Session 3n: Integrating geochemical proxies and geodynamics
Convenors: Christopher Spencer, Paul Tackley, Ross Mitchell
Keynote speaker: Jun Korenaga (Yale University)
Invited speakers: Elvira Mulyukova, Brenhin Keller
For decades, the fields of geochemistry and geodynamics have been viewed by many as only being loosely connected. “It’s only a model” has long been an excuse to explain the discrepancies between geodynamic modelling and empirical geologic evidence. However, recent advances not only in the accuracy of numerical modelling but also better understanding of the geochemical proxies used to constrain Earth processes has facilitated agreement between the geologic record and the numerical models used to describe them. The merging of geodynamics and geochemical proxies provides a clear avenue to constrain longstanding questions relating to the formation, evolution, and recycling of the lithosphere throughout geologic time. This session is aimed to highlight the advances in integrating geologic proxies and geodynamics. We welcome presentations spanning spatial and temporal scales from the planetary to mineral scale.
