1. 1. Geophysical 3D models of Paleoproterozoic Iron Oxide Apatite mineralization’s and Related Mineral Systems in Norrbotten, Sweden

   Författare :Oskar Rydman; Maxim Smirnov; Thorkild Maack Rasmussen; Tobias Bauer; Niklas Juhojuntti; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Magnetotellurics; 3D Inversion modelling; Classification; Potential fields; Mineral system; Petrophysics; mineral exploration; common earth modeling; iron oxide-apatite; Northern Norrbotten ore province; Tillämpad geofysik; Applied Geophysics;

   Sammanfattning : The Northern Norrbotten ore district hosts a multitude of Sweden’s mineral deposits including world class deposits such as the Malmberget and Kirunavaara Iron oxide apatite deposits, the Aitik Iron oxide copper gold deposit, and a multitude of smaller deposits. Northern Norrbotten has been shaped by tectonothermal events related to the evolution of the Fennoscandian Shield and is a geologically complex environment. LÄS MER

3. 2. Paleoproterozoic deformation in the Kiruna‑Gällivare area in northern Norrbotten, Sweden : Setting, character, age, and control of iron oxide-apatite deposits

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kiruna; Gällivare; structural geology; Paleoproterozoic; deformation; Malmgeologi; Ore Geology;

   Sammanfattning : This thesis covers the structural evolution of the Kiruna‑Gällivare area in the northern Norrbotten ore province, Sweden. The study area hosts several economically significant iron oxide-apatite (IOA) deposits and includes the type locality for this ore type. LÄS MER

4. 3. Crustal architecture of the Kiruna mining district : Structural framework, geological modeling, and physical rock property distribution

   Författare :Ervin Csaba Veress; Tobias Bauer; Stefan Luth; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kiruna mining district; geological modeling; structural framework; common earth modeling; petrophysical characterization; mineral exploration; iron oxide-apatite; Ore Geology; Malmgeologi;

   Sammanfattning : Rapid technological advancements and growing environmental consciousness created a shifting dynamic of metal demand within the context of contemporary global challenges. The metals play a pivotal role in this transformation and remarkable surge in demand is expected. LÄS MER

5. 4. Structural evolution of two ore-bearing Palaeoproterozoic metasupracrustal belts in the Kiruna area, Northwestern Fennoscandian Shield

   Författare :Joel Andersson; Tobias Bauer; Olof Martinsson; Luth Stefan; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In this project, two key study areas in the northwestern Fennoscandian Shield are under investigation. The “Western supracrustal belt” and “Central Kiruna area” are both located along lithotectonically comparable Rhyacian-Orosirian metasupracrustal belts and both areas are characterized by iron oxide-apatite (IOA) and iron oxide-copper-gold (IOCG)-style mineralizations and related hydrothermal alterations.

7. 5. Utilizing a tectonic framework to constrain the mineral system and remobilization in the Kiruna mining district, Sweden

   Författare :Leslie Logan; Tobias E. Bauer; Fernando Tornos; Olof Martinsson; Paul Evins; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kiruna; tectonic framework; mineral system; IOCG; IOA; remobilization; sulfur isotopes; trace elements; geochronology; Pahtohavare; Viscaria; Rakkurijärvi; Malmgeologi; Ore Geology;

   Sammanfattning : The Kiruna mining district, located in the northern Norrbotten ore province, Sweden, is a geologically and economically important area, being the type-locality for Kiruna iron oxide-apatite (IOA) deposits and also host to a variety of other deposits including syngenetic stratiform exhalative Cu-(Fe-Zn) (Viscaria, Eastern Pahtohavare), epigenetic stratabound Cu ± Au (Pahtohavare), and iron oxide-copper-gold (IOCG, Rakkurijärvi) deposits. However, the timing of IOA versus IOCG within the tectonic evolution is in question based on structural investigations showing Cu- and Fe-sulfides occur in late-orogenic structures. LÄS MER
