A study on the determination of the complex structure of the electron-vibration spectra and the elucidation of their relation to crystallochemical factors in uranocircite is presented. The work was performed on samples from zones of a single crystal of the same natural meta-uranocircite, differing in color, and also on other specimens from various Soviet and foreign deposits. Of the 15 meta-uranocircite specimens investigated, in 14 cases the luminescence spectra were homoypic and were a series of equidistant groups of lines of the fine structure; the spectral position of which was practically constant for all the specimens. The degree of hydration was found to have practically no influence on the luminescence of the meta-uranocircite. The investigation supports the supposition that there are marked differences in the structures of minerals of the uran-mica group, although in the authors' opinion, the mechanism itself of multi-center radiation is universal and manifested for all secondary uranium minerals.
