We want to call your attention to a session at the GSA Annual Meeting on water-rock interactions.
On Earth reaction pathways of water-rock reactions can be observed directly, but elsewhere in the solar system we are often left with the mineralogical and geochemical products of these interactions to interpret the processes. On Mars, orbital and rover observations along with analyses of meteorites point to a rich history of water-rock interactions. Carbonaceous chondrites are typified by nearly complete alteration through the action of water. The Dawn
and Rosetta missions are exploring solar system bodies that have been modified by water. For planetary aqueous environments, big picture questions include:
(1) whether observed aqueous minerals formed at the surface or in the subsurface and under ambient or hydrothermal conditions and (2) the durations and volumes of liquid water involved.
The goal is to explore how exciting new results from mineralogic and geochemical studies based on orbital and landed measurements integrate with field, laboratory, meteoritical, and modeling investigations that address aqueous processes on planetary bodies.
Abstracts are due August 11:
