  3. 2. Enhancing Mineral Carbonation of Olivine with CO2

    University essay from KTH/Kemiteknik

    Author : Ikaros Altantzis; [2023]
    Keywords : CO2 sequestration; Dissolution rate; Mineral carbonation; Olivine; Particle size; CO2-inlagring; Upplösningshastighet; Mineral kolsyrning; Olivin; Partikelstorlek;

    Abstract : Koldioxidutsläpp (CO2) från energiproduktionsindustrin och transportsektorn globalt påverkar miljön negativt. Länder har enats om att minska utsläppen för att nå målet om en genomsnittlig temperaturökning på 1,5 °C till 2030. READ MORE

  4. 3. Petrography and Mineral Chemistry of the Sälskär Breccia (Alnö Alkaline Complex, Central Sweden)

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Vincent Gustafsson; [2022]
    Keywords : Alnö alkaline complex; diatreme; melilitite; pelletal lapilli; volcanic breccia; Alnö alkalina område; diatrem; melilitit; pelletal lapilli; vulkanisk breccia;

    Abstract : Primitive magmas can provide important details about the mantle from which they are derived. In this thesis, petrographic observations and new mineral chemistry analyses of the Sälskär breccia from the Alnö alkaline complex, central Sweden, are reported. READ MORE

  5. 4. 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

  6. 5. Submarine Alteration of Seamount Rocks in the Canary Islands: Insights from Mineralogy, Trace Elements, and Stable Isotopes

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Aduragbemi Oluwatobi Sofade; [2018]
    Keywords : Canary Islands; seamounts; submarine alteration; trace elements; nannofossils; Kanarieöarna; djuphavsberg; undervattensomvandling; spårämnen; nanofossiler;

    Abstract : Seamounts play an important role in facilitating the exchange of elements between the oceanic lithosphere and the overlying seawater. This water-rock interaction is caused by circulating seawater and controls the chemical exchange in submarine and sub-seafloor rocks. READ MORE
