  1. 1. Detecting Lithium Brine in Afghanistan Using Spaceborne Hyperspectral Data

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Torpikay Azizi; [2023-08-18]
    Nyckelord :PRISMA Hyperspectral data; lithium mineral deposits; lithium brine-rich deposits; Dashti-e- Nawar; boron deposits; Principal Component Analysis PCA ; supervised and unsupervised classification; spectral matching; spectral profile analysis; visible-near-infrared VNIR ; short-wave infrared SWIR Gypsum; Hectorite; Kaolinite; Lepidolite; lithium carbonate; lithium chloride;

    Sammanfattning : The purpose of this thesis is to utilize hyperspectral remote sensing technology for the identification and evaluation of lithium mineral deposits in Afghanistan. Afghanistan boasts unique geological formations with substantial potential for lithium resources beneath its land crust. LÄS MER

  3. 2. Stratigraphy and palaeoenvironment of the early Jurassic volcaniclastic strata at Djupadalsmölla, central Skåne, Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Per Wahlquist; [2023]
    Nyckelord :volcaniclastic; Djupadalsmölla; CSVP; palynomorphs; early Jurassic; late Pliensbachian; Earth and Environmental Sciences;

    Sammanfattning : From the almost 200 volcanic outcrops in the Central Skåne Volcanic Province (CSVP), only three are of volcaniclastic material. These volcanoclastics, and the transition to the underlying crystalline basement, have been investigated for the first time in a drill core (KBH2) from Djupadalsmölla in order to understand the stra-tigraphy, depositional process, age of deposition, and depositional environment.

  4. 3. Method evaluation for probing DNA sorption to clay minerals : Evaluation of fluorescent and spectroscopic quantification of DNA as well as DNA interactions of Kaolinite and Montmorillonite

    Kandidat-uppsats, Umeå universitet/Kemiska institutionen

    Författare :Oskar Wangdell; [2022]
    Nyckelord :;

    Sammanfattning : The association of DNA/RNA to mineral surfaces is an emerging field with widespread applications from biotechnological solutions to paleogenetics. Evaluating available methods to quantify adsorption will be essential to further investigate how to control and predict loading of DNA onto minerals. LÄS MER

  5. 4. Do Clay Minerals affect the thickener operationin Chuquicamata mine, Calama, Chile?

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

    Författare :Chris Soto; [2020]
    Nyckelord :Mine; clay minerals; mineral processing;

    Sammanfattning : Chuquicamata mine mineralogy has been studied performing both X-Ray Diffraction (XRD) and X-RayFluorescence (XRF) to determine whether there is any influence in the thickener operations. Thetargeted minerals were the clay group because of their detrimental effect on mining operations asmodify the rheology of the suspensions. LÄS MER

  7. 5. Ignimbritenheterna i Barranco de Tiritaña, övre Mogánformationen, Gran Canaria

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Anja Davidson; [2003]
    Nyckelord :geografi; geologi; Ignimbritenheterna; Barranco de Tiritaña; Mogánformationen; Gran Canaria; Earth and Environmental Sciences;

    Sammanfattning : The Upper Mogán formation, the youngest formation of the Mogán Group on Gran Canaria, starts with a basalt, upwards it is dominated by trachytic to comenditic and pantelleritic lavas and ignimbrites. The studied cooling units in Barranco de Tiritaña are green coloured, high-alkali ignimbrites of this formation except for the uppermost unit; witch is a lava belonging to the Fataga Group. LÄS MER
