Mineralogical Magazine (2014) 78 (5): 1287–1299.
...S. Kharbish; P. Andráš Abstract Arsenopyrite (FeAsS), gudmundite (FeSbS) and the rarer Fe sulfosalts berthierite (FeSb 2 S 4 ) and garavellite (FeSbBiS 4 ), were investigated by Raman spectroscopy. Whereas (Sb,Bi)S 3 pyramids are responsible for the Raman spectra of berthierite and garavellite...
