Lunds universitet.; Lund University.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; principal component analysis; granite classification; magma evolution; magma genesis; granite; Eastern Segment; Western Segment; Southwestern Swedish Gneiss Complex; Sweden; Sveconorwegian Orogen; Petrology; mineralogy; geochemistry; Petrologi; mineralogi; geokemi; Geology; physical geography; Geologi; fysisk geografi;

    Abstract : The plutonic rocks in the Western Segment of the Southwestern Swedish Gneiss Complex show a distinct geochemical evolution. The 1.6 Ga Åmål granitoids and Slottsbron migmatites are a quartz dioritic to granodioritic, calc-alkaline rock suite with smooth, but somewhat fractionated, REE and other trace-element patterns.

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

    University dissertation from Department of Geology, Lund University

    Author : Jenny Andersson; Lunds universitet.; Lund University.; [2000]
    Keywords : 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;

    Abstract : Popular Abstract in Swedish Mylonitzonen (MZ) är en kraftigt framträdande rörelsezon i den sydvästra Baltiska urbergskölden (sydvästra Skandinavien) som löper från Varberg i söder till trakterna av Eidsvol (Norge) i norr. Den sammanfogar urbergsblock av olika ålder och ursprung vilka även har skilda geologiska utvecklingshistorier. READ MORE

  4. 4. Proterozoic crustal evolution in southcentral Fennoscandia

    University dissertation from Department of Geology, Lund University

    Author : Karin Appelquist; Göteborgs universitet.; Gothenburg University.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transscandinavian Igneous Belt; TIB; Eastern Segment; Habo Volcanic Suite; Malmbäck Formation; U-Pb zircon ion probe dating; Nd isotopes; geochemistry; Hallandian; Danopolonian;

    Abstract : The Transscandinavian Igneous Belt (TIB) and the Eastern Segment of the Southwest Scandinavian Domain reflect advanced stages of continental growth within the Fennoscandian Shield. The relationship between the two units is not clear, mainly because N-S trending shear zones of the Protogine Zone transect the border zone. READ MORE

  5. 5. Giant cell arteritis. Epidemiological, morphological and molecular genetic studies

    University dissertation from Göteborg

    Author : Vigdís Pétursdóttir; Göteborgs universitet.; Gothenburg University.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Giant cell arteritis; temporal artery; aorta; epidemiology; atrophy; calcification; estrogen receptor a; morphometry; immunocytochemistry; Western blot; molecular genetics;

    Abstract : Giant cell arteritis (GCA) is a chronic inflammatory disorder of unknown etiology, affecting large and medium-sized arteries, predominantly in postmenopausal women. Its pathogenesis is probably multifactorial. Several studies suggest that GCA is an antigen-driven disease. READ MORE
