  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

  2. 2. Magma Mixing and ReplenishmentBeneath Laurens Peninsula, Heard Island

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Ransom Telson; [2022]
    Nyckelord :Heard Island; Laurens Peninsula; crystal size distribution; magma replenishment; Heard Island; Laurens halvön; kristallstorleksfördelning; magmablandning; påfyllning;

    Sammanfattning : Heard Island is a remote Australian territory which lies in the South-middle sector of the Indian Ocean.The island lies in the central province of the Kerguelen Plateau. On the north-western face of the islandlies the Laurens Peninsula, where modern volcanism has been periodic since approximately 10 ka, butno eruption has been recorded. LÄS MER

  3. 3. The Significance of Giant Flank Collapses on Magma Ascent in the NE Rift Zone of Tenerife, Canary Islands: A Structural Modelling and Diffusion Approach

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Kristoffer Ånäs; [2021]
    Nyckelord :Tenerife; volcanic rift zones; analogue gelatine experiments; dykes; Fe-Mg diffusion; ankaramite; Teneriffa; vulkaniska sprickzoner; analoga gelatinexperiment; gångar; Fe-Mg diffusion; ankaramit;

    Sammanfattning : On the volcanic ocean island Tenerife in the Canary archipelago, several giant flank collapses haveoccurred over the last one million years. The link between the lateral collapses and the resultingvolcanism in the rift zones is not fully understood and was investigated within the framework of thisproject. LÄS MER

  4. 4. Methods for Studying Influence of Io Magma Ocean on Alfvén Wings

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Carl Lundquist; Fredrik Cumlin; [2020]
    Nyckelord :Io; magma ocean; Alfv ́en wings; plasma; mag-netic induction;

    Sammanfattning : The most volcanically active body in the solar systemand the innermost Galilean moon of Jupiter, Io, is theorizedto have a global magma ocean beneath it’s surface. Io is alsoin a fast-moving flow of plasma where the moon acts as anobstacle in the flow which generates several complex interactions. LÄS MER

  5. 5. Simulations of the lunar-forming impact using a new equation of state

    Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Robert Wissing; [2017]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : In this thesis we add a temperature dependence to the newly developed variable polytrope equation of state (Varpoly EOS) from Weppner et al. (2015), making it more universal and more applicable for planetary simulations. LÄS MER
