Session No. 354: T40. What is old is new again: Using traditional and novel geochemical proxies to reconstruct past environments and their links to changes in the Phanerozoic biosphere (Part II)


Session Chairs:
Cole Tyler Edwards, Benjamin Charles Gill, Jeremy D. Owens, Theodore Roland Them, Seth Young

Description:

This session is focused on sharing recent advancements using new and traditional geochemical proxies to reconstruct paleoenvironmental conditions in order to better understand and constrain Earth–Life interactions throughout the Phanerozoic.
