The　Bor　metallogenic　belt　in　Serbia　is　a　promising　region　for　copper-gold　(Cu-Au)　resources,　hosting　numerous　porphyry　copper　deposits,　epithermal　gold　deposits　and　metallogenic　prospects,　such　as　the　South　Dulan　and　Vlaska　exploration　greenfield.　Epidote　alteration　is　integral　to　the　propylitic　and　sodic-calcic　alteration　assemblages　within　this　region.　It　is　distinguished　by　the　extensive　occurrence　of　two　primary　epidote　types:　disseminated　(Ep1)　and　veined　(Ep2)　epidote.　In　this　study,　comprehensive　petrographic　analysis　reveals　that　in　the　propylitic　zone,　epidote　mainly　replaced　hornblende　(Ep1a)　and　plagioclase　phenocrysts　(Ep1b),　coexisting　with　chlorite,　apatite　and　titanite.　In　proximity　to　the　potassic　zone,　epidote　(E1c)　coexists　with　biotite,　while　epidote　(Ep2),　chlorite,　pyrite　and　chalcopyrite　veinlets　are　observed　near　the　ore　body.　Notably,　Ep1　exhibits　lower　Fe　and　higher　Mn　contents　in　comparison　to　Ep2.　Additionally,　elements　such　as　Ca,　Al　and　Fe　in　Ep1a,　and　Ca,　Fe,　Mg,　Mn　and　Ti　in　Ep1b,　as　well　as　Ca,　Al,　Fe　and　Mn　in　Ep1c,　are　introduced　into　the　epidote　through　hydrothermal　fluid　interactions.　Variations　in　trace　element　characteristics　are　evident　among　different　epidotes.　Specifically,　Ep1a　exhibits　elevated　Mg　content　(324-6050　ppm),　Ep1b　is　notable　for　its　high　Na　(22-942　ppm)　and　Sr　(523-3075　ppm)　contents,　while　Ep1c　contains　elevated　K　(24-445　ppm)　and　Na　(41-103　ppm).　Which　suggest　that　disseminated　epidote　(Ep1)　inherits　the　geochemical　features　from　its　precursor　minerals.　In　comparison　to　disseminated　epidote,　epidote　in　veinlet　exhibits　higher　Fe3+,　Cu,　Sn　and　REEs,　along　with　lower　contents　of　Pb,　Sb　and　Sc,　suggesting　that　these　elements　have　been　integrated　into　epidote　through　isomorphism　substitution　and　influenced　by　fluids　compositions,　physical　factors　(temperature,　pressure,　etc.)　and　chemical　parameters　(speciation,　pH,　fO2,　etc.),　as　well　as　mineral　assemblages.　Therefore,　the　trace　element　contents　of　Pb,　Sb,　Sc,　Cu,　Sn　and　REEs　in　epidote　could　serve　as　more　appropriate　indicators　for　mineral　geochemistry　in　porphyry　deposit　hydrothermal　centers.
