As soon as lunar basalts became available for study, it was recognized from the absence of hydrated minerals from them, and the presence of metallic iron in them, that they were much drier and more reduced (oxygen-poor) than terrestrial basalts. Knowing just how reduced they are would improve our understanding of the composition of the
