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

   Kandidat-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

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

   Sammanfattning : 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. LÄS MER

   Sammanfattning : Abstract Mineralogical-mineral chemical characterisation of Nb-Ta-bearingassemblages from the Stripåsen granitic pegmatite, NorbergJens Henriksson The occurrence of Nb-Ta-bearing minerals has earlier been briefly documented inthe Stripåsen granitic pegmatite, Norberg, central Bergslagen. This report describesthe background, preparation and basic characterisation of sampled Nb-Ta-bearingmineral assemblages from this pegmatite. LÄS MER

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

   Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

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

   Sammanfattning : 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. LÄS MER

   Sammanfattning : 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. LÄS MER

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

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

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

   Sammanfattning : 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. LÄS MER
