  1. 1. Geochronology of gneisses adjacent to the Mylonite Zone in southwestern Sweden: evidence of a tectonic window?

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :James Davies; [2020]
    Nyckelord :Geochronology; Hallandian orogeny; Mylonite Zone; Sveconorwegian orogeny; U-Pb; Idefjorden terrane; Eastern Segment; B-Bulan; Brobacka; Earth and Environmental Sciences;

    Sammanfattning : The relationship between the Eastern Segment and Idefjorden terrane prior to the Sveconorwegian orogeny has long been debated. Evidence of a common history is minimal and localised; at the same time, the notion that the Sveconorwegian orogeny formed as a result of a collisional event is also disputed. LÄS MER

  3. 2. REE mineralisation and metasomatic alteration in the Olserum metasediments

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Wayne Fullerton; [2014]
    Nyckelord :metasediment; metasomatism; mineralisation; monazite; Olserum; REE; xenotime; Earth and Environmental Sciences;

    Sammanfattning : The Olserum mineralisation is situated in the metasediments of the Västervik formation, which repre-sents the southernmost continental margin of the Svecokarelian Domain. After deposition between 1.88 – 1.85 Ga these sediments were subsided to a depth of about 10 km and intruded by a series of granitoid melts. LÄS MER

  4. 3. P-T evolution of paragneisses and amphibolites from Romeleåsen, Scania, southernmost Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Jan Ulmius; [2013]
    Nyckelord :Romeleåsen; metamorphism; geothermobarometry; pseudosection; Theriak-Domino; P-T path; Hallandian Danopolonian; Sveconorwegian Romeleåsen; metamorfism; geotermobarometri; pseudosektion; P-T-utveckling; halandisk danopolonisk; svekonorvegisk; Earth and Environmental Sciences;

    Sammanfattning : Populärvetenskaplig sammanfattning Vad har berget i Romeleåsen varit med om? Jordskorpan är uppbyggd av ett antal plattor. Vid plattgränser under oceanerna bildas ny skorpa av magma som tränger upp. Oceanplattan kan inte öka i storlek. LÄS MER
