  2. 1. 3D Structure and Emplacement of the Alnö Alkaline and Carbonatite Complex, Sweden : Integrated Geophysical and Physical Property Investigations

    Author : Magnus Andersson; Alireza Malehmir; Valentin R. Troll; Bjarne Almqvist; Odleiv Olesen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alnö; carbonatite; caldera; reflection seismic; anisotropy of magnetic susceptibility; gravity; magnetic; Geophysics with specialization in Solid Earth Physics; Geofysik med inriktning mot fasta jordens fysik;

    Abstract : Carbonatites are carbonate-rich magmatic rocks that are rare and of great relevance for our understanding of crustal and mantle processes. Although found on all continents and in settings ranging from Archaean to present-day, their deeper plumbing system is still poorly understood. READ MORE

  4. 2. Magnetic anisotropy and paleomagnetism of precambrian rocks in the Fennoscandian shield

    Author : Håkan Johannes Mattsson; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics;

    Abstract : This thesis presents three applications of the anisotropy of magnetic susceptibility (AMS) technique, dealing with tectonic and magmatic flow fabrics of Proterozoic igneous rocks in the central and northern parts of the Fennoscandian Shield. Paleomagnetic measurements were performed in attempts to put the different rock units into a geological and plate tectonic context. READ MORE

  5. 3. Tectonic implications of ca. 1.45 Ga granitoid magmatism at the southwestern margin of the East European Craton

    Author : Audrius Cecys; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geologi; southern Sweden; fysisk geografi; physical geography; Mesoproterozoic; geochemistry; syntectonic; petrology; structural geology; anisotropy of magnetic susceptibility; Danopolonian orogeny; Geology; granite;

    Abstract : Between ca 1.53 and 1.40 Ga, the southwestern margin of the East European Craton was subjected to extensive magmatism and deformation. While various suites of anorthositic, mangeritic and charnockitic-granitic rocks were emplaced between ca. READ MORE

  6. 4. 3D-modeling of the Skellefte district using electrical, potential field and reflection-seismic data : A basis for 4D-modeling of mineral belts

    Author : Saman Tavakoli; Lena Persson; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics;

    Abstract : As a part of a 4D modeling project, two studies with different scopes were conducted in the central Skellefte district (CSD), northern Sweden. The aim of the studies is to create a basis for a better understanding of the spatial relationship between geological structures and mineralization and to construct a 3D and 4D geology model of the area.

  7. 5. Magnetic fabrics and paleomagnetism of the Storsjön-Edsbyn deformation zone, central Sweden

    Author : Håkan Mattsson; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics;

    Abstract : Anisotropy of magnetic susceptibility (AMS) and paleomagnetic data from the Storsjön-Edsbyn Deformation Zone (SEDZ) in central Sweden are presented. The SEDZ is a regional shear zone c. 200km in length that cuts through 1.7-1. READ MORE
