  2. 1. Deformation zones in models and nature

    Author : Katarina Sofia Persson; Carl Ehlers; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; mineralogi; petrologi och tektonik; Mineral Chemistry; Petrology and Tectonics;

    Abstract : Field studies encounter several complicating factors not studied in the models. Examples are oblique convergence, heterogeneous materials and thermal softening by intruding magmas. READ MORE

  4. 2. 2D and 3D Reflection Seismic Studies over Scandinavian Deformation Zones

    Author : Emil Lundberg; Christopher Juhlin; Alireza Malehmir; Lars Nielsen; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Azimuthal binning; Crooked-line geometry; Cross-dip; Fault zone; Hard rock seismics; MTFC; Quick clay; Shear zone; UDZ; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : The study of deformation zones is of great geological interest since these zones can separate rocks with different characteristics. The geometry of these structures with depth is important for interpreting the geological history of an area. READ MORE

  5. 3. Integrated analyses and interpretations of regional scale magnetotelluric and potential field data from the Precambrian crust of northern Sweden

    Author : Roshanak Vadoodi; Thorkild Maack Rasmussen; Maxim Smirnov; Björn H. Heincke; Luleå tekniska universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Exploration Geophysics; Prospekteringsgeofysik;

    Abstract : The Norrbotten region in northern Sweden, as a part of the Fennoscandian (Baltic) Shield, is one of the most active mining areas in Europe. It is acknowledged that geological structures such as faults, shear zones, and associated fracture systems play a key role in providing a physical pathway connecting metal sources and the sites of mineral precipitation.

  6. 4. Tectonic Evolution of the Zagros Suture-and Imbricate Zones in Iraq

    Author : Maher T. Zainy; Maria Ask; Francisco Gomez; Luleå tekniska universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Tectonic evolution; Zagros Fold-and Thrust Belt; Remote sensing; Field feological work; 3D geological modelling; Natural resources exploration; Applied Geology; Tillämpad geologi;

    Abstract : Orogenic belts are expressions of tectonic activity, often host various natural resources (e.g. petroleum and minerals reserves), and influence the society and environment through hazards (e.g. READ MORE

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

    Author : Mahdieh Dehghannejad; Christopher Juhlin; Ari Tryggvason; Charles Hurich; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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;

    Abstract : 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. READ MORE
