Current research interests

The investigation of a continent-derived alpine (U)HP nappe is crucial in order to reconstruct the evolution of the Alpine nappe through time until its present-time configuration. My research area is located in the Eastern Alps, in Austria and Slovenia, comprising the Koralpe-Saualpe-Pohorje Complex. In order to investigate the nappe structure, the following thermobarometric will be applied during my PhD (RSQI, Zr-in-rutile, and Zr-in-titanite thermometry and thermodynamic modelling). Different lithologies will be investigated comprising mainly eclogite which forms lenses within metasediments. During this study a profile along the Koralpe-Saualpe-Pohorje Complex will be sampled and investigated in detail, in order to test if tectonic overpressure occurred along the profile towards SE which reflects the direction of subduction of the nappe. Furthermore, it will be tested if there are structurally controlled variations in peak pressures and if there are systematic differences in peak pressures between different lithologies.


Current Grants

My project is funded by the DFG within the 4D Mountain Building Process (MB4D) SPP project.
