  1. 1. 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

  3. 2. Norberg och Järnet : Bergsmännen och den medeltida industrialiseringen

    Författare :Ing-Marie Pettersson Jensen; Gert Magnusson; Anders Carlsson; Eva Svensson; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; iron production; mining; trade; landownership; social structure; Sweden; Dalarna; Västmanland; Viking Age; Middle Ages; arkeologi; Archaeology;

    Sammanfattning : This thesis is an archeological study of continuity and change in mining and settlement 1000 – 1500. At the time for the earliest possible introduction of mining, in the mid-10th century, the primary area for Norbergs’ mining district was sparsely settled, but in the late Viking Age and/or early Middle Ages, the analyses demonstrate a significant agricultural expansion.

  5. 4. Reflection seismic investigation in the Skellefte ore district : A basis for 3D/4D geological modeling

    Författare :Mahdieh Dehghannejad; Christopher Juhlin; Ari Tryggvason; Charles Hurich; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Skellefte district; reflection seismic; mineral exploration; 3D 4D modeling; mineralization; faults and shear zones; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : The Skellefte ore district in northern Sweden is a Palaeoproterozoic volcanic arc and one of the most important ones hosting volcanogenic massive sulfide (VMS) deposits, producing mainly base metals and orogenic gold deposits. Due to high metal prices and increased difficulties in finding shallow deposits, the exploration for and exploitation of mineral resources is quickly being moved to greater depths. LÄS MER

  7. 5. Data Mining Approaches for Outlier Detection Analysis

    Författare :Shahrooz Abghari; Niklas Lavesson; Håkan Grahn; Veselka Boeva; Olga Fink; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; outlier detection; data modelling; machine learning; clustering analysis; data stream mining; Computer Science; Datavetenskap;

    Sammanfattning : Outlier detection is studied and applied in many domains. Outliers arise due to different reasons such as fraudulent activities, structural defects, health problems, and mechanical issues. The detection of outliers is a challenging task that can reveal system faults, fraud, and save people's lives. LÄS MER
