The Physics and Chemistry of Carbon in Planetary Interiors

Session ID#: 76039

Session Description:
The forms, transformations and movements of carbon in planetary interiors remain uncertain. This session highlights new results on carbon in minerals, melts, and fluids at extreme conditions. We invite contributions on carbon in all its oxidation states in carbon-bearing phases at pressures and temperatures of planetary interiors. Potential topics include, but are not limited to, the dynamics, structure, stability and reactivity of carbon-based natural materials, the properties of allied substances that carry carbon, the rates of chemical and physical transformations, and the complex interactions between moving fluids, magmas, and rocks. We welcome petrological, mineralogical, geochemical, experimental, and theoretical contributions which address our understanding of the physical and chemical behavior of carbon at extreme conditions.
