Abstract

Mineralogical, chemical and spectroscopical investigations have been carried out on molybdenite from three southern Italy occurrences related to hercynian plutonites. Quartz veins in “granites”, worked some time ago, showed Mo-content ranging between 0.1 0.6 %. The observed paragenesis was quartz, molybdenite, molybdite, ferrimolybdite, chalcopyrite and chalcocite. Chemical analyses (microprobe), gave results very similar to stoichiometric values for $M_0S_2$, with minor Cu content. I.R. spectra, all identical, had significant peaks at 1088, 848, 723 and 469 cm-1. Diffuse reflectance U.V.-VIS spectra showed maximum absorbance values at 344.4, 588.4 and 648.2 nm. Furthermore, X-ray data confirmed all the molybdenite as the 2H polytypes; the investigated occurrences appear to belong to a “porphyry molybdenum” deposit.
