Welcome to the homepage of the Isotope Geology group at the University of Bern.
Our aim is to understand geological processes throughout Earth’s history. Therefore, we analyse a variety of radiogenic and non-traditional stable isotope compositions (e.g., Rb-Sr, Sm-Nd, U-Pb, Ca-Mo-Ti-Fe) in mantle samples (ophiolites, xenoliths, diamonds), meteorites, crustal rocks, sediments and fluids. We combine this isotope geochemical information with field observations, petrography, petrology, and various geochemical analyses to better understand cycling of elements and transfer of fluids/melts between Earth’s deep and surficial reservoirs through time, Earth’s differentiation processes and evolution of the mantle and crust. Isotope geochemical tools are also applied in collaborative projects in paleoclimatology, environmental science, and archeology.
Here we provide a short overview of ongoing research:
