Our research interests reach from the formation of the Solar System to dating of geological processes and stuying the interaction between geo-, bio- and atmosphere.

Isotope analyses and mass spectrometry

  • Using TIMS, we date minerals and rocks on base of the abundances of radioactive isotopes and their daughter products (Prof. Bent Hansen, Dr. Klaus Wemmer).
  • Noble gas mass spectrometry allows dating of geological processes on base of the abundance of the 40-Ar isotope (Prof. Bent Hansen, Dr. Klaus Wemmer).
  • We use the ratios of stable oxygen, carbon and silicon isotopes to solve problems in the fields of geo- and cosmochemistry, but also atmospheric sciences. Notably that measurement of the abundance of the rare isotope 17-O opens a nev and innovative field in stable isotope research (Prof. Andreas Pack).

Experimental petrology and experimental cosmochemistry

  • Aerodynamic levitation in combination with laser heating allows melting of silicated and oxides without container. We study the formation of chondrules with this unique technique (Prof. Andreas Pack).
  • A gas mixing furnace allows to study the behavior of silicate melts in different gas atmospheres. We invstigate processes in the early stage of our solar nebular with this technique (Prof. Dr. Pack).

Geo- and cosmochemistry

  • We use aerodynamic levitation melting and LA-ICPMS for high-precision analyses of element ratios (e.g., Y/Ho, Zr/Hf, REE). Using elementa ratios, we want to study processes that have occurred during the formation of the fist solids in the Solar System by condensation from the gas phase (Prof. Andreas Pack).
