Formation of volatile-rich lunar surface

Proceedings of the National Academy of Sciences

Using abundances and isotopic compositions of zinc, chlorine, and lead in a lunar rock known as the "Rusty Rock," researchers report that volatile elements and compounds found in lunar surface rocks formed through condensation of evaporated gases during cooling and crystallization of the early moon, suggesting that the lunar interior was correspondingly depleted of volatile elements and compounds, including water.
