Planetary volatiles

Initial and present volatile inventories and distributions in the Earth, other planets, meteorites, and comets; observational evidence on the time history of volatile transfer among reservoirs; and volatiles in planetary bodies, their mechanisms of transport, and their relation to thermal, chemical, geological and biological evolution were addressed.Sponsored by Lunar and Planetary Institute, National Aeronautics and Space Administration, National Science FoundationCompiled by the Lunar and Planetary Institute.PARTIAL CONTENTS: Accretion of volatiles / S.
