  1. 1. Magma Storage of the Alkaline Tejeda Cone Sheet Swarm, Gran Canaria, Spain

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Max Jensen; [2016]
    Keywords : Gran Canaria; Tejeda cone sheet swarm; syenite; magma storage; thermobarometry; clinopyoxene; Gran Canaria; Tejeda inverterade kon-intrusioner; syenit; magma förvar; termobarometri; klinopyroxen;

    Abstract : 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. READ MORE

  3. 2. 3D Modelling of the Tejeda Cone-Sheet Swarm, Gran Canaria, Canary Islands, Spain

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Lisa K. Samrock; [2015]
    Keywords : Cone-sheet swarm; 3D modelling; Tejeda caldera; Gran Canaria; magma chamber reconstruction; sheet intrusions; Inverterade koniska intrusionssvärmar; 3D-modellering; Tejeda kaldera; Gran Canaria; rekonstruktion av magmakammare; magmatiska intrusioner;

    Abstract : 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

  4. 3. Magmatic Sheet Intrusions as Seen in Surface Deformation - Developing a Tool for Interpreting Volcanic Unrest

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Frank Guldstrand; [2015]
    Keywords : Analogue modelling; surface deformation; cone sheets; dykes; moiré; photogrammetry; sheet intrusions; propagation; Analog modellering; ytdeformation; inverterade koner; vertikala plan; moiré; fotogrammetri; magmatiska intrusioner; propagering;

    Abstract : The end-member types of shallow magmatic intrusions comprise cone sheets and dykes. These propagate from their source magma chamber towards the Earth’s surface. The propagation of magma within the shallow part of the volcano plumbing system produces surface deformation and seismicity, signs of volcanic unrest. READ MORE
