    Sammanfattning : Too few documentative descriptions exist from the reactivated Proterozoic Nasa Basement window in Sweden. This re-exposed crustal piece predominantly consisting of 1.8 Ga granite and volcanic basement rock lack structural evidences on maps. LÄS MER

  3. 2. A key fold structure within a Sveconorwegian eclogite-bearing deformation zone in Halland, south-western Sweden : geometry and tectonic implications

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Brendan Dyck; [2011]
    Nyckelord :Sveconorwegian; fold nappe; eclogite; Ätran area; U-Pb geochronology; Domino-Theriak; Earth and Environmental Sciences;

    Sammanfattning : Retro-eclogites and associated high-pressure rocks are found in the Ullared area, southwest Sweden. These rocks are evidence of the high-pressure deformation which occurred during the formation of the c. 500 km long Sveconorwegian orogenic belt around one billion years ago. LÄS MER

  4. 3. Tektonostratigrafi och strukturgeologi i Ålkatj-Tielmamassivet, norra svenska Kaledoniderna

    Magister-uppsats, Lunds universitet/Geologiska institutionen
