Photoelectric spectra of 10 luminous asteroids were obtained in the visible band with a spectral resolution of 2.5 nm. The existence of faint depressions in the asteroid spectra associated with absorption bands of the crystal field of iron-group elements was evaluated. Silicate minerals of some of the asteroids were found to contain iron-rich and calcium pyroxenes.
