1. Magmatic processes and storage beneath Heard Island, southern Indian Ocean
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : A young marine island called Heard Island is located in the southern Kerguelen Plateau in the Indian Ocean, a large igneous province created by the Kerguelen mantle plume. The two major geographic regions on Heard Island have two principal volcano-magmatic suites. READ MORE

2. Origin of Silicic Magmatism at the Katla Volcano, South Iceland
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : 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. READ MORE

3. The Crystal Size Distribution of Cerro Bayo
University essay from Uppsala universitet/Mineralogi, petrologi och tektonikAbstract : To understand the complex structure of magmatic plumbing systems beneath volcanoes, one needs to study the different textures shown in the igneous rocks produced by the volcano in question. By doing this, one can get a clue of the processes that resulted in the final rock. READ MORE

4. Geothermal Potential of Sub-Volcanic Intrusions in a Typical Caldera Setting
University essay from Uppsala universitet/Mineralogi, petrologi och tektonikAbstract : Sub-volcanic intrusions can form an extensive network of sills, dikes and other intrusion types that make up a plumbing system beneath volcanoes. Such intrusions are the heat source for high-temperature geothermal systems in volcanic areas and therefore, it is of great importance to study them in relation to geothermal exploration and production.

5. 3D Modelling of the Tejeda Cone-Sheet Swarm, Gran Canaria, Canary Islands, Spain
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : 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. READ MORE
