  1. 1. EBSD Investigation of High-Temperature Magnetite from Apatite-Iron-Oxide Deposits: Implications for the Formation of Giant Kiruna-Type Deposits

    University essay from Uppsala universitet/Mineralogi, petrologi och tektonik

    Author : Jens Henriksson; [2022]
    Keywords : Kiruna-type deposit; electron backscattered diffraction; crystal settling; Fe-O systematics; crystal alignment;

    Abstract : European iron production is to a large extent dependant on massive Kiruna type apatite-iron ore deposits. In this contribution, high-temperature magnetite samples from apatite-iron-oxide deposits are investigated by means of Electron Backscattered Diffraction. However, the origin of Kiruna-type deposits is still unresolved. READ MORE

  3. 2. Laser Ablation in Magnetites; Unravelling the Signatures of Trace Element Patterns for Ore Petrogenesis : Trace element signatures of magnetite linked to metallogenesis of iron mineralizations of the Kiruna type

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Siôn Kinson; [2020]
    Keywords : EPMA; LA-ICPMS; petrogenesis; magnetite; orthomagmatic; igneous; hydrothermal; alteration; EPMA; LA-ICPMS; petrogenes; magnetit; ortomagmatisk; stollande; hydrotermisk; förändring;

    Abstract : Trace element analyses of magnetite samples from multiple ore deposits worldwide have recently been conducted, using both EPMA and LA-ICPMS, in order to try and understand the petrogenesis of Kiruna-type ore deposits. Here I employ literature data and new data from Kiruna and Grängesberg (Sweden) to help constrain and visualise evolutionary trends recorded by our samples and derive an overall model for the evolutionary processes that lead to Kiruna-type deposits.

  4. 3. Oxygen and iron isotope systematics of the Grängesberg Mining District (GMD), Central Sweden

    University essay from Berggrundsgeologi

    Author : Franz Weis; [2013]
    Keywords : Grängesberg; Apatite-iron oxide ore; oxygen isotopes; iron isotopes; Kiruna-type; Eisenisotope; Sauerstoffisotope; Eisenerz; Grängesberg; Kiruna-Typ; Apatit-järnmalm; syreisotoper; järnisotoper; Grängesberg; Kiruna-typ;

    Abstract : Iron is the most important metal for modern industry and Sweden is the number one iron producer in Europe. The main sources for iron ore in Sweden are the apatite-iron oxide deposits of the "Kiruna-type", named after the iconic Kiruna ore deposit in Northern Sweden. READ MORE
