| 摘 要： | 鄂东铁矿地处长江中下游铁铜多金属成矿带西部,三叠系下统大冶群及中上统蒲圻群是鄂东铁铜矿主要成矿地层,岩浆夕卡岩型铁铜矿成矿与其关系密切.侵入接触带构造,捕虏体接触带构造,断裂叠加接触带构造,断裂构造是矿床的容矿构造.以中酸性岩为主的燕山期岩浆岩提供了主要的成矿物质来源.文章在系统研究以往地质物探资料的基础上,阐述了鄂东地区铁矿成矿地质特征,总结了该区铁矿的成矿规律,并进行了成矿预测,提出了下一步鄂东地区铁矿找矿方向.

| Abstract: | Iron deposits in the eastern Hubai are located in the west parts of lower - middle Yangtze Fe - Cu polymetallic metallogenic belt. Early Triassic Daye Group and Middle - late Triassic Puqi Group are host rocks of Fe - Cu deposits in the eastern Hubai. Magnmtic skarn Fe - Cu mineralization is main type. Contacting zones of intrusion, contacting zones of enclaves, contacting zones of overprinting by fractures, and faults are main ore - hosting structures. Yanshanian intermediate - acid rocks provide main metallogenetlc materials. Based on previous geological and geophysical data, geoiogicai features of Fe deposits in the eastern Hubai is elaborated, mineralization rules are summarized, mineralization forecast is proposed, and further ore - prospecting direction is suggested. |
