  1. 1. The Stollberg ore field - petrography, lithogeochemistry, mineral chemistry, and ore formation

    Författare :Magnus Ripa; [1996]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metamorphic; exhalative; hydrothermal; volcanogenic; skarn; magnetite; galena; sphalerite; Sweden; Bergslagen; Paleoproterozoic; deposit; mineralogy; geochemistry; Petrology; Petrologi; mineralogi; geokemi;

    Sammanfattning : The Paleoproterozoic Fe-Pb-Zn-Mn(-Ag) Stollberg deposit is situated in the Bergslagen region of south-central Sweden. 6.65 Mt of sphalerite, galena and manganiferous skarn magnetite ore occur as disseminations and semi-massive to massive ore bodies hosted by volcanogenic sediments and carbonate rocks.

  2. 2. Early structural and metamorphic evolution of the Scandinavian Caledonides: a study of the eclogite-bearing Seve Nappe Complex at the Arctic Circle, Sweden

    Författare :Lena Gunlög Albrecht; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; oblique compression.; C -type shear bands; anastomozing shear zones; tubular folds; lineation-parallel folds; northern Sweden; Grapesvare Nappe; Seve Nappe Complex; Finnmarkian; Eclogite; corona dolerite; Petrology; mineralogy; geochemistry; Petrologi; mineralogi; geokemi;

    Sammanfattning : In the Seve Nappe Complex of the Swedish Caledonides, coronitic diabases pass into eclogites; sometimes the transition occurs within one and the same boudin. Calculated pressure-temperature conditions for the eclogite facies stage are 20-27 kbar and 650-750°. LÄS MER

  3. 3. Sveconorwegian orogenesis in the southwestern Baltic Shield - Zircon geochronology and tectonothermal setting of orthogneisses in SW Sweden

    Detta är en avhandling från Department of Geology, Lund University

    Författare :Jenny Andersson; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Petrology; Geologi; fysisk geografi; physical geography; Geology; structural markers; augen gneiss; orthogneiss; migmatite; ion microprobe; Pb-Pb evaporation; U-Pb; geochronology; zircon; Sweden; Mylonite Zone; Western Segment; Sveconorwegian orogen; Eastern Segment; mineralogy; geochemistry; Petrologi; mineralogi; geokemi;

    Sammanfattning : The Mylonite zone (MZ) is a prominent late-Sveconorwegian lithological terrane boundary in the SW Baltic Shield along which large-scale crustal block movements took place during the Sveconorwegian orogeny. The southern section of the MZ also defines a conspicuous metamorphic break separating upper amphibolite and high-pressure granulite facies rocks in the parautochthonous Eastern Segment (ES), from middle amphibolite facies rocks in the overlying Western Segment (WS).
