| 摘 要： | 铁氧化物-铜-金(IOCG)矿床与斑岩铜矿,因规模大、经济价值高而成为重要勘查目标.智利洋壳俯冲边缘汇聚了世界超大型斑岩铜矿和IOCG矿床,构造岩浆演化形成明显磁铁矿-磷灰石、IOCG、斑岩铜金、斑岩铜钼的成矿演化序列分带,大量钙碱性岩浆活动及同时代火成岩是重要成矿基础.岩浆侵位和流体演化是形成IOCG及斑岩型矿床的主要机制,IOCG矿床浅部角砾岩筒具有斑岩矿化蚀变特征,与富金斑岩型铜矿有更加相似的特征及过渡性,在勘查中要重视构造、岩相和蚀变研究.

| Abstract: | Iron oxide-copper-gold(IOCG) and porphyry copper deposits are all important exploration target due to their large-scale,high economic value.They are together generated in Chile subduction-related continental margin,including the world's large copper porphyry deposits,and have a sharp mineralization sequence in space-time from magnetite-apatite,IOCG,porphyry copper-gold to porphyry copper molybdenum deposits with tectonic-magmatic evolution.Large number of calc-alkaline magmatism and contemporary igneous roc... |
