Isotope Geochemistry, Geochronology and Thermochronology

About Us

  • Radiogenic and heavy stable isotope geochemistry
  • High-precision U-Pb geochronology
  • Low and high-temperature thermochronology

Congratulations to Philipp Widmann: His article "Calibrating chemical abrasion: Its effects on zircon crystal structure, chemical composition and U/Pb age" in Chemical Geology is online.

Fission Track Lab: Our fission track laboratory is back to routine operation. Congratulations to Diego Villagomez for this success!

Magmatism: Schaltegger et al. (2019) "Zircon petrochronology and 40Ar/39Ar thermochronology of the Adamello Intrusive Suite, N-Italy: Monitoring the growth and decay of an incrementally assembled magmatic system" is online;  doi:10.1093/petrology/egz010

Argon Laboratory: After many months of agony, our new Thermo Argus VI line has been measuring first UV-laser in situ Ar-Ar ages on K-feldspar megacrysts and  basalt groundmass IR-laser step heating ages! However, at 10 times higher blanks as we expected from the initial specifications, a problem still to be solved.
