  1. 1. Metamorphic Evolution of the Tjeliken Garnet-Phengite Gneiss, Northern Jämtland, Swedish Caledonides

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Barbro Andersson; [2016]
    Nyckelord :Seve Nappe Complex; Scandinavian Caledonides; high-pressure metamorphism; U Pb zircon geochronology; garnet-phengite gneiss; Seveskollan; skandinaviska Kaledoniderna; högtrycksmetamorfos; uran-bly datering; högtrycksgnejs;

    Sammanfattning : The Tjeliken Mountain in northern Jämtland, central Scandinavian Caledonides is by most authors considered to belong to the Lower Seve Nappe Complex (SNC). However, recently P-T conditions similar to the Middle Seve have been constrained for the eclogite at the top of the mountain, revitalizing the tectonic debate about Tjeliken. LÄS MER

  3. 2. Pressure Temperature Conditions of the Otrøy Opmhacite-Garnet Gneiss, Western Gneiss Region, Skandinavian Caledonides

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Johanna Holmberg; [2015]
    Nyckelord :Western Gneiss Region; Otrøy; gneiss; ultrahigh-pressure metamorphism; Western Gneiss Region; Otrøy; gnejs; ultrahögtrycksmetamorfos;

    Sammanfattning : Garnet-omphacite gneisses from the island of Otrøy situated in Western Gneiss Region (WGR), Norway, Scandinavian Caledonides, were examined within this study. The WGR is one of the planets most studied ultrahigh-pressure (UHP) terranes. The studied gneisses are hosts for UHP garnet peridotites and eclogites. LÄS MER

  4. 3. Sierggavággeskollans strukturgeologiska utveckling : nyckeln till Sareks berggrundsgeologi

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Tobias Hermansson; [2001]
    Nyckelord :geografi. geologi; strukturgeologi; Sierggavággeskollan; Sarek; berggrundsgeologi; Earth and Environmental Sciences;

    Sammanfattning : The Seve Nappe Complex (SNC) in the northern part of the Sarek Mountains, in NW Sweden, is characterized by large metamorphic contrasts between the individual thrust sheets. Eclogite facies and lower greenschist facies rocks are interleaved in a pattern that cannot be explained by normal in-sequence thrusting. LÄS MER
