PP31B:
New Insights on Geochemical Cycles toward Redox Proxy Development and Application to the Ancient Ocean and Atmosphere I Posters


Session ID#: 9011

Session Description:
We welcome submissions utilizing geochemical proxies, such as minor and trace elements (e.g., Mn, V, Cr, Mo, I, REEs) and/or isotopic techniques (e.g., C, O, S, Cr, Mo, U), as well as modeling approach to investigate atmospheric and seawater redox evolution as revealed by the sedimentary records over all geologic time scales. Contributions addressing issues related to proxy interpretation, such as the effects of diagenesis in modern and geological records, constraints on mass and isotopic composition of fluxes to and from the ocean, and isotopic or elemental fractionation during coevolution of the biosphere, are also invited.
