1. Paleontologiska egenskaper och syreisotopsutveckling i borrkärnan Limhamn-2018: Kopplingar till klimat- förändringar under yngre krita
Kandidat-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Krita är onekligen en av de mest omtalade tidsåldrarna inom paleontologin, inte minst på grund av massutdöendet som innebar slutet för alla icke-flygande dinosaurier. Nya studier visar att biodiversiteten hos storvuxna fågelhöftade dinosaurier började minska tiotals miljoner år innan utdöendet. LÄS MER
2. Origin of Silicic Magmatism at the Katla Volcano, South Iceland
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Katla volcano, South Iceland, is a bimodal volcanic system hosting an unusual high number of silicic rocks within a basaltic rift setting. The petrogenesis of silica-rich rocks at Katla is controversial and two end-member hypotheses have been suggested. LÄS MER
3. Implications of Magma and Bedrock Interaction, a Study of Xenopumice from La Palma, the Canary Islands
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : This thesis focuses on frothy, felsic xenoliths called ‘xenopumice’, that were retrieved from La Palma during a 10–day field campaign in December 2018. There are only few descriptions of these frothty xenoliths, and a consensus on their origin has not yet been achieved. LÄS MER
4. Grundvattenkarakterisering med syreisotoper : En fältstudie i Gäddviks vattentäkt i Luleå
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geovetenskap och miljöteknikSammanfattning : Groundwater and artificially recharged groundwater are important sources offreshwater in Sweden. In growing societies an ever larger demand is put onmunicipalities drinking water production facilities. LÄS MER
5. The population structure of Late Pliocene and Early Pleistocene Neptunea angulata, Gastropoda and an investigation into bias in the fossil record and museum collections.
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The fossil population structure of the gastropod Neptunea angulata from the late Pliocene and Early Pleistocene was investigated in this project in order to contribute to a wider study on the influence of predation on populations and the evolutionary history of organisms. Over time, predator-prey relationships can drive evolution in a way similar to the Red Queen Hypothesis. LÄS MER
