Geochronology

Determining the age and rates of geological processes involves the determination of precise and accurate ages for a particular event or for particular conditions, such as the pressure and temperature of metamorphic mineral reactions. Dating of a sequence of mineral reactions or of deformation increments provides key information for the quantification of orogenic processes and the understanding of their structural, rheological, and thermal development, as well as for the orogen-internal material redistribution via fluids and melts.

Fundamental and applied research on gas hydrates

Determination of thermodynamic, kinetic and physical properties of natural gas hydrates and synthesized mixed hydrates; application of basic knowledge on applied problems (e.g. gas production from hydrate bearing sediments).

Noble gas isotopes in geochemistry and geochronology

The chemically inert noble gases (or “rare gases”) helium, neon, argon, krypton and xenon are valuable tracers for various geochemical processes and can be used as dating tools in geochronology.

Geochemical technologies and methods

Geochemical technologies and analytical methods need to be continously further and new developed to solve urgent questions in geosciences.

Geochemistry of gases and fluids

Fluids (waters and gases) play an important role in almost all geological processes from the mantle to the surface of the Earth.

Magmatism and Earth Processes

We study magmatic rocks to learn about Earth processes that start deep and affect human habitat at the surface. Our research addresses the origin of magmas and what happens as they rise through the crust to form plutons, mineral deposits and volcanoes.

Material Cycles in Orogens

Radiogenic (Pb, Nd, Sr) and stable (Li, B) isotopes are used along with geochemical data to constrain material redistribution among various lithological units in orogens. Selective material redistribution is critical for the understanding of processes in orogens, but also for the formation of ore deposits.
