  1. 1. Calculating the combined elemental composition of spodumene using La_ICP_MS in thin_sections samples from Europe.

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

    Författare :Maximilian Körtge; [2023]
    Nyckelord :Lithium minerals; Spodumene; Trace-elements; La-ICP-MS; Mineral processing; Geochemistry;

    Sammanfattning : The study gives a broad background to understand the high demand of lithium batteries in the coming years, especially in Europe. The goal of the study is to use La-ICP-MS to analyse spodumene samples from different lithium deposits in Europe to get a better knowledge of the contents of trace elements in spodumene. LÄS MER

  3. 2. PGE Geochemistry and Mineralogy of Dunite, Chromitite, and Laterite Samples from the Acoje Ophiolite Block, Philippines

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Michelle Dossey; [2023]
    Nyckelord :PGM; PGE; laterite; limonite; chromitite; dunite; platinum group minerals; platinum group elements; Acoje; Philippines;

    Sammanfattning : Ni-laterites have the potential to become unconventional ore deposits for platinum group elements (PGE). This study was conducted to determine enrichment trends of PGE as a result of the Ni-laterization process. LÄS MER

  4. 3. Syn-Magmatic Deformation Structures in the Slaufrudalur Pluton, East Iceland

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Chun Hei Ho; [2023]
    Nyckelord :Granite; Iceland; magma chamber; magmatic microstructure; melt fraction; mush; pluton; rheology; strain; syn-magmatic deformation;

    Sammanfattning : Structures and deformation mechanisms of magmatic rocks are controlled by rheology. An increase in melt fraction can weaken a rock body and localises significant amount of strain. This interplay between rheology, melting and deformation in a magma reservoir, however, is not always clearly documented in literature. LÄS MER

  5. 4. A geological investigation on bedrock suitability for mineral carbonation conducted in the south central part of Sweden

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

    Författare :Edvard Pearson; [2023]
    Nyckelord :Mineral carbonation; geological investigation; Åsensbruk; Falun; Grums; Öje; Skutskär;

    Sammanfattning : Increasing global temperatures due to anthropogenic emissions of greenhouse gases is one of our times most dire and urgent challenges to overcome if we are to achieve a sustainable healthy planet. The primary way of accomplishing this is by reducing the amount of released greenhouse gases. LÄS MER

  7. 5. Silver Mineralogy and Modes of Occurrence at the Silver Hart Deposit, South East Yukon.

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

    Författare :Michael Ives-Ruyter; [2023]
    Nyckelord :Canada; Yukon; silver; lead; zinc; galena; sulfosalt; sulfur isotope;

    Sammanfattning : The Silver Hart property is a high grade silver-lead-zinc deposit consisting of polymetallic vein style, manto (carbonate replacement) style, and skarn type mineralization. Host rock consists of calcareous and non-calcareous sediments of the Cassiar Platform, mainly biotite schists, limestone units, and the monzogranite unit of the Cassiar Batholith. LÄS MER
