Project: “Kinematic and thermobarometric evolution of subducting continental crust”

 

My research project is part of the joint DFG-funded project “Understanding subduction by linking surface exposures of subducted and exhumed crust to geophysical images of slabs” in the realm of the European AlpArray initiative.

 

I investigate a subducted and exhumed portion of the former European continental margin that is exposed in the central part of the Eastern Alps, in the so-called Tauern Window. The goal is to constrain the large-scale structure of this former continental margin, to decipher its subduction-exhumation history and to find out, how this structure developed into its current state. This will give insights into the mechanisms governing exhumation in subduction zones.

Additionally, we will use my reconstructions as input for synthetic seismic sections through subduction zones to find out if such structures can be imaged with seismological methods.

 

Methods I use:

- extensive field work for sampling, structural measurements and reconnaissance work

- thermobarometry and thermodynamic modelling

- structural analysis of the investigation area

- compilation of geological and tectonic maps

- geodynamic modelling

Fig. 6: Phase diagram of the sample depicted in Fig. 5, showing its inferred pressure-temperature evolution (white arrows). Dashed lines are measured minimum and maximum mineral compositions for Si p.f.u. in phengite (blue), XFe in Cld (green) and XFe in Grt (orange). Red line shows RSQI-Pressure as a function of temperature, with uncertainty interval (shaded pale red region).
