Description

The investigation of isomorphous substitutions in minerals of stannite group was carried out for two series Cu2FeSnS4 - Cu3SnS4 (stannite - kuramite) and Cu2FeSnS4 - Cu2ZnSnS4 (stannite - kesterite) by 57Fe and 119Sn Moessbauer spectroscopy. The calculation of the lattice contribution to the electric field gradient tensor at the 57Fe nuclei and an estimation of the quadrupole shift for the determination of Fe3+ atom positions in the structure were carried out. The charge and structural states of Fe and Sn atoms in compounds of the two systems were determined. The schemes of isomorphous substitutions were found for both series in all range of iron concentrations. The changes in the covalence degree of the bonds Fe2+ - S, Fe3+ - S and Sn4+ - S in the process of the substitution were found.
