| 摘 要： | 对湖北大冶铁矿的岩浆类型、矿体形态、矿石特征、围岩蚀变、成矿物质来源等进行分析,发现湖北大冶铁矿具备IOCG(铁氧化物-铜-金)型矿床的定义性特征,即铁氧化物含量高,伴生黄铜矿,贫硫化物、低钛,广泛受Na、K蚀变的热液矿床。另外,大冶铁矿与中酸性岩浆关系密切,且成矿物质来源于岩浆。作为IOCG型的大冶铁矿,其成矿环境为与非造山岩浆有关的大陆地块内部。 |

| Abstract: | Based on the analyses of magma type, ore body shape, ore features, wall-rock alteration and metallogenic material sources of Daye Iron Deposit, the authors found that the deposit was of characteristics of IOCG (iron oxide-copper-gold) deposits, with high content of iron oxide, accompanied by chalcopyrite, poor sulfide and titanium, widely affected by Na and K alteration. In addition, Daye Iron Deposit was closely related to the intermediate-acid rocks, and its metallogenic materials were derived from the magma. As IOCG type deposit, the metallogenic environment of Daye Iron Deposit belonged to the internal continental blocks related to nonorogenic magma. |
