1. Petrophysical Properties of Rocks in Central Kiruna Mining District, Sweden
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : High economic and metallogenic significance of northern Norrbotten ore district in Sweden which hosts Kiruna mining district makes it a very important ore district in the world. Northern Norrbotten ore district contributes a combined 90 percent of iron production in Europe. LÄS MER
2. Geological characterization of rock samples by LIBS and ME-XRT analytical techniques
Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknikSammanfattning : 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
3. EBSD Investigation of High-Temperature Magnetite from Apatite-Iron-Oxide Deposits: Implications for the Formation of Giant Kiruna-Type Deposits
Master-uppsats, Uppsala universitet/Mineralogi, petrologi och tektonikSammanfattning : 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. LÄS MER
4. The Fe-oxides (mineralogical, chemical, and textural) variation in the Leveäniemi deposit using micro-analytical tools for unraveling of primary features and metamorphic recrystallisation
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : The Leveäniemi iron oxide apatite (IOA) deposit, mined by LKAB, is located in Norrbotten, northern Sweden. The deposit has a partially more complex mineralogy than the neighbouring and more famous IOA deposits of Kiirunavaara and Malmberget. LÄS MER
5. GEOCHEMICAL UNDERSTANDING OF VANADIUM IN MALMBERGET ORES (KIRUNA TYPE), NORTHERN SWEDEN
Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : The Norrbotten region is an important Swedish mining district with occurrence of several economic deposits and sub-economic deposits of apatite iron ores (Kiruna Type) and epigenetic Cu-Au ores. The apatite iron ores include the large Malmberget deposit mined by LKAB company as one of their world class underground mines. LÄS MER
