1. Enigmatic worm-like fossils from the Silurian Waukesha Lagerstätte, Wisconsin, USA
Kandidat-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : The lower Silurian Waukesha Lagerstätte of Wisconsin, USA, is a Konservat-Lagerstätte which has yielded a diverse assemblage of exceptionally well-preserved soft-bodied organisms. This study comprises first-hand descriptions and assessments of 23 enigmatic worm-like specimens from the Waukesha Lagerstätte, alongside a literature review. LÄS MER
2. Stratigraphy, sedimentology and geophysical assessment of the early Silurian Halla and Klinteberg formations, Altajme core, Gotland, Sweden
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : The Altajme drillcore was recovered from near Buttle in central Gotland in 2015. The core was drilled in outcrop belt of the late Wenlock (Silurian) Klinteberg Formation as a result from an international drilling campaign between the Department of Geology at Lund University and Iowa University, USA.

3. 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
4. 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
5. Stratigraphy, facies and depositional history of the Colonus Shale Trough, Skåne, southern Sweden
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Colonustråget är en viktig tektonisk enhet i den s.k. Sorgenfrei-Tornquistzonen i Skåne, södra Sverige. Den sedimentära sekvensen består av en kambrisk till silurisk succession dominerad av finkorniga klas-tiska sediment samt en mindre del kalksten. LÄS MER
