V31B:
Triple Isotopes of Oxygen and Sulfur in Terrestrial Systems I


Submit an Abstract to this Session


Session ID#: 63635

Session Description:
Recent developments in high precision isotope analysis allow the resolution of systematic mass dependent variations in Δ17O, Δ33S and Δ36S of terrestrial materials. This caused a rapid growth of publications and emergence of labs with capabilities to produce high-quality triple isotope measurements providing novel insights into geological processes. We invite authors that work on theoretical and practical aspects of triple oxygen and multiple sulfur isotope geochemistry to contribute their abstracts to the session. The session is aimed to highlight research in the fields of atmospheric and surface geochemistry, early Earth processes, paleoclimate, mass spectrometry, water-rock interaction and other fields where triple and multiple isotope proxies proved to be a powerful tool.
