title: Moon: infrared studies of surface composition.
abstract: Infrared reflectance studies of small lunar regions reveal several absorption bands which match those of ferrous iron in laboratory spectra of olivines and orthopyroxenes. The craters Kepler and Aristarchus exhibit absorption bands suggestive of orthopyroxene, whereas the background mare material shows a band probably due to olivine.
