Multiple-stage hydrothermal activities have resulted propylitic, phyllic, argillic alteration deposit. Five stages (I–V) activity are identified. Stage I represented a mineral assemblage epidote, chlorite, magnetite, some discontinuous barren veinlets quartz + K-feldspar ± fluorite magnetite epidote chlorite. II marked occurrence molybdenite pyrite sericite siderite veinlets/veins phyllic halos. III consists ankerite calcite chalcopyrite veins that commonly related dissemination altered rocks. IV has sphalerite galena coarse (10–20 mm wide). V narrow (≤5-mm wide) quartz. Molybdenite mainly occurs Stages III.Re-Os dating results samples from these two yielded isochron age 156.2 4.2 (2σ, MSWD = 0.96, n 10). Most high δ34S values (≥8.4‰) relative sulfide minerals (i.e., galena, sphalerite, pyrite, chalcopyrite) (δ34S 2.5–8.3‰, 22). also low 207Pb/204Pb 208Pb/204Pb ratios although there minor overlaps. In diagram 206Pb/204Pb versus 207Pb/204Pb, Pb isotope data display positive trend transecting growth curves crustal lead, which could be invoked mixing mantle sources distinct isotopes. combination S paragenesis, we magmas were main source molybdenum, whereas metals Pb, Zn, Cu) possibly sourced country You do not access content, please speak institutional administrator if you feel should access.
