【 摘 要 】

The Akiri vein copper mineralization was investigated for its carbon and oxygenisotopic composition to determine the characteristics of the mineralizing fluid. Carbon andoxygen isotope analyses of Akiri siderite range between δ13C values (-1.05 to -1.71‰) and δ13Ovalues (-14.94 to -15.18) respectively. δ13C isotopic composition is comparable to valuesexpected for Cretaceous marine carbonates. The 18O depletion in the vein siderite indicatesdominant meteoric water sources involved for carbonates precipitation. This significant depletionbetween the δ18O compositions of Akiri siderite compared with carbonates from other parts of thebasin probably indicate differential formational temperature or fluid composition.
