| Abstract | {The stable isotope composition of molybdenum (Mo) and zinc (Zn) in mine wastes al the Antamina Copper-Zn-Mo mine, Peru, was characterized to investigate whether isotopic variation of these elements indicated metal attenuation processes in mine drainage. Waste rock and ore minerals were analyzed W identify the isotopic composition of Mo and Zn sources, namely molybdeniles (MoS2) and sphaleriles (ZnS). Molybdenum and Zn slable isotope ratios are reported relative W the NIST-SRM-3134 and PCIGR-1 Zn standards, respectively. delta Mo-98 among molybdeniles ranged from -0.6 to +0.6 parts per thousand (n = 9) while sphaleriles showed no delta Zn-98 variations (0.11 +/- 0.01 parts per thousand, 2 SD |
