摘　　要：通过对软枣角沟铁矿的矿体特征及矿床成因分析，认为该铁矿严格受断裂构造和岩浆岩控制；岩浆岩主要为规模不等的变质斜长角闪岩体；矿区主要矿化带为M2、M6、M7、M9、M10，带内矿石类型主要为弱磁性块状、条带状赤铁矿；区内铁矿成因类型为热液交代型。Through analyzing the geological characteristics and deposit genesis of Ruanzaojiaogou iron mine, the paper states that the iron mine in this district is strictly controlled by the fault structure and granite. The granite mainly contains unequal size amphibolite of metamorphous and anorthosite. M2, M6, MT, M9 and M10 are the main mineralized belt. The weakly magnetic hematite in clump and band shape is the main ore type. The hydrothermal metasomatic is the main type of iron mine genesis.
