  1. 6. Formation of Sulphides in the Canadian High Arctic Large Igneous Province; Testing the Influence of Sedimentary Rocks

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Erika Hagerfors; [2018]
    Nyckelord :LIPs; HALIP; SIMS; sulphur isotopes; Ni-Cu-PGE ores; environmental deterioration; LIPs; HALIP; SIMS; svavelisotoper; Ni-Cu-PGE malmer; klimatförändring;

    Sammanfattning : Large Igneous Provinces (LIPs) form during short-lived pulses of extensive magmatic activity. LIPs are known for their ability to affect global climate as well as for their Ni-Cu-PGE ore potential. LÄS MER

  3. 7. Ore mineralogy and silver distribution at the Rävliden N volcanogenic massive sulphide deposit, Skellefte district, Sweden

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Simon Johansson; [2017]
    Nyckelord :Rävliden N; Boliden Mineral AB; Volcanogenic massive sulphide deposit; Ore mineralogy; Silver; Remobilisation;

    Sammanfattning : The Rävliden North deposit (Rävliden N) is a volcanogenic massive sulphide (VMS) deposit in the western part of the Skellefte district, northern Sweden. The district is one of Sweden’s major metallogenic provinces with a significant amount of VMS deposits. LÄS MER

  4. 8. Mineraliseringar utmed REE-linjen i sydvästra Bergslagen

    Kandidat-uppsats, Uppsala universitet/Berggrundsgeologi

    Författare :Henrik Linnros; [2014]
    Nyckelord :REE-mineraliseringar; REE-linjen; Bergslagen; Sulfidmikroskopering; SEM-EDS; ArcGIS;

    Sammanfattning : This paper briefly summarizes Bergslagen as a bedrock province in order to give background to the genesis and presence of REE-bearing minerals (short for Rare Earth Elements) in the region. These mineralizations mainly occur along the REE-line, a line aproximately a hundred kilometers in length between Norberg in the north and Nora in the south with a width of a few kilometers. LÄS MER

  5. 9. Mikroskopering av opaka faser - en studie från Skyttgruvan, Falun.

    Kandidat-uppsats, Institutionen för geovetenskaper

    Författare :Marcus Brismo Ploetz; [2013]
    Nyckelord :Malmmikroskopering; Sulfider; Bergslagen;

    Sammanfattning : In nature there are about 4,500 minerals identified. These can roughly be divided into two groups, opaque phases and non-opaque phases, with the exception that some opaque phases also may act as a non-opaque phase in different circumstances. The division is made on the basis of the optical properties. LÄS MER

  7. 10. Mineralogisk och malmpetrografisk studie av disseminerade sulfider i rika och fattiga prover från Kleva

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Andreas Björk; [2013]
    Nyckelord :disseminerad malm; mineralisering; Kleva; koppar-nickel; copper nickel mineralization; disseminated ore.; Earth and Environmental Sciences;

    Sammanfattning : The Kleva copper-nickel sulphide mineralization in Jonkoping County, southeastern Sweden, is categori-sed as an elongated mafic pluton. In this study, ore microscopy and quantitative chemical analysis using SEM -EDS have been used to describe the relative abundance and distribution of sulphides and iron oxides in disseminated samples.
