The petrological aspects concetrate on high grade rocks, especially in the formation of granulites. Granulite-facies metamorphism is widespread in crustal rocks formed in lower crustal domains at different times of ...

... the Earths history and thus forms an important part of the tectonic history of orogenic belts. Consequently, studies on metamorphic reactions and fluid/melt phases in such high-grade granulite facies rocks are important for the evaluation of processes in thickened continental crust. For a better understanding of the formation of these rocks, I am using classical methods such as macroscopic and microscopic observations as well as geothermobarometry, including modeling with PerPleX, thermocalc and TWQ software. Additionaly for better understanding of the fluid/melt bearing phases/processes, I am studying also fluid-inclusions to determine possible fluid phases according to the metamorphic history as well as to estimate possible XCO2 for phase petrological calculations of peak metamorphic conditions. The next aspect of the research of granulite facies rocks is Geochronology. Because lithologic and structural mapping of these multiple deformed and polycyclic high-grade terrains and the subsequent task of reconstructing its tectono-stratigraphy and overall geological history is an enormous challenge. Rocks in such terrains have their ancestry in the lower continental crust and are therefore pathways into the inaccessible lithosphere and are important for studies of geological processes related to the growth and stabilization of our continents.
