Scientific paper

The effect is analyzed of variations in glass, end member abundance, and compositional variations on the reflectance spectra of glass and mafic silicate-bearing mineral mixtures chosen to reproduce spectral reflectance properties of lunar regoliths. The spectral properties of the glasses appear to be sensitive to parameters such as fusion techniques and initial composition. Variations in these parameters can yield classes which show spectral variations far in excess of those found for naturally occurring lunar impact-derived glasses and surface fines. The addition of glass to a mafic silicate-bearing assemblage results in a reduction in overall reflectance, band depths, and band area ratios, as well as a general decrease in band II minimum wavelength position and an increase in interband peak position.
