秘鲁伊洛Morro1铜金矿地质特征及矿床成因

Morro1铜金矿位于秘鲁南部太平洋沿岸的早白垩世IOCG成矿带，是一个铜、铁矿异体共生的小型矿床，铜矿体伴生金矿化。基于普查工作成果，较系统地论述了矿床的地质特征，并与IOCG型矿床的典型特征进行对比分析，认为Morro1铜金矿在构造背景、矿化类型、矿石矿物组合、围岩蚀变等方面具有IOCG 型矿床的典型特征，可初步划分为IOCG型矿床；总结对比矿床地质特征，对矿床成因进行初步分析，将成矿作用过程划分为金属氧化物和金属硫化物2个阶段。

Geological characteristics and genesis of Morro1 copper-gold deposit in Ilo, Peru

The Morro1 copper-gold deposit is located in the early Cretaceous IOCG metallogenic belt along the Pacific Coast of southern Peru. It is a small deposit with allogenic symbiosis of copper and iron ore, and the copper body is associated with gold mineralization. Based on the results of the general survey, the geological characteristics of the deposit are systematically discussed and compared with the typical characteristics of IOCG deposit. It is considered that Morro1 copper-gold deposit has the typical characteristics of IOCG deposit in structural background, mineralization type, ore mineral association and wall rock alteration, etc., which can be preliminarily classified as IOCG deposit. On the basis of summarizing and comparing the geological characteristics of the deposit, the genesis of the deposit is preliminarily analyzed, and the mineralization process is divided into two stages: metal oxide and metal sulfide.
