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 (Pb3Sb4S11), jamesonite (FePb4Sb6S14), robinsonite (Pb4Sb6S13) 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. (C) 2016 Elsevier B.V. All rights reserved.
