Reflectance spectra of manganese‐rich olivines were examined to determine which spectral features allow these minerals to be distinguished from forsteritic‐fayalitic olivines. The results indicate that manganese‐rich olivines can be distinguished on the following bases: Fe 2+ M2 absorption band depths are reduced relative to Fe 2+ M1 depths, the wavelength position of the Fe 2+ M2 absorption band is shifted to longer wavelengths (>1.08 μm) for olivines containing between ∼10 and 70 mol% Mn 2 SiO 4 , and the presence of an isolated Mn 2+ transition band near 0.4 μm. The absence of Fe 2+ spin forbidden features in the visible wavelength region is not a reliable method for identifying manganese‐rich olivines.
