Raman spectroscopy of the Pb-Sb sulfosalts minerals: Boulangerite, jamesonite, robinsonite and zinkenite

Raman spectroscopy was used to investigate the lead–antimony sulfosalts minerals: boulangerite (Pb5Sb4S11), jamesonite (FePb4Sb6S14), robinsonite (Pb4Sb6Sl3) and zinkenite (Pb9Sb22S42). Raman bands of the investigated minerals that have interconnected SbS3 pyramids are found between 375 and 50 cm−1. The stretching and bending modes of SbS3 groups occur between 375 and 175 cm−1 in boulangerite, 350 and 180 cm−1 in jamesonite, 350 and 175 cm−1 in robinsonite and zinkenite. The investigated minerals show approximate similarities in their spectral features with those of minerals containing pyramidal SbS3 groups.
