  1. 11. The Significance of Giant Flank Collapses on Magma Ascent in the NE Rift Zone of Tenerife, Canary Islands: A Structural Modelling and Diffusion Approach

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Kristoffer Ånäs; [2021]
    Keywords : Tenerife; volcanic rift zones; analogue gelatine experiments; dykes; Fe-Mg diffusion; ankaramite; Teneriffa; vulkaniska sprickzoner; analoga gelatinexperiment; gångar; Fe-Mg diffusion; ankaramit;

    Abstract : On the volcanic ocean island Tenerife in the Canary archipelago, several giant flank collapses haveoccurred over the last one million years. The link between the lateral collapses and the resultingvolcanism in the rift zones is not fully understood and was investigated within the framework of thisproject. READ MORE

  3. 12. Origin of Silicic Magmatism at the Katla Volcano, South Iceland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Caroline Svanholm; [2021]
    Keywords : Katla volcano; Iceland; high-silica rocks; oxygen isotopes; AFC processes; Vulkanen Katla; Island; kiselrika bergarter; syreisotoper; AFC-processer;

    Abstract : 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

  4. 13. Methods for Studying Influence of Io Magma Ocean on Alfvén Wings

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Carl Lundquist; Fredrik Cumlin; [2020]
    Keywords : Io; magma ocean; Alfv ́en wings; plasma; mag-netic induction;

    Abstract : The most volcanically active body in the solar systemand the innermost Galilean moon of Jupiter, Io, is theorizedto have a global magma ocean beneath it’s surface. Io is alsoin a fast-moving flow of plasma where the moon acts as anobstacle in the flow which generates several complex interactions. READ MORE

  5. 14. Studying magmatic systems through chemical analyses on clinopyroxene - a look into the history of the Teno ankaramites, Tenerife

    University essay from Lunds universitet/Geologiska institutionen

    Author : Vendela Haag; [2020]
    Keywords : clinopyroxene; sector zoning; concentric zoning; mass wasting; magma recharge; Earth and Environmental Sciences;

    Abstract : Clinopyroxenes have the ability to crystallize over and respond to a large range of temperatures, pressures and chemical compositions, and thus, they are ideal for studies regarding the history of magmatic systems. In this thesis, the chemistry and zoning of four clinopyroxene crystals from an ankaramite sample from the Teno massif, Tenerife, were analysed. READ MORE

  6. 15. Magma-Carbonate Interaction and CO2 Release: A Case Study from Carlingford Igneous Centre, Ireland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Emelie Lagrosen; [2020]
    Keywords : Magma-carbonate interaction; CO2; calc-silicate; skarn; marble; Carlingford; SEM-EDX; XRF; LA-ICP-MS; Magma-karbonat-interaktion; CO2; kalk-silikat; skarn; marmor; Carlingford; SEM-EDX; XRF; LA-ICP-MS;

    Abstract : Magma which intrudes into carbonate rich crust, interacts with the carbonate in several ways, for example by contact metamorphism and formation of marble or by metasomatism resulting in calc-silicate skarn. These processes release volatiles, such as CO2, from the carbonate and might thus cause climate change. READ MORE
