1. 1. Iron and Oxygen Isotope Signatures of Magnetite in Iron Ore of Kiruna Type

   Master-uppsats, Uppsala universitet/Mineralogi, petrologi och tektonik

   Författare :Malin Andersson; [2020]
   Nyckelord :IOA-deposits; magnetite; SIMS; EBSD; Fe- and O isotopes; laser fluorination;

   Sammanfattning : Stable isotope analysis of iron and oxygen isotopes in magnetite of Kiruna-type from Sweden and Chile have been conducted to further the understanding of the formation, and advance the analysis methods of these deposits. For this, data from SIMS (secondary ion mass spectroscopy), EBSD (electron backscatter diffraction) and triple oxygen analysis (by laser fluorination) are used. LÄS MER
