  1. 1. Geological 3D Modelling ofthe File Hajdar Quarry, Slite

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Friberg Nils; [2023]
    Nyckelord :3D-modelling; Cementa; limestone; resistivity; Gotland; 3D-modellering; Cementa; kalksten; resistivitet; Gotland;

    Sammanfattning : Located on the island of Gotland, Sweden, the File Hajdar limestone quarry is an important locality for domestic cement production. With depositional settings generally related to shallow sea carbonate ramps, the lithologies encountered on File Hajdar range from reef-associated limestone units to more basinal deposition of marls.

  3. 2. Electrolytic Reduction of Iron Oxides in Molten Salt with a Mineralogical Investigation of Magnetite Ore of Tapuli

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

    Författare :Elina Fernö; [2023]
    Nyckelord :Iron reduction; trace element analysis on magnetite ore; molten salt electrolysis; sodium hydroxide electrolyte; NaOH; greenhouse gas; carbon dioxide; CO2; green ironmaking; Järnreduktion; spårelementanalys på magnetitmalm; smältelektrolys; elektrolys i natriumhydroxid; NaOH; elektrolyt; växthusgas; koldioxid; CO2; grön järnframställning;

    Sammanfattning : This master's thesis covers an investigation of the reduction behavior of different iron oxides when electrolytically reduced with molten salt electrolysis (MSE). The tested iron oxides were wüstite (FeO), hematite (Fe2O3), magnetite (Fe3O4) and magnetite ore concentrate from the Tapuli deposit in Pajala, Norrbotten, Sweden. LÄS MER

  4. 3. 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.

  5. 4. Geologisk karaktärisering av den kambriska Faluddensandstenen i Östersjön och dess lämplighet för koldioxidlagring

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Kaisa Bengtsson; [2023]
    Nyckelord :Koldioxidlagring; djupt liggande akvifer; Faludden; St. Sutarve-2018; CO2-storage; deep saline aquifers; Earth and Environmental Sciences;

    Sammanfattning : The Geological Survey of Sweden (SGU) has spent several years investigating the Swedish bedrock to find suitable bedrock for geological storage of carbon dioxide. Deep saline aquifers are considered to have the greatest potential, and the Cambrian Faludden Sandstone subcropping in the Baltic Sea east of Gotland, shows great potential as a storage aquifer.
