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

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Emelie Lagrosen; [2020]
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 2. Sulfide Mineralogy in the Ballachulish contact metamorphic Aureole

   Kandidat-uppsats, Institutionen för geologiska vetenskaper

   Författare :Ossian Åström; [2012]
   Nyckelord :Sulfide; mineralogy; Ballachulish; contact; metamorphic; aureole; pyrite; pyrrhotite; recrystallization; cordierite;

   Sammanfattning : 16 samples of increasing metamorphic grade from the Ballachulish Igneous Complex and Aureole, located in the west of Scotland, were studied in order to analyze the sulfide mineralogy and to what extent they were affected by contact metamorphism. The samples were collected from two lithologies, the Creran Succession and the Ballachulish Slate lithology, as well as from the igneous complex. LÄS MER
