隆兴铁矿赋存于太古宙夹皮沟岩群三道沟岩组和腰抢子片麻岩中。认为矿床成因类型是属于受变质（火山沉积）铁硅建造铁矿。富矿部分则是混合岩化热液作用，使铁发生迁移而富集的。确定三道沟组内的火山铁硅质沉积建造岩层是寻找此类型矿床的地层标志，而地球物理标志是地面磁异常强度在1000 nT以上的面积性异常即为矿致异常。

The Xinglong iron deposit occurrences in Archean ,Sandaogou Formation of Jiapigou rock group and Yaoqiangzi gneiss. It is considered that deposit genetic type belongs to metamorphic (volcanic sedimentary) iron deposit of iron silicon formation. Rich ore part is enriched by the migmatization hydrothermal process, and the migration. The identiifcation of Sandaogou volcanic iron siliceous sedimentary layer is a stratigraphic marker of this type ore deposit, and the geophysical marks are the ground magnetic anomalies in the area of the above 1 000 nT in intensity, that are anomalies related to mineralization.
