Earth’s Volatiles from the Inside Out

Session ID#: 78919

Session Description:
Planetary differentiation and mantle dynamics left early Earth with a marble cake structure containing unmixed components. Volatiles distributed between these reservoirs record initial heterogeneity and mantle convection. Their degassing over different eras also affected early atmospheric evolution and ancient climate. In this session, we focus on how volatiles reflect heterogeneities during core formation, the giant impact/late heavy bombardment time, as well as degassing and cycling of volatiles from the interior to the atmosphere and their impact on ancient climate. We seek contributions from experimentalists, field geologists, geochemists, numerical modelers and seismologists with input on: (1) partitioning of volatiles between mantle and core during planetary differentiation; (2) volatiles in terrestrial and/or planetary samples/bodies that record mantle composition; (3) volatiles and mantle convection; (4) deep Earth volatile cycling and formation of diamonds; or (5) volatile outgassing mechanisms especially with implications for ancient climate. Contributions from early career scientists are especially welcome.
