Lunar bulk sample 10084,85 (< 1 mm size dust), and samples from rocks 10017,17 (fine grained, vesicular), 10046,17 (breccia),
10057,59 (fine grained, vesicular, top surface), 10057,60 (fine grained, vesicular, interior), and 10058,24 (medium grained,
not vesicular) have been investigated by 57Fe Mössbauer spectroscopy. Iron metal and the Fe2+ minerals ilmenite, pyroxene, troilite, and iron
... [Show full abstract] containing glass have been identified. An iron line of sample 10084,85 (originally
sealed in nitrogen) showed no significant intensity change when the sample was exposed to air. The antiferromagnetic transition
in several lunar ilmenites at 570 ± 2°K corresponds to stoichiometric FeTiO,. Magneticallv separated 10057 showed troilite and somne metallic iron.
