Session ID#: 13166

Session Description:
Terrestrial worlds on which H2O-bearing fluids are stable tend to show a higher degree of chemical differentiation.  One important component in H2O-bearing fluids are the halogens; specifically F and Cl and, to a lesser degree, Br and I.  In such fluids, F and Cl are powerful reagents with respect to solution-enabled mass transport of cations.  This feature has many implications with respect to the reactivity of halogen-bearing fluids with most mineral species including the feldspars, Fe-Mg silicates, oxides, sulfides, and orthophosphates.

The goal of this session is to bring together a diverse group of geochemists with long-range interests, knowledge, and experience concerning the role of halogens during various geochemical processes in the crust and mantle of the Earth as well as other terrestrial worlds in the Solar System. Such a session should expand our current understanding regarding how halogens contribute to the geochemical/geophysical evolution and stability of terrestrial worlds overall.
