  1. 1. Lejarfjället Garnet(?) Peridotite – Origin and Petrological Characterization of Symplectitic Aggregates in Ultramafic Rocks

    University essay from Uppsala universitet/Mineralogi, petrologi och tektonik

    Author : Felicia Eriksson; [2022]
    Keywords : ultramafic; high-pressure metamorphism; peridotite; garnet breakdown; Scandinavian Caledonides; ultramafisk; högtrycks metamorfos; peridotit; granat; skandinaviska kaledoniderna;

    Abstract : Ultramafic rocks are abundant in the Earth’s mantle but rare on the surface. Since no in-situ samples from the mantle can be collected, mantle rocks provide knowledge of mechanisms operating in the mantle and large-scale processes that brought them up to the surface. 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. Magmatic water content and its effect on volcano explosivity; an FTIR investigation on the 2006 and 2010 eruption products of Merapi volcano, Indonesia

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Nadhirah Seraphine; [2018]
    Keywords : Merapi volcano; NAMs; clinopyroxene; magmatic water content; FTIR spectroscopy;

    Abstract : One of the most important volatiles in magma is water. In magma, water is incorporated in both the melt and in crystals, including hydrous and nominally anhydrous minerals (NAMs). READ MORE

  5. 4. A Petrological Investigation of the Host Rocks for the Kuj-Kiirunavaara Ore

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Holger Sandberg; [2018]
    Keywords : Kiirunavaara; optical mineralogy; hydrothermal alteration; electron microprobe; Kiirunavaara; optisk mineralogi; hydrotermal omvandling; elektron-mikrosond;

    Abstract : The Kiirunavaara mine hosts one of the world’s largest apatite-iron ore mineralisations. This ore body has been subject to large amounts of research as well as extensive mining. The ore body is situated between the syenitic foot wall and the rhyodacitic hanging wall, of which consists of differing mineralogy and characteristics. READ MORE

  6. 5. 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
