| 摘 要： | 秘鲁首都利马至查拉400km沿海成矿带赋存多处铁、铜、金矿床,铜金矿床具有IOCG(铁氧化物)型,铁矿多为矽卡岩型。邦沟铁多金属矿规模巨大,矿床位于西科迪勒拉山西部边缘的伊卡-纳斯卡拗陷附近。矿床类型既有矽卡岩特征,也具有IOCG特点。总结矿床地质特征认为,邦沟铁和多金属矿矿化存在同期不同阶段的特点,铁矿化发生在第一期,铜金硫化物矿化发生在第二期;铜金硫化物在空间上与主铁矿体异位,铜金矿有较大找矿潜力。

| Abstract: | From Lima, the capital of Peru, to Chala City, there is a 400km long mineralization zone along the Pacific coast. In this zone, there are a number of iron, copper, gold deposits. The copper-gold deposits possess the special IOCG type characteristics, whereas the iron deposits are mainly of skarn type. Pongo is a huge iron deposit. The deposit is located in the Western Cordillera near the western edge of the depression of ICA to Nascar. The deposit is accompanied by copper-gold mineralization. This deposit not only has skarn specialty but also has IOCG features. The authors summarized the geological factors of the deposit and indicated an excellent copper-gold potential. It is also pointed out that the main iron mineralization and the gold-copper sulfides are different in stage and space. |
