1. Geologisk och geokemisk analys av 2 miljarder år gamla stromatoliter och kimberlit/lamprofyr från Kalix
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Den övergripande tanken med projektet är att ta reda på vad som hände på Västra Gräddmanhällan,utanför Kalix kust, för 2 miljarder år sedan. Det görs genom att ta reda på vad det är för bergarter ochstrukturer som hittats på området och hur de korrelerar till varandra. LÄS MER
2. Fracture characterization in magmatic rock, a case study of the Sosa-dyke (Neuquén Basin, Argentina)
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : There are many examples worldwide were fossil magmatic intrusions influence the local water and energy supply. Due to that intrusions can act as a conductor and a reservoir, but also as a barrier for fluids and gases in the ground. The decisive feature between conductor or barrier in an intrusion is its fracture network. LÄS MER
3. Temporal and genetical constraints of the Cu-Co Vena-Dampetorp deposit, Bergslagen, Sweden
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : The Bergslagen Province is known for containing major Zn-Pb-Ag and Zn-Pb-Cu-Ag sulphide mineralizations with associated iron-oxide skarns and a lot of research have focused on understanding them. However, Cu-Co deposits like the Vena-Dampetorp deposit have received less attention. LÄS MER
4. Magma Storage of the Alkaline Tejeda Cone Sheet Swarm, Gran Canaria, Spain
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Volcanoes with alkaline differentiated magma belong to the more explosive and destructive types, but knowledge about these systems is often limited. Unravelling the position and conditions in the source magma chamber systems that feed volcanism at the surface is vital to understand these systems better. LÄS MER
5. 3D Modelling of the Tejeda Cone-Sheet Swarm, Gran Canaria, Canary Islands, Spain
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Cone-sheet swarms are magmatic sheet intrusions and part of volcanic plumbing systems and are pathways for magma to the Earth’s surface, where they feed volcanic eruptions. The analysis of cone-sheets provides information on the geometry of the magmatic plumbing system of a volcano and allows to understand processes and dynamics of magma transport. LÄS MER
