摘　　要：20世纪50至70年代和2011—2013年,在舞阳铁矿田内共提交铁矿石资源储量超过10亿吨,达到了超大型规模。舞阳铁矿田形成铁矿层的地层有赵案庄组、铁山庙组和杨树湾组,前两者能够形成大型或超大型矿床。赵案庄组所形成的矿层由原来的赵案庄矿层及其东部未进行资源储量估算的下曹余庄矿区和在2011—2013年普查中所控制的深部矿体组成,矿体自北西到南东基本相连。铁山庙组所形成的矿层由原来的经山寺矿矿区和铁山矿区及在2011—2013年普查中所控制的深部矿体组成,在经山寺矿区南侧铁山庙组矿层被赵案庄组所隔断,分为两个大区。通过总结最新整装勘查成果与科研成果,建立了舞阳铁矿田成矿-找矿模型,为国内外寻找该类型矿床及在该区进一步开展找矿工作提供参考。Wuyang Fe ore-field is a giant deposit with total proved resources and reserves of over 1 billion tons by decades of exploration from 1950-70 sand from 2011-2013.The deposits occur in Zhao＇anzhuang Formation,Tieshanmiao Formation and Yangshuwan Formation,and the former two groups can form large or super large deposits.The ore beds occurred in Zhao＇anzhuang Formation is composed of the ore beds of the former Zhao＇anzhuang,Xiacao-Yuzhuang and deep concealed ore beds proved by latest general exploration conducted from 2011 to 2013 with considerably continuous mineralization.The ore beds occurred in Tieshanmiao Formation consist of the ore beds of Jingshansi district,Tieshan district and the deep orebeds explored in 2011-2013.The ore beds in Tieshanmiao Formation to the south of Jingshansi district is separated into 2 segments by Zhao＇anzhuang Formation.In this contribution,combined with the previous achievements both in exploration and research,apattern for the exploration of Wuyang Fe ore-field is proposed and promotes further exploration of the same type of deposits.
