Abstract
The previously published data on S2•–-containing minerals of the sodalite, cancrinite and scapolite groups are summarized, and new data on the S2•– radical anion in haüyne with a commensurate modulated structure and in vesuvianite are presented. It is shown that the S2•– radical anion is quite widespread as an impurity in these minerals, affecting their colour as yellow chromophore, as well as such physical properties as luminescence, ESR, Raman and optical electronic spectra in the visible, near IR and UV regions. It is concluded that the S2•– radical anion plays an important role in the geochemistry of sulfur and can be considered as an informative geochemical marker.
