Since the long standing paradigm of a anhydrous Moon was challenged there has been a renewed focus on investigating volatiles in a variety of lunar samples. In particular, numerous studies have examined the abundances and isotopic compositions of volatiles in lunar apatites. In fact, apatite has been used as a tool for assessing the sources of water in the lunar interior. Furthermore, studies of lunar apatite may help in elucidating secondary processes, involving volatiles, which may have operated in the lunar crust. We report apatite data from two Apollo 17 samples which likely record post-crystallization metasomatic alteration that the host rocks experienced while residing in the lunar crust.
