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 “ultramafic” Intrusion’s within the peridotite from Härbergsdalen : Petrological characterization of infiltration record within the lithospheric mantle
Kandidat-uppsats, Uppsala universitet/Mineralogi, petrologi och tektonikSammanfattning : The mantle constitutes ~80% of Earths volume, however, due to its location deep beneath Earth’s surface the mantle is inaccessible to study in situ. Despite this, we still have information about its composition thanks to seismic studies which haven proven the mantle to be in generally homogenous and dominated by a rock called peridotite. LÄS MER
3. Unraveling the Tectonic History of the Aurek Metagabbro within the Seve Nappe Complex, Scandinavian Caledonides
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The Scandinavian Caledonides form a mountain range comprising nappe stacks of numerous far-travelled thrust sheets. The thrust sheets consist of diverse lithologies representing pre- and synorogenic sedimentary and igneous rocks subsequently metamorphosed to various degrees, from the Late Neoproterozoic to Middle Devonian.

4. Radiogenic Dating and Microstructure Analysis of Shear Zones Found Within the Seve Nappe Complex in the Åre Region, Jämtland, Scandinavian Caledonides
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The North Atlantic Caledonides are a continent-continent collision type orogeny found in WesternScandinavia, Svalbard, Greenland and the British Isles. They are thought to have formed as a result of a complex history consisting of repeated ocean opening and closure. LÄS MER
5. Pressure-Temperature-time Constraints on the Deep Subduction of the Seve Nappe Complex in Jämtland and southern Västerbotten, Scandinavian Caledonides
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The Scandinavian Caledonides are defined by long transported thrust sheets emplaced in a nappe stratigraphic succession onto the Paleozoic Baltica platform, as a result of the collision between the paleo-continents Baltica and Laurentia. This Palaeozoic collisional orogen is nowadays exposed at mid-crustal levels, thus provides an excellent ground for in situ studies of mountain building processes. LÄS MER
