| 中文摘要: |
| 邦沟矿床位于秘鲁利马南近550 km,是南美洲西岸一处大型的铁氧化物铜金(IOCG)矿床。磁铁矿资源量超过35亿t。文章通过对矿区地质特征、高磁异常、矿体特征、矿石矿物、矿化蚀变、构造演化等的综合研究,认为该矿床成因为夕卡岩型矿床,推测邦沟矿床形成过程中存在两期成矿事件。 |
| 英文摘要: |
| The Pampa de Pongo iron deposit, located approximately 550 km south of Lima of Peru, is the large-sized iron-oxide copper-gold deposit (IOGC)in the western coast of South America. The magnetite resource of the deposit reaches over 3500 Mt. Based on the comprehensive study on geological characteristics, high-precision magnetic anomaly, orebody characteristics, ore minerals, mineralization and tectonic evolution, it was concluded that the deposit belongs to skarn type deposit, and the deposit was formed in two mineralization events. |
