  1. 1. Magma Evolution of the Cerro Bayo Laccolith in the Chachahuén Volcanic Complex, Argentina

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Yang Sun; [2018]
    Nyckelord :Cerro Bayo laccolith; Chachahuén volcano; Thermobarometry; Plagioclase; Amphibole; Clinopyroxene; Cerro Bayo岩盖，Chachahuén火山，阿根廷，温压计，斜长石，角闪石，单斜辉石; Cerro Bayo lakkolit; Chachahuén vulkan; termobarometri; plagioklas; amfibol; klinopyroxen;

    Sammanfattning : The Chachahuén volcanic complex, with the Cerro Bayo laccolith as one of the largest intrusions, is part of back-arc Payenia volcanic province in western central Argentina. Laccoliths show potential for generating oil in sedimentary basins and producing ore deposits. LÄS MER

  3. 2. Magmatic Sources and Processes Recorded by the Volcanics from the Izu Bonin Rear Arc

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :John Owen Edgar; [2017]
    Nyckelord :Izu-Bonin; plagioclase; magma; strontium; thermobarometry; rear arc; Izu-Bonin; plagioklas; magma; strontium; termobarometri; bakbåge;

    Sammanfattning : The Izu rear-arc volcanism was investigated by IODP EXP350 in spring 2014. A total stratigraphy of1800 m was drilled, and contains volcaniclastic material within tuffaceous mudstone. LÄS MER

  4. 3. 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

  5. 4. 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

  7. 5. 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
