Trace elements in pyrite from the Čukaru Peki porphyry Cu–high-sulfidation deposit, Serbia: implications for ore evolution in a polyphase hydrothermal system

Čukaru Peki is a recently discovered porphyry- high-sulfidation Cu-Au deposit located 5km south of the mining town Bor in east Serbia. Three styles mineralization are distinguished system: type with massive sulfides (named Upper zone), porphyry Lower zone) and transition (between porphyries sulfides). This study investigates concentration distribution trace elements pyrite from these three zones Peki. The contains elevated concentrations V, Mn, Ni, Cu, As, Mo, Ag, Cd, In, Sn, Sb, Au, Hg, Tl, Pb Bi, compared to zone. zone Co Se. sample between two other zones, exception relative enrichment Ag. research also aims separate different stages ore deposition. stage several types veins: quartz A veins, B D magnetite purple anhydrite sulfide veins orange veins. high sulfidation formed stages: pyrite1, pyrite-enargite pyrite-covellite pyrite2 calcite-anhydrite There distinct differences various vein generations found within each zone, notable examples Se Cu (Cu, Bi) Py-cov comparison element data indicates change fluid compositions; earlier fluids responsible for showing slightly more magmatic signature (higher Co/Sb Se/As values) later bearing typical epithermal signature, which cooling diluting fluids.
