Description/Abstract A model is presented which attempts to synthesize previous efforts to place the origin of planetary atmosphere and meteorite volatiles in a context more fully integrated with concepts concerning the early (and evolving) astrophysical environment of the solar system.^While the model combines familiar primordial components and theories, it differs from earlier approaches in that (1) the full ranges of observed isotopic variations are taken into account and attributed to a single fractionating process operating in nonnebular conditions, (2) the primordial volatiles are processed in defined astrophysical environments, and (3) the chronology for the various stages of planetary atmospheric evolution is directly connected with timescales for the evolution of surface activity on the early sun.^235 refs.
