  1. 6. Characterization of Fe-rich skarns and fluorapatite-bearing magnetite occurrences at the Zinkgruvan Zn-Pb-Ag and Cu deposit, Bergslagen, Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Filip Ivarsson; [2019]
    Keywords : Zinkgruvan; Bergslagen; Magnetite; REE; Broken Hill-type; Skarn; SEDEX;

    Abstract : Zinkgruvan is a stratiform Zn-Pb-Ag and Cu sulphide deposit hosted by Paleoproterozoic strata in southern Bergslagen, Sweden. The deposit underwent medium-high grade regional metamorphism during the Svecokarelian orogeny, including partial melting of the host succession. READ MORE

  3. 7. Hydrothermal alteration and lithogeochemical marker units at the Svärdsjö Zn-Pb-Cu deposit, Bergslagen, Sweden, and their implications for exploration

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Anton Fahlvik; [2018]
    Keywords : Hydrothermal alteration; Lithogeochemistry; Exploration; Bergslagen; Svärdsjö;

    Abstract : In exploration, a lithogeochemical approach can be used to aid the characterisation of rocks surrounding metamorphosed and hydrothermally altered deposits. Accurate description of the geological setting of deposits is crucial for understanding the ore forming processes and identifying targets for exploration. READ MORE

  4. 8. Characterization of the Hydrothermal Alteration around the Björkdal Au Deposit, Skellefte District, Sweden

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Madeleine Erneholm; [2017]
    Keywords : Gold Ore; Mine; Skellefte District; Sweden; Quartz Lode; Hydrothermal Alteration; Petrography; Lithogeochemistry; Intrusion-related Gold;

    Abstract : Sixteen samples from 8 locations within and surrounding the Björkdal mine area in northern Sweden were chosen in order to reevaluate and characterize previous interpretations of the lithology and hydrothermal alteration. Geochemical analysis by ICP-MS was made in order to chemically classify the lithology of the area and petrological studies were made by study of thin sections and core logging. READ MORE

  5. 9. Determining host rock protolith in an altered VMS deposit in the Rävliden area, North Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Zana Mataruga; [2016]
    Keywords : Rävliden; lithogeochemistry; immobile elements; protolith; alteration; Rävliden; lithogeokemi; immobila element; protolit; omvandlingar;

    Abstract : The Rävliden mine is located in the Skellefte district in northern Sweden. In close proximity lays the Kristineberg deposit containing zinc, copper and lead ore which has been mined since the 1940’s. The district is rich in massive sulphide deposits and the mining history can be dated back to the 1920’s. READ MORE

  6. 10. Petrology and lithogeochemistry of the host rocks to the Nautanen Cu-Au deposit, Gällivare area, northern Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Ian McGimpsey; [2010]
    Keywords : geography; geology; petrology; lithogeochemistry; Nautanen Cu-Au deposit; Gällivare; northern Sweden; Earth and Environmental Sciences;

    Abstract : The Nautanen Cu-Au deposit is located 75 km north of the Arctic circle, and 10 km northeast of the town of Gällivare in northern Sweden. Nautanen is just 8 km west of the giant Malmberget apatite-iron ore deposit and 15 km north of one of Europe’s largest copper producers, the Aitik Cu (Au) porphyry deposit. READ MORE
