Volatile Acquisition During Terrestrial Accretion: Solar Wind (SW)-Implanted Neon in Cosmic Dust
Abstract
The "planetary" 20/22-Ne ratio of the atmosphereof (9.8) compares to the "solar" mantle value ( 12.5-12.7). Accretion of solar wind irradiated dust can supply sufficient Ne-B to Earth's interior while the late veneer generates the atmospheric ratio.
