Abstract

Within this paper we are going to present results of our study of the Plavica deposit, Eastern Macedonia, epithermal gold and associated mineral phases that have been identified in silicified tuff, secondary quartzite, quartz-pyrite-enargite veins and mainly disseminated within an altered, but mostly silicified volcanic setting. Also, there we have 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 as slightly higher temperature associations of arsenopyrite and molybdenite. For illustration we want to emphasize that in pyrite we 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), as well as 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.
