    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : Nicole Flanders; [2023]
    Keywords : ;

    Abstract : A geophysical investigation on the northern part of Utö was carried out between 2020 and 2021 to asses the extent of the iron ore (BIFs) and the iron bearing sulfides that have been surveyed and mined in the past. The survey using analog field equipment combined magnetometry, gravimetry, susceptibility, leveling, density, and thin-section microscopy. READ MORE
