  1. 6. A Petrological Investigation of the Host Rocks for the Kuj-Kiirunavaara Ore

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Holger Sandberg; [2018]
    Keywords : Kiirunavaara; optical mineralogy; hydrothermal alteration; electron microprobe; Kiirunavaara; optisk mineralogi; hydrotermal omvandling; elektron-mikrosond;

    Abstract : The Kiirunavaara mine hosts one of the world’s largest apatite-iron ore mineralisations. This ore body has been subject to large amounts of research as well as extensive mining. The ore body is situated between the syenitic foot wall and the rhyodacitic hanging wall, of which consists of differing mineralogy and characteristics. READ MORE

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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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. READ MORE

  4. 8. Petrographic study of high-grade gneisses, Halland area

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : Diana Carlsson; [2014]
    Keywords : ;

    Abstract : This is a petrographic study of high-grade gneisses in the Halland area, Sweden. During bedrock mapping by the Swedish Geological Survey, three principal petrographically distinct gneiss domains have been recognized: the Skene, Varberg, and Halmstad domain. READ MORE

  5. 9. Ore Petrography and Geochemistry of some REE-bearing Fe-oxide Assemblages from the Idkerberget Deposit, Bergslagen, Sweden

    University essay from Institutionen för geovetenskaper

    Author : Fredrik Sahlström; [2012]
    Keywords : Idkerberget; Petrography; Geochemistry; REE; Apatite-Iron Oxide Ore;

    Abstract : The mine dumps of Kiruna-type apatite-iron oxide ore in Bergslagen, South Central Sweden, contain elevated amounts of rare earth elements (REEs). A recently started project at Uppsala University has been initiated to study these ores among others in order to document occurrences of REEs and other critical elements in the mine dumps. READ MORE

  6. 10. Variation in rock quality between metamorphic domains in the lower levels of the Eastern Segment, Sveconorwegian Province

    University essay from Lunds universitet/Geologiska institutionen

    Author : Linda Lundgren; [2012]
    Keywords : rock quality; microDeval test; Los Angeles test; studded tyre test; quantitative analyses; Los Angelesvärde; kulkvarnsvärde; microDevalvärde; bergkvalitet; kvantitativa analyser; Earth and Environmental Sciences;

    Abstract : Populärvetenskaplig sammanfattning: Variationer i bergkvalitet hos gnejser i Halland, sydvästra Sverige För att kunna förklara variationer i bergkvalitet hos hög metamorfa gnejser i Halland, sydvästra Sverige, har tolv gnejser från området undersökts både kvantitativt och kvalitativt. Tanken är att de kvalitativa resultaten, fält- och tunnslipsbeskrivningar, ska kunna användas som prospekteringsverktyg för aggregat till väg och järnväg. READ MORE
