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

    Author : Lena Gunlög Albrecht; Berggrundsgeologi; []
    Keywords : 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;

    Abstract : 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°. READ MORE

    Abstract : This thesis consists of four subprojects: (A) ‘Clouding of plagioclase by Fe-Ti oxides’, (B) ‘Fe-Ti oxides during high-pressure metamorphism of mafic rocks’, (C) ‘Magnetic study of Fe-Ti oxides in mafic rocks and metabasites’, and (D) ‘Topotactic phase transitions in oxide minerals’. A) In southern Sweden dolerite dikes and gabbros with clouded plagioclase are common. READ MORE
