title: Mossbauer spectrometry of lunar samples.
abstract: Nuclear gamma resonance measurements for the nuclide (57)Fe in lunar material were made in transmission on lunar fines and in scattering on intact lunar rock chips. No appreciable amnount of ferric iron was detected. Resonances were observed for ilmenite in all samples. Strong resonances attributed to ferrous iron in silicates, including pyroxenes and, in some samples, glasses and olivine, were also present. Metallic iron, alloyed with nickel, and troilite were also detected in the lunar fines. Differences in the spectra of various samples of lunar material and their significance are discussed.
