  1. 6. 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

  3. 7. The Roots of a Magma Chamber, the Central Intrusion, Rum, NW-Scotland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Tobias Mattsson; [2014]
    Keywords : Rum; Layered Ultrabasic Intrusion; Long Loch Fault; 3D modelling; Rum; Minerallagrad magmakammare; Long Loch Förskastningen; 3D modellering;

    Abstract : The island of Rum in the Inner Hebrides, NW-Scotland, hosts a central volcanic complex that is part of the British-Irish Palaeogene Igneous Province situated in NE- Ireland and NW- Scotland. On Rum, rocks from several stages of Palaeogene magmatic activity have been exposed by millions of years of erosion. READ MORE

  4. 8. A geochemical characterization of the lower part of the Miocene shield-building lavas on Gran Canaria

    University essay from Lunds universitet/Geologiska institutionen

    Author : Romina Peetz; [2009]
    Keywords : Gran Canaria; shield-building lavas; Güigüi Formation; Earth and Environmental Sciences;

    Abstract : Ocean islands offer a great potential to provide information about mantle processes and the composition of the mantle. Gran Canaria is located in the centre of the Canary Island Archipelago and is well suited for such studies. A comprehensive study of the lower Miocene shield-building lavas is performed for this thesis. READ MORE

  5. 9. 1992-1998 seismicity and deformation at Mt. Eyjafjallajökull volcano

    University essay from Lunds universitet/Geologiska institutionen

    Author : Malou Blomstrand Stinessen; [1999]
    Keywords : Island; Mt. Eyjafjallajökull volcano; deformation; seismicity; geology; geography; Earth and Environmental Sciences;

    Abstract : Sammanfattning: Målet med detta examensarbete i tillämpad geofysik är att öka förståelsen för geologiska och geofysiska processer och deras samspel under vulkanen Eyjafjallajökull i södra Island. På Island har sedan ett tiotal år tillbaka använts geodetiska mätningar med Global Positioning System (GPS) instrument och geodetiska tiltmätare för att påvisa krustal deformation, som orsakas av vulkanisk, annan magmatisk eller seismisk aktivitet.
