  1. 1. Assessing a Modeling Standard in Volcanic-Geothermal Systems: the Effects of the Lower System Boundary

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Shelly Mardhia Faizy; [2021]
    Nyckelord :Geothermal; Numerical Modelling; Laccolith; Permeability; Topography;

    Sammanfattning : Geothermal energy consumption is projected to increase along with other renewable energy in the future. Therefore, it is important to have a better understanding on the evolution of geothermal systems to optimize the exploitation of such resources. Generally, numerical models are used as a fundamental tool to study a potential geothermal field. LÄS MER

  3. 2. Fracture characterization in magmatic rock, a case study of the Sosa-dyke (Neuquén Basin, Argentina)

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Nilsson Jim; [2020]
    Nyckelord :dyke; magmatic intrusion; fractures; Sosa dyke; permeability; intrusion; magmatisk intrusion; sprickor; Sosa intrusionen; permeabilitet;

    Sammanfattning : There are many examples worldwide were fossil magmatic intrusions influence the local water and energy supply. Due to that intrusions can act as a conductor and a reservoir, but also as a barrier for fluids and gases in the ground. The decisive feature between conductor or barrier in an intrusion is its fracture network. LÄS MER

  4. 3. The Crystal Size Distribution of Cerro Bayo

    Kandidat-uppsats, Uppsala universitet/Mineralogi, petrologi och tektonik

    Författare :Elin Kuylenstierna; [2018]
    Nyckelord :Crystal Size Distribution CSD ; magma chamber; igneous rock texture; Kristallstorleksfördelning CSD ; magmakammare; magmatisk bergartstruktur;

    Sammanfattning : To understand the complex structure of magmatic plumbing systems beneath volcanoes, one needs to study the different textures shown in the igneous rocks produced by the volcano in question. By doing this, one can get a clue of the processes that resulted in the final rock. LÄS MER

  5. 4. 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
