The PaleoGeochem group at the Department of Earth and Atmospheric Sciences uses various geological archives (e.g., speleothems and lake sediments) to help us better understand how our climate and our environment has changed and evolved through time.
We combine geochemistry, petrography, and mineralogy to answer some fundamental scientific questions about these past changes. The PaleoGeochem group combines a range of stable isotopes (d18O, d13C, d15N, dH, D47, and D17O) along with trace elements and other physical features of each geological archives to provide a comprehensive understanding of what has happened in the past. |
