  1. 1. Metamorphic paragenesis and P-T conditions in garnet amphibolite from the Median Segment of the Idefjorden Terrane, Lilla Edet

    University essay from Lunds universitet/Geologiska institutionen

    Author : Anna Sartell; [2019]
    Keywords : P-T conditions; Sveconorwegian orogeny; Idefjorden Terrane; Median Segment; Göta Älv Shear Zone; garnet amphibolite; upper amphibolite facies; partial melting; Earth and Environmental Sciences;

    Abstract : The Sveconorwegian orogeny (c. 1 Ga) lead to the recrystallization of large parts of southwestern Sweden, with widespread metamorphism as well as local migmatization. READ MORE

  2. 2. Garnet amphibolite in the internal Eastern Segment, Sveconorwegian Province : monitors of metamorphic recrystallization at high temperature and pressure during Sveconorwegian orogeny

    University essay from Lunds universitet/Geologiska institutionen

    Author : Tove Hernnäs; [2018]
    Keywords : Sveconorwegian; metamorphic petrology; mapping; coronitic metagabbro; microtextures; Eastern Segment; Earth and Environmental Sciences;

    Abstract : The analyzed area exposes a deep underthrusting lower plate of the Sveconorwegian orogen and facilitates studying of an elsewhere hidden portion of the Earth. Petrographic and structural studies of different metamorphic rock types within the southern Eastern Segment, Sveconorwegian Province, Sweden, were carried out to better understand the regional metamorphism and deformation history.

  3. 3. Qualitative and quantitative petrography of meta-mafic rocks at Ölme, in the Eastern Segment of the Sveconorwegian orogen

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : Diana Carlsson; [2015]
    Keywords : metamorphism; high pressure; amphibolite; granulite; gabbro; metagabbro; garnet-amphibolite; complex coronitic textures; symplectite; Eastern Segment; Transitional section;

    Abstract : Meta-mafic intrusions with an intrusion age of 1.6-0.9 Ga are found along a north-south trend in theTransitional section of the Eastern Segment in Sweden. These intrusions are garnet-bearing and thus anexception to other meta-mafic intrusions found in Sweden. READ MORE

  4. 4. The Säm fold structure : characterization of folding and metamorphism in a part of the eclogite–granulite region, Sveconorwegian orogen

    University essay from Lunds universitet/Geologiska institutionen

    Author : Stephen Michalchuk; [2013]
    Keywords : anatexis; high-T granulite; interference folds; polydeformation; Sveconorwegian orogen; SW Sweden; Earth and Environmental Sciences;

    Abstract : Structural and petrological studies on complexly folded mafic and felsic layered sequences have been mapped in the parautochthonous basement of the Sveconorwegian Province, Sweden. Three deformation phases (D1, D2, D3)involving at least two fold phases (F2, F3) and two lineation phases (L2, L3) characterize a polyphase fold, which is primarily defined by a migmatized and highly competent garnet amphibolite.
