Abstract of the proposed UNIPhD research project


The presently used model of the geological carbon cycle largely overlooks the contribution of crustally-generated magmas which inherit carbon from melting of carbon-bearing rocks. However, buried organic material which is transformed to graphite at depth likely represents another source of carbon in the deep crust. The aim of my research project is to understand and quantify the role of crustal anatexis in the deep geological cycle of carbon. The project utilizes a multidisciplinary approach which combines investigation of natural partially melted graphitic rocks, experimental work and thermodynamic modelling. It will lead to a better understanding of the carbon budget of the lower crust as well as help identify the origin and type of carbonic fluids at depth.



Short bio

Mikaela Krona is 26 years old and comes from Stockholm. She has always been curious about nature and wanting to understand the processes that govern it, which is what brought her to geology in the first place. Mikaela is in the last stage of completing her MSc degree in Geological Sciences and holds a BSc degree (2021) in Earth Sciences from Stockholm University. In her degree project, she used U-Pb geochronology combined with petrological data to refine the geometry of the nappe stack in the northern Dora-Maira Massif (Western Alps). Going forward, Mikaela is eager to start this PhD journey at the University of Padova.
