  1. 1. Magmatic processes and storage beneath Heard Island, southern Indian Ocean

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Liu Chun Wei; [2023]
    Nyckelord :Heard Island; Clinopyroxene; Thermobarometry; Magma storage depth;

    Sammanfattning : 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. LÄS MER

  3. 2. Relationship Between Hekla’s Magmatic System and Its Eruptive Behavior

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Eric Andin; [2017]
    Nyckelord :Hekla; crystal mush; thermobarometry; magma storage depth; Hekla; kristallansamling; termobarometri; magmalagringsdjup;

    Sammanfattning : The southern part of Iceland incorporates two parallel volcanic zones, the Eastern Volcanic Zone and the Western Volcanic Zone. These two branches are connected by an E-W transform. Hekla is located close to intersection between the two plate boundaries. Hekla is one of Iceland's most active and explosive volcanoes. LÄS MER

  4. 3. Crystallization and Emplacement of the Monte Amarelo Dikes: Magma Storage Assessment on Fogo, Cape Verde Islands

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Olle Risby; [2017]
    Nyckelord :Fogo; magma storage model; thermobarometry; clinopyroxene; intrusion landslide.; Fogo; magmalagringsdjup; termobarometri; klinopyroxen; intrusion; skred;

    Sammanfattning : The volcanic island of Fogo belongs to the Cape Verde archipelago, a two-tiered chain of islands situated 500 km west of the African coast. Fogo is regarded as one of the most active volcanoes in the world with 10 eruptions during the last 250 years. The former shield volcano Monte Amarelo reached 3500 m.a. LÄS MER

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

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

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

    Sammanfattning : 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. LÄS MER

  7. 5. Characterising the magma supply system of Agung and Batur volcanoes on Bali, Indonesia

    Master-uppsats, Uppsala universitet/Berggrundsgeologi

    Författare :Harri Geiger; [2014]
    Nyckelord :Bali; Batur; Agung; thermobarometry; clinopyroxene; plagioclase;

    Sammanfattning : Volcanic and magmatic processes are controlled by the composition of the magmas involved and the nature and structure of their underlying plumbing systems. To understand and predict volcanic behaviour, it is of critical importance to characterize the associated magmatic plumbing and supply system. LÄS MER
