A Perfect Match: Understanding Geochemical and Petrological Observations Through Combined Models of Geodynamics and Thermodynamics

Session ID#: 77646

Session Description:
Interpreting geochemical and petrological data in terms of physical processes in the subsurface remains a great challenge in Earth Sciences. One way towards a better understanding lies in combining physical models of geodynamics and reactive transports with thermodynamic models of petrology and geochemistry.


The goal of these models is to predict petrological and geochemical signatures to test against data, and to refine questions being asked of natural systems. However, building such models poses significant challenges. Apart from being formidable tasks in their own right, the geodynamic and thermodynamic model components are often developed by different communities and on different platforms.
This session aims to bring together investigators working on integrating models of geochemistry, petrology, geodynamics, and reactive transports. We encourage the submission of abstracts concerned both with methodology as well as application regarding how field and laboratory observations may point to physical processes in the subsurface.
