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

   Master-uppsats, Lunds universitet/Geologiska institutionen

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

   Sammanfattning : 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. 2. Determining host rock protolith in an altered VMS deposit in the Rävliden area, North Sweden

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Zana Mataruga; [2016]
   Nyckelord :Rävliden; lithogeochemistry; immobile elements; protolith; alteration; Rävliden; lithogeokemi; immobila element; protolit; omvandlingar;

   Sammanfattning : The Rävliden mine is located in the Skellefte district in northern Sweden. In close proximity lays the Kristineberg deposit containing zinc, copper and lead ore which has been mined since the 1940’s. The district is rich in massive sulphide deposits and the mining history can be dated back to the 1920’s. LÄS MER

4. 3. An investigation of the Felsic Ramiane Pluton in the Monapo Structure, northern Moçambique

   Magister-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Jonnina P. Karlsson; [2006]
   Nyckelord :Moçambique Orogenic Belt; Nampula Subprovince; Monapo Structure; Ramiane Pluton; Moçambique bältet; Nampula provinsen; Monapostrukturen; Ramianeplutonen; Earth and Environmental Sciences;

   Sammanfattning : Monapostrukturen ligger i Nampula provinsen i norra Moçambique, och utgör en del av Mocambique bältet. Strukturen är ca 35-40 km i diameter och har en mycket låg topografi. Trots detta syns den väl på satellitbilder och flygfotografier. LÄS MER

5. 4. Seveskollorna i nordöstra Kebnekaise, Kaledoniderna : metabasiter, graniter och ögongnejser

   Magister-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Anders Lundgren; [2002]
   Nyckelord :geografi; geologi; seveskollor; Kebnekaise; Kaledoniderna; metabasit; granit; ögongnejs; Earth and Environmental Sciences;

   Sammanfattning : The Seve Nappe Complex in the Kebnekaise Mts. is dominated by metabasites (Kebne Dyke Complex) and mylonitic gneisses. This study describes the tectonostratigraphy in two key areas (Nallo and Mårma) and investigates the origin of a granitic gneiss and two varieties of augen gneiss. LÄS MER
