  1. 1. 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

  3. 2. 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

  4. 3. Pit Craters of Arsia Mons Volcano, Mars, and Their Relation to Regional Volcano-tectonism

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jesper Perälä; [2015]
    Keywords : Structural geology; pit craters; crater chains; Arsia Mons; Mars; Strukturgeologi; kollapskratrar; kraterkedjor; Arsia Mons; Mars;

    Abstract : Pit crater and pit crater chains associated to the volcano Arsia Mons on Mars have been mapped to analyse their spatial pattern and to conclude about their formation. For the mapping, high resolution satellite data gathered during the Mars Express mission were used. READ MORE
