| 摘 要： | 国际上对IOCG型矿床的研究如火如荼,中国则刚刚起步。文章全面评述了IOCG型矿床的研究现状,包括IOCG型矿床的定义、全球时空分布特点、成矿环境、与成矿有关的岩浆岩、矿体形态特征及围岩蚀变、矿床的形成过程、找矿评价标志等。最后,文章从IOCG型矿床的角度,对中国某些矿床进行了思考,认为长江中下游宁芜和庐枞盆地内的玢岩铁矿可能属IOCG型矿床,河北邯邢铁矿和湖北大冶铁矿也有IOCG型矿床的某些特点。

| Abstract: | The iron oxide copper-gold deposits (IOCG deposits) are being extensively and intensively studied abroad, but in China the study of such deposits is still in its beginning stage. In this paper, the authors present a review of the present research situation of the IOCG deposits, which includes definition of the iron oxide copper-gold deposits, temporal and spatial distribution, ore-forming environments, magmatic rocks associated with the deposits, shapes of the ore bodies and alteration of the country rocks, ore-forming processes and criteria for ore prospecting and evaluation. From the point of view of the iron oxide copper-gold deposits, the authors have pondered some IOCG deposits in China. The porphyrite iron deposits in the Ningwu and Luzong basins of the Lower Yangtze Valley probably belong to IOCG deposits, and the Daye iron deposit in Hubei Province and the Hanxing iron deposit in Hebei Province also have some IOCG features. |
