  1. 1. Magma-Carbonate Interaction and CO2 Release: A Case Study from Carlingford Igneous Centre, Ireland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Emelie Lagrosen; [2020]
    Keywords : Magma-carbonate interaction; CO2; calc-silicate; skarn; marble; Carlingford; SEM-EDX; XRF; LA-ICP-MS; Magma-karbonat-interaktion; CO2; kalk-silikat; skarn; marmor; Carlingford; SEM-EDX; XRF; LA-ICP-MS;

    Abstract : Magma which intrudes into carbonate rich crust, interacts with the carbonate in several ways, for example by contact metamorphism and formation of marble or by metasomatism resulting in calc-silicate skarn. These processes release volatiles, such as CO2, from the carbonate and might thus cause climate change. READ MORE

    Abstract : The cement and concrete industry stand for approximately 8% of the global CO2 emissions. The demand of concrete and cement is expected to increase rapidly with the growing world population and increased urbanization. This makes it of the utmost importance for the industry to try to mitigate its emissions. READ MORE

  4. 3. Exposure studies of refractory materials for biomass gasification

    University essay from Institutionen för tillämpad fysik och elektronik

    Author : Markus Carlborg; [2013]
    Keywords : Gasification; biomass; high alumina refractories; alkali; slag;

    Abstract : Gasification is a technology mostly used to convert fossil feedstock to syngas. Biomass could be used as a feedstock instead but that puts different demands on, among other things, the materials in these reactors. READ MORE

  5. 4. Investigation of a wollastonite occurence in central Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Anett Elg; [1987]
    Keywords : geography; geology; wollastonite; central Sweden; Earth and Environmental Sciences;

    Abstract : The wollastonite occurrence at Hulta is a skarn deposit associated with iron ore within the Leptite Formation of central Sweden. Wollastonite is found in carbonate layers within the leptite and the rocks have been subject to regional metamorphism. These layers are normally approximately 10 cm thick. READ MORE
