B.Sc. defence of Alaël Temmar

Our Bachelor student, Alaël Temmar from the University of Gothenburg did a great job in defending her B.Sc. thesis on June 1, 2023. Her thesis is called ‘Assessing the Carbon Sequestration Potential in Southwestern Sweden – A comparative study of igneous rocks from Greenland, Iceland, and Sweden to evaluate the carbonatization potential of the Billdal area, SW Sweden’. Supervisors were Erik Sturkell and Gabrielle Stockmann. Alaël has dedicated a lot of work and time on her B.Sc. work. She started as early as September 2022 and did daily measurements for several months in the fall. This was very much a pilot study inspired by the Carbfix sequestration method in Iceland, but applied to Swedish and Greenlandic rocks in addition to one fresh basalt from the Icelandic Holuhraun eruption 2014 – 2015. The Swedish igneous rocks were granite, gabbro, and dolerite from the Billdal area south of Gothenburg, whereas the Greenland rocks were nepheline syenite and carbonatite from the Grønnedal-Íka complex in SW Greenland. Luckily for the people of Billdal, there was absolutely no carbonate reactivity in the rocks from Billdal. This was expected for the granite, but that the mafic rocks should proof so inefficient came as a surprise. By further inspection, Alaël found out that all the pyroxenes, which could have provided the carbonatization potential had been altered into amphiboles. The Greenland rocks were semi-good, especially the carbonatite of course (consisting of calcite and siderite), but the most efficient was the young porous Icelandic basalt. Congrats to Alaël on a job well done, and for making a presentation that was extremely well presented and so professionally done that you almost forgot this was a B.Sc. defence. We wish Alaël all the best of luck on her future M.Sc. project and other endeavours!
