“…The main gangue minerals in deposits are quartz, barite, gypsum, and sulfosalt minerals (Pejatoviç, 1979;Çiftçi, 2000;Revan, 2010;Revan et al, 2014). Several rare minerals, such as kawazulite (Bi 2 Te 2 Se), hessite (Ag 2 Te), pyrrhotite (FeS), cervelleite (Ag 4 TeS), stützite (Ag 5-x Te 3 ), tellurobismuthite (Bi 2 Te 3 ), aikinite (CuPbBiS 3 ), emplectite (CuBiS 2 ), and wittichenite (Cu 3 BiS 3 ), have also been detected (Zaykov et al, 2006;Revan et al, 2014Revan et al, , 2019. Gold seems to be particularly common in these deposits.…”
