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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Liu Chun Wei; [2023]
    Keywords : Heard Island; Clinopyroxene; Thermobarometry; Magma storage depth;

    Abstract : 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. READ MORE

  3. 2. Studying magmatic systems through chemical analyses on clinopyroxene - a look into the history of the Teno ankaramites, Tenerife

    University essay from Lunds universitet/Geologiska institutionen

    Author : Vendela Haag; [2020]
    Keywords : clinopyroxene; sector zoning; concentric zoning; mass wasting; magma recharge; Earth and Environmental Sciences;

    Abstract : Clinopyroxenes have the ability to crystallize over and respond to a large range of temperatures, pressures and chemical compositions, and thus, they are ideal for studies regarding the history of magmatic systems. In this thesis, the chemistry and zoning of four clinopyroxene crystals from an ankaramite sample from the Teno massif, Tenerife, were analysed. READ MORE

  4. 3. Major and trace element geochemical analysis of norites in the Hakefjorden Complex to constrain magma source and magma plumbing systems

    University essay from Lunds universitet/Geologiska institutionen

    Author : Aodhan Barrett; [2020]
    Keywords : Anorthosite; norite; Plagioclase; Hakefjorden Complex; Sweden; Trace Elements; Geochemistry; Magma Origin; Earth and Environmental Sciences;

    Abstract : Major and trace element data taken from plagioclase crystals from anorthosites and related rock units in the Hakefjorden Complex located off the west coast of Sweden were investigated for the purposes of constraining magma chamber processes and the source of the magma. Although the anorthosite units were completely homogenous in regards to its chemistry, the plagioclase in the associated norite and ilmenite-leuconorite units showed substantial variation. READ MORE

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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Yang Sun; [2018]
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 5. Magmatic Sources and Processes Recorded by the Volcanics from the Izu Bonin Rear Arc

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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. READ MORE
