  1. 1. Kinetic interpretation of microstructures in the Gällivare area; implications for deformation phases and related metamorphic events.

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Linnéa Jansson Fagerlund; [2021]
    Keywords : Geology; Northern Sweden; Gällivare; Nautanen Deformation Zone; Fjällåsen Deformation Zone; Microstructures;

    Abstract : The goal of this study was to identify and describe different microstructures observed in samples from two major shear zones in the Gällivare area, namely the Nautanen Deformation Zone (NDZ), and the Fjällåsen deformation zone (FDZ). Thirteen samples were examined during this study. READ MORE

  3. 2. Characterization of Fe-rich skarns and fluorapatite-bearing magnetite occurrences at the Zinkgruvan Zn-Pb-Ag and Cu deposit, Bergslagen, Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Filip Ivarsson; [2019]
    Keywords : Zinkgruvan; Bergslagen; Magnetite; REE; Broken Hill-type; Skarn; SEDEX;

    Abstract : Zinkgruvan is a stratiform Zn-Pb-Ag and Cu sulphide deposit hosted by Paleoproterozoic strata in southern Bergslagen, Sweden. The deposit underwent medium-high grade regional metamorphism during the Svecokarelian orogeny, including partial melting of the host succession. READ MORE

    Abstract : Ädelfors is situated ca 17 km east of Vetlanda, Jönköping County, in the N-S striking Trans-scandinavian igneous belt and is a part of the NE-SW striking 1.83-1.82 Ga Oskarshamn-Jönköping belt emplaced during a continental subduction towards the Svecofennian continental margin. The continental arc hosts the 1. READ MORE

  5. 4. The Metamorphic History of the Helags Mountain Area, Scandinavian Caledonides

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sara Johansson; [2016]
    Keywords : Seve Nappe Complex; Scandinavian Caledonides; metamorphism; monazite geochronology; garnet;

    Abstract : The Scandinavian Caledonides formed as a result of collision between the continents Baltica and Laurentia, in Silurian and Early Devonian time. The evolution of the orogen has been a topic of research since before the turn of the last century. READ MORE

  6. 5. Metamorphic record of monazite in aluminous migmatitic gneisses at Stensjöstrand, Sveconorwegian orogen

    University essay from Lunds universitet/Geologiska institutionen

    Author : Andreas Olsson; [2016]
    Keywords : Monazite; LA-ICP-MS; U-Th-Pb Geochronology; Migmatite; Stensjöstrand; Earth and Environmental Sciences;

    Abstract : Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) has been utilised to investigate the age and chemical composition of two texturally different types of monazite in leucosome and mesosome of polymetamorphic aluminous migmatitic gneisses at Stensjöstrand, Halland. Results of radiometric dating are compared with previously published zircon dates. READ MORE
