摘　　要：龙王庙铁矿位于清原县枸乃甸乡,毗邻二道沟铁矿。矿区内通过1∶10000高精度磁法测量,圈定了2处高磁异常区。矿体赋存于清原岩群红透山岩组,矿石以角闪磁铁石英岩为主,品位为15.15%~29.66%,平均mFe含量为22.90%。通过对龙王庙铁矿地质特征与磁异常特征研究,认为龙王庙铁矿为鞍山式沉积变质型铁矿,矿体分布受红透山岩组控制。该区内地表磁异常高值区及红透山岩组的叠合部位是成矿最有利地段,是寻找深部铁矿体的重要区域。Longwangmiao Iron Mine is located in Gounaidian Township,Qingyuan County,adjacent to Erdaogou Iron Mine.Through 1∶10000 high-precision magnetic measurement in the mining area,two high magnetic anomaly areas were delineated.The ore body occurs in the Hongtoushan rock group of Qingyuan rock group.The ore is mainly hornblende magnetite quartzite.The ore content is 15.15%-29.66%,and the average mFe content is 22.90%.Based on the study of geological characteristics and magnetic anomaly characteristics of Longwangmiao iron deposit,it is considered that Longwangmiao iron deposit is Anshan type sedimentary metamorphic iron deposit,and the distribution of ore bodies is controlled by Hongtoushan rock group.The high value area of surface magnetic anomaly and the superposition part of Hongtoushan rock group in this area are the most favorable areas for mineralization and are important areas for finding deep iron ore bodies.
