Abstract
High-sulphidation epithermal gold has been determined and studied in the Plavica deposit,
which is an integral part of the Kratovo-Zletovo volcanic area. Epithermal gold and associated mineral
phases have been determined in silicified tuff, secondary quartzite, quartz-pyrite-enargite veins and
mainly disseminated within an altered, but mostly silicified volcanic setting. Beside gold within this acidsulphate
volcanic environment was determined the presence of contaminated pyrite, zinc-tetrahedrite,
enargite, and certainly seligmanite regularly and commonly present copper association led by chalcopyrite,
followed by bornite, chalcocite, covellite, as well as slightly higher temperature associations of arsenopyrite
and molybdenite. Most of these accessory sulphide mineral phases within this study were observed
under state of the art polarized optical microscope, and the electron microprobe, which results are
presented in detail in this paper. For illustration we want to emphasize that in pyrite were found increased
concentrations of copper and zinc and less silver, then enargite with increased zinc concentrations (0.24–
7.56 Zn), antimony (0.46–1.33% Sb) and silver (0.09–0.54% Ag) , tennantite with increased iron (0.21–
1.55% Fe), zinc (6.24–9.06% Zn) and silver (0.08–0.87% Ag), while within the molybdenite elevated
concentrations were detected for sulfur and iron.
