1. Lejarfjället Garnet(?) Peridotite – Origin and Petrological Characterization of Symplectitic Aggregates in Ultramafic Rocks
Kandidat-uppsats, Uppsala universitet/Mineralogi, petrologi och tektonikSammanfattning : Ultramafic rocks are abundant in the Earth’s mantle but rare on the surface. Since no in-situ samples from the mantle can be collected, mantle rocks provide knowledge of mechanisms operating in the mantle and large-scale processes that brought them up to the surface. LÄS MER
2. The Metamorphic History of the Helags Mountain Area, Scandinavian Caledonides
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The Scandinavian Caledonides formed as a result of collision between the continents Baltica and Laurentia, in Silurian and Early Devonian time. The evolution of the orogen has been a topic of research since before the turn of the last century. LÄS MER
3. Metamorphic Evolution of the Tjeliken Garnet-Phengite Gneiss, Northern Jämtland, Swedish Caledonides
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The Tjeliken Mountain in northern Jämtland, central Scandinavian Caledonides is by most authors considered to belong to the Lower Seve Nappe Complex (SNC). However, recently P-T conditions similar to the Middle Seve have been constrained for the eclogite at the top of the mountain, revitalizing the tectonic debate about Tjeliken. LÄS MER
4. Jämförande litologisk och geokemisk studie av Sevens amfibolitkomplex i Sylarna och Kebnekaise
Magister-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Sevekomplexet är ett 900 km långt och volymmässigt dominerande inslag i den övre skollberggrunden i de Skandinaviska Kaledoniderna. Komplexet representerar delar av Balticas passiva kontinentkant och havet strax utanför. Litologin domineras av metabasiter. Om dessa tillhör en och samma magmatiska händelse, representerar de en s.

5. Sierggavággeskollans strukturgeologiska utveckling : nyckeln till Sareks berggrundsgeologi
Magister-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : The Seve Nappe Complex (SNC) in the northern part of the Sarek Mountains, in NW Sweden, is characterized by large metamorphic contrasts between the individual thrust sheets. Eclogite facies and lower greenschist facies rocks are interleaved in a pattern that cannot be explained by normal in-sequence thrusting. LÄS MER
