Our upcoming speaker is one of our very own MGG professors: Peter Swart.
The title of his talk is "THE SCIENCE OF CLUMPED ISOTOPES".


ABSTRACT
Recent advances in stable isotope mass spectrometry have enabled the measurement of combinations of the rare isotopes of compounds.  For example carbon dioxide has a combination of 17O, 18O and 13C at mass 46, 47, 48, and 49.  These are known as clumped isotopes.  In the case of mass 47 it has been shown that deviations between the measured and the predicted distribution of mass 47 is rigorously dependent of temperature and not upon the isotopic composition of the fluid from which the mineral formed.  The recognition of this behavior and the scientific problems clumped isotopes can address has the potential open a Pandora's box of application in the geo and biogeosciences.

We hope to see you all there!

Your GEOTOPICS Coordinators,

Keri Vinas and Arash Sharifi
