This session addresses how volatile species affect dynamics of the
Earth and planets from natural observations, laboratory experiments, and
numerical modeling in the temperature, pressure, and oxygen activity
range from the early stage of the planet formation to the present. The
volatiles can be critical in zones of magma storage and ascent, mantle
upwelling and melting in the fluid-enriched subduction zones, in the
mantle transition zone, in the lower mantle, in the core-mantle boundary,
and in Earth and planetary cores. However, volatiles affect properties
and processes differently depending on their pressure, temperature, and
redox conditions, which vary in time and space.
This session aims to address how volatiles control the dynamic
processes of the Earth and planets, governed by their geophysical and
geochemical properties. We welcome papers dealing with geological and
laboratory observations coupled with numerical modeling on the role of
volatiles. The topics include (1) Stability relations, chemical and
physical properties of crystalline, molten and fluid phases,
partitioning of volatiles among these phases, (2) Rheological and other
physical properties of minerals, and the effects of intergranular fluid
on the properties, (3) Volatiles and dehydration induced seismicity and
volcanism in various tectonic regions including subduction zones, and (4)
Effects of volatiles in numerical simulation of geo-tectonics, and (5)
Magma outgassing and its control of volcanic eruption dynamics.
