    Sammanfattning : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. LÄS MER

  3. 2. Planetary Mineral Database Development and Validation of Spectra Classification Methods

    L3-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Sam Taylor; [2022]
    Nyckelord :;

    Sammanfattning : Future astronauts working on planetary bodies need to have a detailed understanding of their surroundings and get real-time feedback from their tools to properly explore these bodies. As such, the ESA PANGAEA course trains astronauts in astrobiology and geology to help with their research as well as providing analytical techniques for sampling and scientific analysis in the field.

    Sammanfattning : Lithium represents one of the strategic elements for the rest of the 21st century due to its increasing demand in technological applications. Therefore, new efforts should be focused on the optimization of mineral characterization processes, which link the ore properties with its behaviour during downstream processes. LÄS MER

  7. 5. Metodundersökning : utvärdering av borrhålskartering avseende kalksten för industriella ändamål, File Hajdarbrottet, Slite, Gotland

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Fredrik Nylén; [2017]

    Sammanfattning : Abstract: On the north–eastern part of Gotland, in Slite, a mapping method has been tested in the Silurian bed-rock. The aim of the study was to develop a new mapping method adapted for industrial purposes on behalf of Ce-menta AB. The developed method is based on chemical analyses of drill cuttings and geophysical surveys. LÄS MER
