  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. Mineralogical Study of Manganese Bearing Skarn Minerals and Manganese Content in Magnetite in the Dannemora Skarn Iron Ore Deposit

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Franz Åberg; [2015]
    Keywords : Dannemora; ore; iron skarn; manganese; magnetite; skarn minerals; Dannemora; malm; järnskarn; mangan; magnetit; skarnmineral;

    Abstract : The Dannemora skarn iron ore deposit is located in the northeastern part of Bergslagen. The deposit has been mined from the 1400’s and stopped in 1992, the mine was reopen in 2012 and it will close in 2015. The Dannemora deposit is hosted by 1.9 Ga old sedimentary and volcanic rocks.
