The volatile cycle within the Earth's interior
How volatile species are cycled within the deep Earth and whether they are fluxed back to the surface via volcanism.
Volatiles (H2O, CO2, Cl, S, F) are the major constituants of our planet. They mostly compose our atmosphere - hydrosphere and they shape the Earth as we know it today. Volatiles are efficently fluxed at subduction zones, where they are cycled into the deep mantle with the downgoing plate, and fluxed back to the surface via slab fluids. Recycling volatiles result in explosive volcanism and hazard, which in turn regulate climate and habitability of our planet.
My research seeks to further comprehend how much volatiles are fluxed back to the surface or lost into the deep mantle during subduction. Hence, identifying the nature, the composition and the spatio-temporal variations of the host reservoirs and the transfer agents (such as the slab fluids) of the volatiles is critical in better assessing the global volatile budget, which can provide, in return, insights into Earth's habitability and past climate changes.
