Luleå University of Technology is growing rapidly with world-leading expertise in several research areas. Our scientific and artistic research and education are conducted in close collaboration with international, national and regional companies, public actors and leading universities. Luleå University of Technology has an annual turnover of over SEK 2.3 billion. We have more than 1,800 employees and almost 21,600 students. Ore geology encompasses the use, behavior, occurrence and mode of formation of naturally occurring economic concentrations of metallic raw materials. The research aims to describe the geological conditions that lead to mineable concentrations of minerals, as well as how these minerals can be used for sustainable societal development. Project description Norrbotten hosts several occurrences of critical and strategic raw materials within Paleoproterozoic surface rocks overlying an Archean crystalline bedrock. Structural geologic models indicate that large-scale fault and shear zone systems extend into the Archean bedrock, and that the history of these structures has been important for deformation, fluid flow and development of the mineral systems in the surface rocks. However, the geometry, kinematics, temporal relationships and tectonic significance of these inferred bedrock structures remain poorly understood. The aim of the PhD project is to test and further develop existing structural geological models by integrating the Archean bedrock into a time-calibrated, multi-scale framework. Among others - Geological mapping and structural analysis of the Archean bedrock - 3D geological modeling of the bedrock architecture - Multi-scale deformation analysis and microstructural studies - Targeted petrochronological studies of magmatic and deformation-related events - Integration with regional geophysical models developed in parallel projects Duties and responsibilities A PhD position involves both theoretical and practical work. As a PhD student, you will be trained in scientific work through publication in international, peer-reviewed journals and through presentation of research results at national and international conferences. You will also take compulsory and elective doctoral courses and may participate in teaching or other departmental duties (maximum 20%). A central part of this project is independent, field-based geologic and structural mapping in northern Sweden, with considerable responsibility for planning and implementation. You will: - Plan, organize and implement field campaigns independently, including logistics and safety assessments. - Perform systematic structural measurements, kinematic analyses and representative sampling. - Integrate field observations into regional geological and structural framework models, carry out multi-scale interpretations and develop geological models consistent with regional tectonic frameworks. - Contribute to multidisciplinary data integration between geological, geochemical, geochronological and geophysical datasets. Fieldwork will be conducted in sparsely populated and topographically varied areas in northernmost Norrbotten, often under varying and sometimes demanding subarctic weather conditions. Ability and willingness to work outdoors for extended periods is a prerequisite. Qualifications We are looking for a highly motivated candidate with a strong background in structural geology and a clear interest in large-scale tectonics and mineral systems. Eligible for admission to the PhD program are those who have completed an advanced degree (Master's degree or equivalent) in Earth Sciences with a specialization in structural geology, tectonics, ore geology or related field. Particular emphasis will be placed on documented competence in: - Structural geology and kinematic analysis - Geological mapping and structural geological data collection in the field - 3D geological modeling - Multi-scale geological data analysis Experience of working in crystalline bedrock environments is highly advantageous. Experience in geochronology is an asset. Experience of geological fieldwork in northern Sweden or in similar subarctic environments is an advantage. The applicant should: - Have an interest in and enjoy extensive fieldwork in remote areas - Be able to work independently and take responsibility for the planning and implementation of field campaigns - Demonstrate analytical and problem-solving skills - Be able to communicate scientific results clearly in English, both orally and in writing - Possess a B driving license Written proof of good knowledge of English is required. Strong emphasis will be placed on personal suitability, autonomy and initiative.
