1. 6. Metadolerites as quantitative P-T markers for Sveconorwegian metamorphsim, SW Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Birgit Fredrich; [2014]
   Keywords : Earth and Environmental Sciences;

   Abstract : Strukturellt unga och N-S-ligt strykande högmetamorfa metadiabaser förekommer i Östra segmentet längs västkusten från Varberg till Kullaberg, och i inlandet mot öster till den Svekonorvegiska fronten. Dessa basiska gångar skär ställvis gnejsiga strukturer i värdbergarterna. READ MORE

3. 7. 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.

4. 8. Monazite in metasediments from Stensjöstrand : a pilot study

   University essay from Lunds universitet/Geologiska institutionen

   Author : Andreas Olsson; [2013]
   Keywords : pilot study monazit; Stensjöstrand; Sveconorwegian orogen; monazite; metasediments; metasediment; Sveconorvegiska orogenesen; pilotstudie; Earth and Environmental Sciences;

   Abstract : Monazit är ett Ree– och Th-bärande fosfatmineral som förekommer i vissa magmatiska och metamorfa bergarter. Mineralet är användbart för datering av den metamorfa utvecklingen och kan bidra till att yt-terligare karaktärisera metamorfosen i en bergart, detta genom att man undersöker zoneringar i kristallerna.

5. 9. Field relations, petrography and 40Ar/39Ar cooling ages of hornblende in a part of the eclogite-bearing domain, Sveconorwegian Orogen

   University essay from Lunds universitet/Geologiska institutionen

   Author : Nasim Mozafari Amiri; [2013]
   Keywords : Sveconorwegian; retrograde metamorphism; eclogite; Svarten Zone; ductile deformation; Ar-Ar dating.; Earth and Environmental Sciences;

   Abstract : High-pressure metamorphism and deformation of the Ullared Deformation Zone (UDZ) in the Eastern segment of the Sveconorwegian Orogen, southwest Sweden is evidenced by ~ 970 Ma retro-eclogite found in association with upper amphibolite and high-pressure granulite facies rocks. Petrographic, structural and geochronological studies of the UDZ were carried out to better understand the regional metamorphism and deformation history with focus on a ~N-S trending part of the zone influenced by a late stage of deformation during Sveconorwegian orogeny, namely the Svarten Zone.
