3. 2. Characterization of Cu-mineralized carbonate veins in the Alta-Kvænangen Tectonic Window, Norway

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

   Författare :Ellen Svens; [2024]
   Nyckelord :Greenstone belt; IOCG; Svecokarelian orogeny; Alta-Kvænangen Tectonic Window; Bergmark anticline;

   Sammanfattning : The Alta-Kvænangen Tectonic Window is part of a regional greenstone belt that formed around 2.3 Ga – 2.0 Ga. The Bergmark anticline in the area has gone through greenschist to amphibolite facies metamorphism and hosts Cu, Co and Au mineralizations in hydrothermal veins, albite felsite and chemical traps.

   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

5. 4. Styles of mineralization in the Nautanen IOCG deposit

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geovetenskap och miljöteknik

   Författare :Nils Edblom; [2020]
   Nyckelord :Nautanen; Aitik; Gällivare; Norrbotten; IOCG; NDZ; nautanen deformation zone;

   Sammanfattning : Nautanen is an IOCG (Iron Oxide Copper Gold) deposit located in northern Sweden, 10 km north-east of the town Gällivare in the county of Norrbotten. It was mined for copper for seven years in the early 1900´s and is presently explored by Boliden Mineral AB. The deposit sits within a package of shoshonitic andesites of the Porphyrite group.

7. 5. Mineralogical and Geochemical characterization of the Fe-Cu-Occurrence and associated Hanging wall and Footwall Alteration halo of the Viscaria D-Zone, Kiruna District, Northern Sweden

   Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

   Författare :Madelen Estholm; [2019]
   Nyckelord :Alteration halo;

   Sammanfattning : Northern Norrbotten County is one of the three major ore producing districts in Sweden. Based on the predominance of epigenetic Cu-Au and Fe-oxide mineralization this region is regarded as a typical IOCG province. The massive to layered Viscaria Cu-deposit is proposed to be a VMS deposit of Besshi-type and is unique in deposit type of the region. LÄS MER
