Current research interests

My PhD project focusses on characterizing the principle mechanisms of eclogite-facies shear zone development in lower crustal rocks. On one of the best natural large-scale laboratories to work on such structures are the dry crustal rocks on the island of Holsnøy, Bergen Arcs in western Norway. Specifically, I combine detailed field mapping with microstructural observations and link them to mineral chemical data such as water content measurements of nominally anhydrous minerals (e.g. garnet, feldspar, pyroxene). This approach allows to evaluate the effect of fluid-rock-interaction processes on eclogite-facies shear zone widening within a thermodynamically metastable and continuously deforming environment. The main goal is to build up a numerical model that describes progressive fluid influx into crustal rocks, accompanied by shear zones widening using realistic structural geometries. The resulting simulations should deliver new insights into the transient weakening process of the mid to lower crust.

This project is imbedded in an interdisciplinary network including the UNIL – Université de Lausanne, Schweiz, the Ub – University of Bern, Schweiz and the JGU – Johannes-Gutenberg University in Mainz, Germany, aswell as the CRC 1114 Project – „Scaling Cascades in Complex Systems“.
