Dear colleagues,
We would like to draw your attention to our session, “Storage, cycling, and environmental consequences of magmatic volatile transfer from the mantle to the atmosphere” (V036) at this year’s AGU Fall Meeting in Washington, DC (Dec. 10-14, 2018). We invite you to consider submitting an abstract, and to join us at AGU.
V036. Storage, cycling, and environmental consequences of magmatic volatile transfer from the mantle to the atmosphere
Volatiles such as H2O, CO2, sulfur, and halogens influence melting, freezing, and redox in the solid Earth, while volatile exchange between the Earth’s interior and atmosphere plays a fundamental role in planetary and atmospheric evolution. Volatile cycling occurs through ingassing at subduction zones, storage and redistribution in mantle and crustal reservoirs, and outgassing via volcanoes, hydrothermal systems and diffuse degassing in tectonically active regions. The quantities, sources, variability, and mechanisms for each of these processes remain poorly constrained. This session highlights recent work on the storage, cycling and consequences of volatile transfer among Earth’s reservoirs throughout its history. This session welcomes contributions from geochemical, geophysical, climatic and modeling perspectives, including results from the Deep Carbon Observatory Deep Earth Carbon Degassing (DCO-DECADE) initiative, as well as contributions from the broader community interested in volatile exchange throughout Earth’s history.
Sincerely,
Tobias Fischer, James Muirhead, Taryn Lopez, Benjamin Black
