河南许昌泉店-灵井铁矿床地质特征及找矿前景

Quandian-Lingjing iron ore deposit geological characteristics and prospecting prospects in Xuchang,Henan

泉店-灵井铁矿床位于河南省中部,是近年来河南省地质勘查基金在许昌铁矿成矿区发现的又一大型火山-沉积变质型铁矿床。矿体赋存于太古界登封岩群武庄岩组二段,呈层状、似层状多层产出,产状与围岩一致;由于受古断隆构造和含矿地层控制,矿体呈北西—南东向带状展布、且多呈断块产出。笔者在讨论矿床地质特征的同时,对区内磁异常特征、构造控矿因素、找矿标志进行了综合研究,认为该区深部沿矿体倾向方向和部分磁异常分布区尚有较大找矿空间。通过进一步勘查,矿床规模将会有很大的拓展空间。

Quandian-Lingjing iron ore deposit is located in central Henan Province,it is also another large volcanic-sedimentary-metamorphic iron ore deposits found in Xuchang iron ore metallogenic by Geological prospecting fund of Henan Province.The ore body whose occurrence in accordance with the surrounding rock suits in Segment 2 Wuzhuang group Dengfeng and outputs stratified and like stratified.Due to the ancient faulted uplift structure and ore-bearing strata control,the ore body distributes banded from North West to South East,and mostly block output.The author comprehensively studied characteristics of magnetic anomaly in the area,tectonic ore-controlling factors,prospecting marks while he discussed the geological characteristics of the deposit and included that there was large prospecting space along the direction of ore body tendency and part of the magnetic anomaly area in depth.Through further exploration,the ore deposit scale will have great development space.
