The analysis of superthin parameters of interaction Mttssbauer spectra for Fe3+ and Fe2+ in basalt glasses in vicinity of the Bouvet triple junction is carried out. It is established, that Fe2+ ions in natural basalt glasses have effective coordination number about five, and Fe3+ ions are mainly in tetrahedral coordination. It is shown, that occurrence of crystal iron-bearing phases in glass is reflected in a change of the form of a function of distribution of quadrupole splittings. The method of restoration of functions of distribution of superthin parameters agrees with the description of Mossbauer spectra and structural features of natural glasses very well.
