- W941520202 abstract "IOCG矿床是近些年来被认知的一种重要矿床类型，因其巨大的经济和理论研究价值受到国内外矿业界和学术界的重视。海南石碌铁钴铜（金）矿床在构造环境、与岩浆岩的关系、矿体特征、元素和矿物组合、围岩蚀变等方面与国外典型的IOCG矿床有相似之处。该矿床处于大陆边缘拉张的裂谷环境，早期火山沉积岩为成矿提供初始矿源，后期侵入岩对成矿具有重要的改造富集作用，矿体基本呈层状、似层状及少量脉状产于石碌群第六层中，一般铁矿体在上，钴铜矿体在下，具Fe—Cu—Co（-Au）多元素组合．铁氧化物主要为赤铁矿，蚀变以透辉石化、透闪石化为主；在成矿时代方面区别于多数产在元古宙的IOCG矿床，而是经历了新元古代海相火山喷流沉积阶段、加里东期区域变质阶段、海西一印支期热液改造阶段和燕山晚期热液改造阶段。文章认为石碌铁钴铜（金）矿床不仅与IOCG矿床有较多相似之处，与国内内蒙古白云鄂博铁稀土铌矿床、四川拉拉铜铁金钴钼稀土矿床、新疆乔夏哈拉铁铜金矿床、云南迤纳厂铁铜稀土矿床和东川稀矿山铁铜矿床等也有相似之处。因此，在中国开展寻找IOCG矿床尤其是大型矿床，是很有前景的。" @default.
