Origin and Transport of Volatiles in Planetary Interiors

Session ID#: 158305

Session Description:
The volatile elements exert strong controls on mantle melting and viscosity, planetary differentiation, plate tectonics and volcanism. Despite their importance in these processes, the origins, initial budgets, and internal distributions of the volatile elements on Earth and other planets is heavily debated. Global volatile cycling on Earth arguably provides and maintains our planet’s habitable status. The ingassing of volatiles via the subduction of volatile-rich lithosphere is countered by passive and volcanic outgassing at Earth’s surface. We seek contributions from geochemistry, experimental petrology, mineralogy, geodynamics, and seismology that speak to the origin and transport of the volatile elements (including highly and moderately volatile elements, and noble gases) on Earth and other planetary bodies.
